UAC-0057 toolkit analysis and mitigation strategies from CERT-UA

Thu, 30 Jul 2026 06:09:53 +0300

Ukraine's cyberspace remains a constant battleground. Today, June 6th, CERT-UA issued a warning highlighting new tooling employed by the UAC-0057 group. This arsenal, comprising OYSTERFRESH, OYSTERSHUCK, and OYSTERBLUES, signifies an evolution in threats and necessitates enhanced cybersecurity measures for Ukrainian organizations. This is particularly crucial for those operating critical infrastructure or engaging with European partners, as it demands the implementation of comprehensive incident response and risk management processes aligned with NIS2 directive requirements.

Identifying cloaking techniques on compromised web platforms

Fri, 24 Jul 2026 09:21:34 +0300

For cybersecurity professionals, system administrators, and webmasters, a resource breach is a critical incident. However, the worst-case scenario is a compromise that remains unnoticed for months. Attackers have learned to monetize the reputation of legitimate corporate websites to promote spam and phishing in such a way that business owners see no signs of a problem during normal browsing.

This concealment technique is called cloaking. It allows displaying a perfectly clean, functional site to administrators and auditors, while malicious content is served to search bots (e.g., Googlebot). In this article, we will analyze the mechanics of cloaking, the logic of its implementation at the web server level, and the detection methodology via Google Search Console (GSC) with subsequent analysis of HTTP headers.

AI security: preventing data leaks and prompt injection in services

Thu, 23 Jul 2026 23:44:35 +0300

By 2026, artificial intelligence (AI) has transitioned from an experimental technology to an integral part of business processes, particularly in the banking sector. From chatbots for support to fraud detection and risk analysis systems, AI services process vast amounts of confidential data and participate in decision-making. Consequently, their security has become a paramount concern. The rapid integration of AI into critical infrastructure and the rise of associated cyber threats make strengthening defenses an urgent task for 2026-2027.

Rapid offboarding: securing SaaS, IAM, VPN, and service account access within 24 hours

Wed, 22 Jul 2026 10:14:39 +0300

As phishing remains the leading vector for initial access, according to the ENISA Threat Landscape 2025, a terminated employee's account cannot be treated as a mere technical formality. It is a potential channel for unauthorized entry, especially when access is distributed across IAM, VPN, SaaS applications, repositories, cloud resources, and service accounts.

Therefore, offboarding must be more than just an HR procedure; it should be a managed 24-hour security transaction with a clear trigger, designated owners, forced termination of active sessions, network access closure, auditing of local SaaS accounts, and the transfer of rights to critical resources before user deletion.

Applying Zero Trust to legacy ERP via PAM, IAP, and microsegmentation

Mon, 20 Jul 2026 17:33:44 +0300

Legacy ERP often remains the "heart" of an enterprise: it handles finances, procurement, production, logistics, and management reporting. At the same time, such systems often lack support for modern multi-factor authentication, SAML/OIDC, contextual access policies, or sufficiently granular privilege control. Completely rewriting the code or replacing the ERP can be too risky for business continuity, so a CISO needs an intermediate, yet manageable, path to risk reduction.

The threat landscape makes this task practical rather than theoretical. The ENISA Threat Landscape 2025 identifies phishing as the leading initial access vector. In the same reporting period, 53.7% of organizations affected by cyberattacks belonged to essential entities within the scope of NIS2. For industry, critical infrastructure, and large enterprise organizations, this means that if a user account is compromised, the ERP must not remain an open target for direct access and lateral movement.

Managing AI risks in critical infrastructure using the NIST AI RMF 1.0 framework

Fri, 17 Jul 2026 09:00:24 +0200

The rapid adoption of artificial intelligence in critical infrastructure management systems requires organizations to look beyond simple model accuracy assessments. The focus is shifting toward implementing comprehensive risk management frameworks that ensure safety, reliability, and accountability. Critical infrastructure operators face unique challenges: managing specific security risks of AI systems cannot be limited to performance metrics alone but requires integration into a broader operational security architecture.

The accuracy trap: why high performance does not guarantee AI security

For artificial intelligence systems in critical infrastructure, the U.S. National Institute of Standards and Technology (NIST) emphasizes the need to evaluate context, potential harm, reliability, and safety rather than focusing exclusively on model accuracy. The non-deterministic nature of machine learning models creates a specific threat landscape where even a high-precision algorithm can become a source of critical failure or an attack vector.

Addressing mass URL injection and related SEO vulnerabilities

Thu, 16 Jul 2026 10:21:21 +0300

Imagine a scenario where a CISO or platform owner receives an alert from Google Search Console. The number of indexed pages for a corporate resource has suddenly jumped from a few hundred to tens of thousands. The list of addresses now includes paths containing pharmaceutical names, gambling terms, or nonsensical parameters. The instinctive reaction is often to set up a mass 301 redirect of all unknown URLs to the homepage to quickly hide the issue and supposedly save SEO metrics.

Investigating unknown sitemaps in GSC: legacy CMS or security breach

Tue, 14 Jul 2026 13:39:44 +0300

The appearance of an unknown sitemap in Google Search Console (GSC) is an alarming signal that corporate web resource administrators and IT department heads often underestimate. Instead of recognizing it as a marker of site compromise, the incident is frequently dismissed as a technical glitch or the result of legacy plugins.

As cybersecurity experts note, such an artifact is most often the result of content injection and page injection. In this situation, chaotic deletion of the suspicious file does not solve the problem but merely destroys the digital evidence needed for forensic analysis, leaving backdoors for persistence.

DLP methodologies for protecting corporate content in remote work

Mon, 13 Jul 2026 06:12:08 +0300

Distributed work and challenges for DLP

Projections indicate that by 2026, over 70% of global companies will adopt hybrid work models, posing substantial challenges to traditional data protection strategies. Distributed infrastructure, the use of personal devices (BYOD), and the proliferation of cloud services increase the risks of confidential information leakage. Classic perimeter security measures are becoming insufficient, necessitating a shift towards more flexible and intelligent DLP solutions based on context and behavioral analysis.

Preventing privilege creep and ensuring secure off-boarding with IAM and PAM

Mon, 13 Jul 2026 02:35:06 +0200

In the modern era of hybrid work and distributed cloud infrastructures, the concept of a traditional network perimeter has finally lost its effectiveness. User identity has become the only real line of defense. In the Zero Trust paradigm, every access request must be authenticated, authorized, and verified. It is important to understand that implementing Identity and Access Management (IAM) and Privileged Access Management (PAM) tools does not eliminate cyberattack risks by one hundred percent. However, it is a critical architectural layer of protection that limits the blast radius and complicates lateral movement for attackers in the event of a compromise.

Post-hack SEO recovery: clearing spam URLs from search indexes

Mon, 06 Jul 2026 17:08:26 +0300

After a site hack, the technical team often focuses on the obvious: removing malicious code, closing vulnerabilities, changing access credentials, and restoring the site to operational status. However, this is not enough for SEO. If attackers managed to create spam pages, add hidden links, or configure malicious redirects, some of this content may remain in search results even after the server has been cleaned.

Google classifies content added to a site without permission via a vulnerability as hacked content. For a business, the problem is not just a technical incident: users may see pages with irrelevant or compromising queries in search results, and search engines may continue to crawl URLs that should no longer exist. Therefore, SEO recovery after a hack is a separate post-incident process: inventorying infected URLs, setting correct HTTP responses, temporarily hiding critical content in Search Console, updating the sitemap, and submitting a final review request in the Security Issues report.

Zero Trust implementation for hybrid environments where traditional perimeters fail

Mon, 06 Jul 2026 00:23:52 +0200

The shift to hybrid infrastructures, combining on-premises resources with cloud services, has blurred the traditional boundaries of corporate networks. Oleh Kravchenko, a cybersecurity engineer, notes that under these conditions, the network perimeter—which has been the foundation of security for decades—is no longer a sufficient line of defense. The rise of remote work, the adoption of SaaS solutions, and BYOD policies demand a fundamentally new approach to security, where trust in any user or device is absent by default. This concept, known as Zero Trust, is becoming not just a recommendation but a mandatory requirement for protecting corporate data and systems.

Detecting Casibom-related corporate website compromises via Search Console

Fri, 03 Jul 2026 13:03:30 +0300

Imagine opening your morning Google Search Console report for your corporate portal and seeing a surge in impressions for queries like "Casibom güncel giriş," "Slot oyna," or similar Turkish gambling terms. Since your organization has nothing to do with online casinos, your first reaction might be to dismiss it as an analytics error. However, the reality is much harsher: your web resource has been compromised.

According to the ENISA Threat Landscape 2025 report, approximately 27.7% of analyzed data breaches and security incidents involve digital infrastructure and services. Attackers increasingly exploit corporate website vulnerabilities not for direct database theft, but for SEO spam, leveraging the trust associated with your domain. The appearance of such queries is a critical marker of an incident that requires immediate technological response, rather than simply deleting pages.

Transitioning the public sector from baseline compliance to active cybersecurity

Wed, 01 Jul 2026 06:08:12 +0300

The Ukrainian government's Computer Emergency Response Team, CERT-UA, issued a warning on May 21st of this year regarding an updated toolkit used by the cyber group UAC-0057. This group is actively employing new malware, OYSTERFRESH, OYSTERSHUCK, and OYSTERBLUES, in phishing campaigns targeting Ukrainian public organizations, as detailed in a CERT-UA report. This event once again underscores the continuous evolution of cyber threats and the necessity for the public sector to reassess its cybersecurity strategies.

Evaluating cyberattack resilience beyond standard compliance requirements

Thu, 25 Jun 2026 12:03:31 +0300

The modern threat landscape leaves no room for illusions regarding cyber defense. According to the ENISA Threat Landscape 2025 report, 4,875 incidents were recorded and analyzed between July 1, 2024, and June 30, 2025. Most notably, 53.7% of all affected organizations were essential entities subject to the European NIS2 directive. This highlights a systemic issue: strict regulatory pressure and mandatory compliance are not synonymous with actual protection against targeted attacks.

Applying supply chain security principles to AI integrations

Fri, 19 Jun 2026 13:52:35 +0300

Software supply chains are becoming increasingly complex, while dependence on third-party components continues to grow. In 2026, the industry faced a new wave of attacks targeting the npm open-source ecosystem, including the Mini Shai-Hulud campaign and the Miasma incident, during which packages within the @redhat-cloud-services namespace were compromised. Researchers discovered malicious code designed to steal credentials, access tokens, and CI/CD infrastructure secrets. This incident once again demonstrates how vulnerable even large development ecosystems remain and highlights the growing importance of securing AI integrations and software supply chains.

University data breach linked to Oracle PeopleSoft vulnerability

Fri, 12 Jun 2026 06:08:40 +0300

Between May 27 and June 9 of this year, a large-scale attack once again demonstrated the vulnerability of educational institutions. The ShinyHunters group, also known as UNC6240, successfully exploited the critical zero-day vulnerability CVE-2026-35273 in Oracle PeopleSoft software. This occurred even before Oracle published an official advisory on June 10, 2026 (Mandiant, 2026).

This incident exemplifies how cybercriminals leverage the time gap between vulnerability discovery and patch release, jeopardizing confidential data and operational resilience for organizations, particularly within the education sector.

Android Microsoft 365 token theft: Zero Trust and NIS2 implications

Thu, 04 Jun 2026 06:08:38 +0300

Mobile devices have long ceased to be merely auxiliary work tools. Today, they provide full access to corporate email, documents, collaboration platforms, and business applications. As a result, mobile platforms are increasingly becoming attractive targets for cybercriminals. Recent security research has highlighted a vulnerability in certain Microsoft 365 applications for Android that could enable the theft of authentication tokens and unauthorized access to corporate resources.

Although Microsoft has already released security updates to address the issue, the incident reveals a broader challenge: even mature and widely trusted ecosystems can contain vulnerabilities capable of impacting corporate security. For organizations, this serves as another reminder of the importance of a comprehensive approach to mobile security and compliance with modern cybersecurity regulations, including the NIS2 Directive.

Defending critical infrastructure against evolving cyber threat tactics

Tue, 02 Jun 2026 19:41:58 +0300

This year, cybersecurity for Ukrainian hospitals, local government bodies, and FPV operators has become an even higher priority. According to CERT-UA, throughout March-April 2026, an intensification of cyberattacks on local government bodies and communal healthcare institutions, including clinical and emergency medical hospitals, was recorded (cert.gov.ua, moz.gov.ua, zor.gov.ua). These incidents highlight not only an increase in the number of threats but also a shift in attacker tactics, necessitating a review of existing defense strategies.

Automating compliance audits with artificial intelligence

Thu, 28 May 2026 22:52:30 +0300

According to Gartner, by 2026, over 40% of large organizations will leverage AI solutions for automating audit and compliance processes, significantly accelerating the attainment and confirmation of ISO/IEC 27001 and SOC 2 certifications. Traditional audit approaches, relying on manual data collection and document review, are becoming excessively resource-intensive and slow amidst the ever-increasing complexity of IT infrastructure and regulatory requirements.

Challenges of traditional information security audits

The process of preparing for and undergoing audits for compliance with ISO/IEC 27001 and SOC 2 standards is a complex task demanding significant time and resources. The primary challenges include:

Implementing Zero Trust in legacy environments: migration versus adaptation

Tue, 26 May 2026 06:05:19 +0300

Cybersecurity challenges for legacy systems

According to Gartner research, by 2026, over 50% of organizations investing in Zero Trust solutions will not achieve expected results due to focusing solely on new systems and neglecting legacy infrastructure. Legacy systems, often the backbone of critical business operations, pose a significant risk due to the absence of modern authentication, authorization, and network segmentation mechanisms. Amidst the growing number of cyberattacks and strengthening regulatory requirements like NIS2, protecting these systems becomes a priority.

Protocols for data security during employee offboarding by 2026

Mon, 18 May 2026 06:12:10 +0300

According to analytical reports, by 2026, up to 70% of corporate data breaches will be linked to insufficiently effective employee offboarding processes. This highlights the critical need to review and strengthen access management policies after termination. Despite significant investments in perimeter security and threat detection systems, internal risks, particularly those arising from the improper disconnection of former employees from corporate systems, remain one of the most serious vulnerabilities.

Streamlining ISO/IEC 27001 audit processes with AI by 2026

Tue, 12 May 2026 06:08:06 +0300

According to forecasts, by 2026, the volume of data requiring analysis to confirm compliance with cybersecurity standards will increase by 40% compared to the current year. This creates a significant burden on internal teams and external auditors, especially in the context of regular ISO/IEC 27001 compliance checks. The adoption of AI-driven tools is becoming not just an advantage, but a necessity for effective compliance management.

Challenges of Traditional ISO/IEC 27001 Audits

Traditional ISO/IEC 27001 audits are labor-intensive processes that require manual collection, analysis, and verification of vast amounts of information. Key challenges include:

DORA for CIOs: Ensuring Financial System Resilience

Thu, 07 May 2026 16:50:00 +0300

By 2026, the digital landscape of Ukraine has fully integrated into the European legal and technological framework. For CIOs and CTOs in the financial sector and related industries operating with the EU, DORA (Digital Operational Resilience Act) has evolved from a regulatory requirement into a foundation for survival. Under martial law, where energy infrastructure and cybersecurity are critical, DORA compliance is not just about meeting standards—it is about the business's ability to function amidst constant threats.

Adopting Zero Trust architecture for modern ERP security

Tue, 05 May 2026 06:08:34 +0300

According to Microsoft, implementing Zero Trust principles can reduce the risk of successful cyberattacks by 50% or more. For mission-critical systems like ERP, which store financial, operational, and sensitive data, the traditional "trust but verify" approach has proven insufficient. Perimeter security, which assumes trust within internal networks, is no longer effective in the face of hybrid cloud infrastructures, remote work, and ever-increasing threat complexity.

What is Zero Trust and why is it important for ERP?

Zero Trust is a cybersecurity model based on the principle of "never trust, always verify." It requires that every user, device, application, or workload, regardless of its location, be authenticated, authorized, and continuously verified before being granted access to network resources. For ERP systems, which are the central nervous system of any enterprise, this means:

Mitigating 2026 insider threats via AI-enhanced offboarding

Mon, 04 May 2026 06:05:48 +0300

Approximately 60% of corporate data breaches in 2025 were recorded after an employee's termination – while their access formally remained active. Insider threats originating from current or former employees, contractors, or partners remain one of the most complex cybersecurity challenges. With the evolution of hybrid work models and the widespread use of cloud services, traditional offboarding approaches are becoming insufficient for effectively protecting sensitive data. In 2026, companies will increasingly turn to AI-based solutions to automate and enhance employee offboarding processes, minimizing risks.

Zero Trust for Remote Teams: Securing ERP Access

Thu, 30 Apr 2026 14:58:50 +0300

By 2026, remote work has evolved from an option into a strategic necessity for Ukrainian businesses. Amidst martial law, energy infrastructure challenges, and stringent European regulations like NIS2 and DORA, securing ERP access has become a critical pillar of corporate security. Traditional network perimeters have dissolved, and legacy VPN solutions can no longer ensure adequate protection for a workforce operating from diverse locations using both corporate and personal devices.

The Zero Trust model—"never trust, always verify"—is now the only reliable foundation for access infrastructure. Implementing dynamic ERP access control minimizes the risk of unauthorized breaches by restricting user rights to the absolute minimum and continuously validating the context of every request. For CIOs and CTOs, this marks a shift from securing the network to securing specific data and processes, which is essential for modern cybersecurity compliance.

Ensuring NIS2 and ISO/IEC 27001 compliance in cybersecurity

Wed, 29 Apr 2026 06:07:31 +0300

In October 2024, the NIS2 directive became effective in the EU, expanding the scope of cybersecurity requirements to a significantly larger number of sectors than its predecessor. This means companies working with European clients or as part of their supply chains must bring their systems and processes into compliance with the new standards. Simultaneously, the international standard ISO/IEC 27001 remains a fundamental tool for building and maintaining an effective information security management system.

Balancing Security and Agility in Hybrid Infrastructure

Tue, 14 Apr 2026 06:05:43 +0300

When a major bank decided to migrate part of its critical financial operations to the cloud, it faced a dilemma: how to ensure regulatory compliance and a high level of security while retaining the benefits of cloud services' flexibility and scalability? This is a classic scenario illustrating the challenges organizations face when building a hybrid infrastructure. Modern organizations aim to leverage the best aspects of both on-premise solutions and public or private clouds to optimize costs, enhance resilience, and accelerate time-to-market for new products.

Cybersecurity in 2027: shifting from perimeter defense to semantic DLP

Thu, 02 Apr 2026 15:49:43 +0300

Integration of AI systems into critical operational processes requires an immediate shift from reactive defense to proactive risk management to meet the complex threat landscape forming by 2027. As large language models (LLMs) become full-fledged AI agents with access to internal databases, APIs, and ERP systems, the classic security perimeter finally loses its effectiveness. Security executives face a dual challenge: protecting corporate systems from evolving AI attack vectors and ensuring operational resilience amidst a high volume of cyber incidents.

Regulatory demands and the critical first 24 hours of incident response

Mon, 30 Mar 2026 12:36:33 +0200

The first 24 hours after detecting a compromise are the most stressful for any organization. When critical services fail and signs of unauthorized access appear, IT teams naturally want to "put out the fire" quickly: restart servers, restore from backups, and return to normal. However, this approach, focused solely on rapid technical recovery, is now outdated and dangerous for business survival.

Modern incident response is inextricably linked to regulatory requirements. Attempting to immediately erase traces of an intruder destroys digital evidence (forensics), complicates investigations, and prevents timely notification of regulators. This article explores how to synchronize threat containment measures with strict compliance requirements during the first, most critical day after a breach.

Why SIEM and certifications fail to guarantee operational resilience

Mon, 30 Mar 2026 11:42:48 +0200

Organizations are increasingly falling into the "compliance and tools trap," where investments in SIEM platforms and successful certification audits do not translate into real resilience against modern threats. The problem is that executives often view SIEM as a "silver bullet" for automatically solving security issues, and certification as a paper checklist for audits. In reality, a tool without a process creates only a false sense of security if not accompanied by deep operational changes.

Developing a security roadmap and assessment based on NIST CSF 2.0

Fri, 27 Mar 2026 14:36:11 +0200

By 2026, the integration of cyber risks into corporate governance has become a mandatory standard. The updated NIST Cybersecurity Framework (CSF) 2.0 solidified this shift by introducing a new cross-cutting function — Govern. Security has definitively moved beyond being solely a technical task for the IT department, evolving into a strategic process where every decision is mapped to overall corporate risks and regulatory requirements (such as NIS2).

However, in practice, CISOs often find themselves trapped in a cycle of constant "firefighting." Instead of systemic infrastructure development, budgets are spent on fragmented tools, while basic attack vectors remain open. According to the ENISA Threat Landscape 2025 report, phishing remains the primary vector for initial access to corporate systems. The way out of this cycle is through conducting a Gap Analysis and building a roadmap focused on Quick Wins.

Reducing noise in security monitoring with SIEM, SOC, and SOAR

Thu, 26 Mar 2026 15:49:28 +0200

The modern cyber threat landscape demands flawless focus from information security teams. In an era where phishing remains the primary vector for initial access and attacks on digital infrastructure are rapidly evolving, security operations centers (SOC) face not a lack of information, but a critical surplus. Analysts are forced to process thousands of incidents daily, leading to operational paralysis known as alert fatigue.

When a real threat is lost among an avalanche of harmless system logs from security information and event management (SIEM) systems, the effectiveness of even the most expensive infrastructure is negated. To prevent monitoring from drowning in noise, the SOC architecture must be transformed by combining the capabilities of SIEM, security orchestration, automation, and response (SOAR) systems, and proven methodologies for incident structuring.

Protecting legacy systems with Zero Trust: IAP and microsegmentation

Mon, 23 Mar 2026 09:36:30 +0200

IT architects and information security leaders face a complex dilemma. On one hand, regulatory requirements and threat dynamics demand an immediate transition to a Zero Trust architecture. On the other, legacy components—outdated billing systems, monolithic databases, and applications developed long before modern security standards—often remain at the heart of corporate infrastructure. Rewriting them from scratch would halt critical business processes for years. Leaving them as-is exposes the organization to unacceptable risks.

Compliance alignment for NIS2, ISO/IEC 27001, and KSZI standards

Fri, 20 Mar 2026 11:04:48 +0200

By 2026, cybersecurity compliance has ceased to be a mere formality. According to the ENISA Threat Landscape 2025 report, which analyzed 4,875 incidents between July 1, 2024, and June 30, 2025, 53.7% of affected organizations fall into the category of essential entities. This makes aligning corporate systems with the NIS2 directive and modern international standards a critical business task.

However, in practice, Ukrainian companies working with European partners face synchronization challenges. They must simultaneously meet strict EU directives (NIS2), undergo process certification for ISO/IEC 27001, and maintain a comprehensive information protection system (KSZI) for domestic regulators. Attempting to implement these requirements in isolation leads to chaos, redundant audits, and "paper-based security" that fails to stop real cyberattacks.

Cybersecurity discipline: business risks, threat modeling, and design

Thu, 19 Mar 2026 14:42:17 +0200

The updated NIST CSF 2.0 framework has officially established the 'Govern' function as the core of modern cybersecurity. This decision has shifted information security from a purely technical IT department task to a strategic corporate governance imperative. Building security based on a 'firefighting' approach or chaotic procurement of security software licenses is a path to inevitable financial and reputational losses. Effective enterprise cyber resilience requires the integration of threat modeling, architectural controls, and business risks into a single, managed discipline.

Implications of the NIS2 Directive for IT Contractors

Tue, 17 Mar 2026 09:00:00 +0300

The EU NIS2 Directive came into force in October 2024, significantly expanding the scope of entities required to comply with cybersecurity mandates. For Ukrainian companies providing services to EU clients, NIS2 serves as a practical benchmark.

Scope of NIS2

NIS2 covers "essential" and "important" entities across 18 sectors, including energy, transport, healthcare, digital infrastructure, cloud providers, and manufacturing. IT contractors serving these sectors fall under the directive's purview due to supply chain requirements.

Deepfake Phishing: Protecting Corporate Communications in 2026

Wed, 04 Mar 2026 14:40:00 +0200

By 2026, the cybersecurity landscape for enterprises has shifted from mass-market phishing to high-precision, personalized attacks, with generative AI and deepfake technology serving as the primary tools for threat actors. Amidst wartime conditions—where critical infrastructure requires absolute uptime and compliance with NIS2 and DORA standards is essential for European market integration—identity verification in corporate communications has moved from a "best practice" to a critical survival requirement. Today, the voice of your CFO or a video stream of an executive in Zoom is no longer proof of their presence, but a potential gateway for attackers into your internal network.

NIS2 and Supply Chain Security: Auditing IT Contractors

Tue, 17 Feb 2026 16:30:00 +0200

NIS2 and Supply Chain Security: A New Reality for Ukrainian Business

By 2026, the cyber threat landscape for Ukrainian enterprises has shifted from localized incidents to targeted attacks on critical IT infrastructure. With the implementation of the NIS2 directive, resilience requirements have evolved from recommendations into mandatory conditions for integration into the European economic space. For CIOs and CTOs, this means security responsibility now extends far beyond the internal perimeter to every contractor, developer, and cloud service provider. Supply chain security has become a critical survival strategy, where the weakest link of an external partner serves as an entry point for attackers.

Cybersecurity for AI: The emergence of DLP standards by 2026

Tue, 27 Jan 2026 09:52:55 +0200

Rising Risks of Data Leaks in AI Systems

By 2026, over 70% of new AI systems will experience data breaches due to inadequate Data Loss Prevention (DLP) solution integration. Artificial intelligence, integrated into corporate processes, handles vast amounts of sensitive information—from customer personal data to trade secrets and intellectual property. This data is both the fuel for AI and its most vulnerable point. Traditional DLP systems, designed to protect structured data in conventional enterprise systems, often prove ineffective against complex attack vectors targeting AI models and their training datasets.

Zero Trust for legacy systems: replacement or adaptation by 2026?

Fri, 23 Jan 2026 11:27:45 +0200

According to Microsoft, 80% of cyberattacks in 2023 were linked to compromised credentials, highlighting the ineffectiveness of traditional perimeter security models. The Zero Trust concept, which mandates continuous verification of access to resources regardless of their location, is no longer just a recommendation but a necessity. However, its implementation in environments dominated by legacy systems, developed decades ago without consideration for modern threats, presents a significant challenge.

Addressing offboarding as a critical cybersecurity vulnerability

Fri, 16 Jan 2026 15:46:29 +0200

Imagine this scenario: a valuable developer with access to critical repositories and production systems leaves the company. The offboarding procedure is limited to returning a laptop and signing a clearance form. Months later, during an internal audit, it's discovered that their Gitlab account is still active, and access keys to cloud services were never revoked. This isn't a hypothetical situation but a real vulnerability that threatens thousands of companies daily.

Implementing Zero Trust for Hybrid Infrastructure Security

Thu, 08 Jan 2026 09:39:00 +0200

Imagine this scenario: a remote employee connects to the corporate network via VPN. The traditional security model often grants them broad access to internal resources after a single authentication. But what if their device is compromised, or their credentials are stolen? This is precisely where the fundamental weakness of outdated approaches lies, opening the door for attackers to move laterally within the network. In hybrid infrastructures, where data and applications are distributed across on-premises servers, private, and public clouds, this risk is amplified.

Improving Business Process Efficiency Using Electronic Document Management

Wed, 12 Mar 2025 17:03:42 +0300

An industry publication has released an article highlighting the importance of electronic document management (EDM) for modern businesses. The article emphasizes that EDM is an effective tool for combating bureaucracy and significantly speeding up internal and external business processes.

Implementing EDM allows for the automation of routine operations, minimizes the use of paper documents, and ensures transparency at all stages of document handling. According to research, companies that have integrated digital platforms for contract approvals have reduced their decision-making time by an average of 40%. EDM systems provide the ability to track document status in real-time, simplifying control and inter-departmental collaboration.

Strategic Benefits of Automating Legal Workflow Processes

Wed, 26 Feb 2025 15:38:45 +0300

An industry publication recently published an article focusing on automating legal processes and its impact on business efficiency. The article highlights the key advantages of integrating modern technologies into the legal domain.

A primary benefit is the significant acceleration of document approval through the use of electronic signatures and electronic document management systems (EDMS). This allows for contract finalization to be reduced from days or weeks to hours, which is crucial for international agreements. Furthermore, automation ensures a high level of data security via built-in access control mechanisms, blockchain technologies, and end-to-end encryption, protecting information from unauthorized access.

Electronic Signatures: Categorization, Applications, and Advantages

Mon, 27 Nov 2023 06:32:02 +0300

A document management system provider has published an article explaining the specifics of electronic signatures (UAP/QES) in Ukraine. According to the Law of Ukraine "On Electronic Trust Services," an electronic signature is a unique set of encrypted data that identifies a person and gives legal force to documents. It ensures document integrity, confirms the signatory's identity, and protects against forgery.

There are different types of electronic signatures. An Advanced Electronic Signature (AES) is stored on a computer or flash drive and can be created online. A Qualified Electronic Signature (QES) offers a higher level of security, is stored on a secure device (token), and requires personal identification for issuance. It is important to note that as of December 31, 2023, AES can be used instead of QES for most purposes, unless otherwise stipulated by law. A separate category is cloud-based QES, which is stored on a remote server, providing high security and accessibility from any device.

Essential Security Standards for Electronic Document Management Platforms

E-Signature Standards and Advantages for Ukrainian Enterprises

Tue, 26 Feb 2019 15:41:06 +0300

An industry publication recently published an article focusing on the importance and specifics of using electronic signatures (e-signatures) in the context of working with the electronic court system. This topic is relevant for many Ukrainian businesses and professionals, as e-signatures play a key role in digitizing document flow and interaction with state institutions.

According to the Law of Ukraine "On Electronic Trust Services," an electronic signature is electronic data that confirms the identity of the signatory and guarantees the integrity of the signed document. It holds the same legal validity as a handwritten signature, ensuring authenticity, protection against alteration, and the inability to disavow obligations. E-signatures can be obtained from qualified electronic trust service providers by submitting necessary documents, such as a registration card, a copy of a passport, and a taxpayer identification card. The validity period of e-signature keys is typically up to two years.
