Description

With over 20 years of expertise in Industrial Cybersecurity, I am a trusted expert in securing operational technologies (OT) and critical infrastructure. My experience spans deep technical implementations, as well as strategic security architecture and governance, enabling me to support not only engineering teams but also executive leadership in making informed, risk-based decisions.

I bring a unique blend of hands-on experience with SCADA, PLC, and industrial networks, combined with a comprehensive understanding of security frameworks, compliance, and business continuity in highly regulated environments.

🔧 Expertise Highlights:

Cybersecurity Architecture & Governance: Design and implementation of security procedures, frameworks, and compliance programs across IT/OT environments, aligned with ISA/IEC 62443, NIST 800-82, ISO/IEC 27000, NERC CIP, and COBIT.

Industrial Security Operations: Extensive hands-on experience in SCADA, PLC, MESH network security, physical security assessments, and vulnerability testing.

Risk Management & Executive Advisory: Proven capability in conducting risk assessments, Business Impact Analysis (BIA), and disaster recovery planning, with the ability to advise CISOs, CTOs, and board-level stakeholders.

Security Engineering & Threat Detection: Strong background in CIS hardening, patch management, social engineering simulations, OWASP testing, and advanced endpoint & SIEM solutions (McAfee, SolarWinds).

Regulatory Compliance & Classified Environments: Security verification for Slovak National Security Authority (NSA) for confidential environments.

I am passionate about building secure, resilient industrial ecosystems, and helping organizations confidently align their cybersecurity posture with both technical realities and business priorities.

Let’s connect if you’re focused on defending critical infrastructure or transforming your OT/ICS security strategy.
