As senior cybersecurity practitioner and founder of steadysec.eu. I act as the dedicated, fractional security owner that small and medium enterprises need, providing the high-level expertise of a full-time executive without the full-time overhead.
Throughout my career, I have operated across the entire lifecycle of cyber defense—from launching offensive operations as an ethical hacker to managing defenses for a global retailer and advising international bodies like the EU, UNDP, and OSCE. I do not just hand over a report of your gaps; I step in to close them, generate enterprise-ready evidence, and establish steady, long-term resilience.

Core Expertise & Services
  • Governance, Risk & Compliance (GRC): End-to-end guidance for ISO 27001 Readiness, NIS2 Compliance, and Cyber Resilience Act (CRA) tracking.
  • Technical Testing & Offensive Security: Expert-level Web & API Pentesting, AI / LLM Pentesting, Active Directory Assessments, and realistic phishing simulations.
  • Strategic Leadership: Acting as a retained vCISO, delivering risk management, vendor decisions, and board-level reporting.
  • Capacity Building: Interactive training, workshops, and high-stakes tabletop crisis simulations.

Top Professional Credentials
  • CISSP (ISC2) | ISO 27001 Lead Auditor | SecurityX (CompTIA).
  • Vetted Institutional Expert: Enlisted on the EU CyberNet Roster, EEAS, UNDP, and OSCE expert capacities.

Flexible Working Arrangements
Every business moves at its own pace, which is why I offer highly versatile engagement models:
  • Remote-First Collaboration: Seamlessly structured for 100% remote delivery across Europe.
  • Engagement Modality: Available for fixed-scope project sprints (pentests, audits) or a predictable, month-to-month retained security partner agreement.
  • B2B Contracting: Smooth corporate onboarding and direct B2B contracting through my legal Czech entity, Steady Security s.r.o..
