About Catalin

I am a freelance auditor and consultant specializing in ISO/IEC 27001, ENS, NIS2, IT Compliance, GRC, risk analysis, and information security.

I offer certification bodies, companies, and consultancies services for audits, ISMS documentation review, gap identification, control evaluation, evidence organization, and progress towards certification or compliance improvement processes.

I can collaborate on ISO 27001 audit projects, Annex A control reviews, statement of applicability, risk analysis, treatment plans, security policies, internal procedures, document management, ENS, NIS2, and evidence preparation.

My differential value lies in combining compliance, auditing, and technical expertise. This allows me to analyze security controls from a dual perspective: regulatory compliance and technical feasibility, understanding how they should be documented, evidenced, and implemented in real cybersecurity architectures.

I have a practical, clear, and results-oriented approach. Understanding the organization's real context, reviewing what exists, detecting what is missing, and proposing concrete actions that can be defended during an audit.

In addition to my experience in IT Compliance and cybersecurity, I have a background in regulated environments, airport security, team supervision, vocational training, and judicial IT expert testimony.
