About Alfa Oumar

Freelance in OT cybersecurity with a strong IT background, I support industrial companies and organizations operating critical infrastructure in securing their industrial environments.

My expertise lies at the interface between IT and OT: security governance, risk analysis, network segmentation, hardening of industrial architectures, compliance (NIS2, ISO 27001, IEC 62443), and improvement of cyber maturity.

Coming from the IT world, I bring a structured, risk management-oriented vision, while understanding the strong operational constraints of OT environments (availability, safety, legacy systems). My objective is clear: to strengthen the resilience of industrial systems without impacting production.

I intervene in audit, strategic scoping, security roadmap definition, as well as in the management or implementation of technical measures.

If you are looking for a profile capable of bridging the gap between IT teams, industrial teams, and management, with a pragmatic and results-oriented approach, I can assist you.
