Founder of Mac Mathews Consulting

Security auditorANSSI-trainedStormshield administratorSecure links specialistApplied cryptographySovereign infrastructure

More than fifteen years in operational environments with the highest security requirements, where confidentiality, resilience and discretion are never optional.

An information security auditor trained by ANSSI, the French national cybersecurity agency, a Stormshield administrator and a specialist in secure communication links and applied cryptography — I worked on sensitive transmission systems long before turning to web applications and sovereign managed hosting.

Today, I bring that operational rigour to non-profits, small businesses and independent professionals: secure architecture, clean and documented code, controlled hosting and long-term support. No offshore subcontracting.
