I help organizations fix and design PKI and digital trust systems that actually work in production — and pass audits. After 15+ years delivering projects across government, telecom, and financial sectors, I’ve seen the same problems repeatedly: • PKI architectures that are too complex • HSM / key management processes that fail audits • Systems that work in theory but break operationally What I do: → Review and simplify PKI architecture (CA/RA/VA, OCSP/CRL) → Help teams deploy and manage HSMs securely (Utimaco, Thales, nCipher) → Design key ceremonies and audit-ready procedures → Support signing systems (SignServer, timestamping) Typical outcomes: ✔ Faster deployments ✔ Reduced operational risk ✔ Audit-ready environments Now working remotely, I support teams through short, focused consulting engagements. 📩 If you’re running or planning a PKI / HSM project, feel free to reach out.
