Expert Leadership in Digital Trust

Paul van Brouwershaven brings unparalleled expertise in PKI, cryptography, and regulatory compliance. As a recognized global authority, he shapes international standards while delivering practical solutions for the world’s most demanding trust infrastructures.

Paul actively shapes international policy and best practice:

Chair, PKI Consortium: driving global awareness and adoption of trustworthy PKI.
Chair, PQC Working Group: organising the annual Post-Quantum Cryptography Conference and guiding crypto-agility adoption.
Former Vice-Chair, CA/Browser Forum: managing the rules that govern TLS, S/MIME, CodeSigning, and consumer trust signals.

Paul’s work bridges regulators, auditors, and practitioners so compliance becomes a catalyst for resilience rather than a burden. He converts complex governance requirements from bodies such as IETF, ETSI, eIDAS, WebTrust, and the CA/Browser Forum into practical operating models.
