Certificates are not optional with Leo D'Arcy
Aired June 22, 2026 | 33 min
Andrew sits down with Leo D'Arcy, cloud solutions architect and PSConfEU speaker, to talk certificates, PKI infrastructure, and why so many organizations get it so spectacularly wrong. Leo shares how a decade of consulting work in remote access solutions pulled him into the world of Active Directory Certificate Services, whether he liked it or not, and how that hands-on experience turned into conference talks and a genuine specialty. The conversation covers the difference between self-signed certs and proper CA infrastructure, why code signing deserves more attention than it gets, and how integrating signing into a CI/CD pipeline is less painful than it sounds. They also get into the "developer-ization" of IT, the underrated value of consulting experience for career growth, and why communicating across teams is just as important as knowing your PowerShell.
