What Sean writes about
CertLocker content is written from the perspective of teams operating messy infrastructure rather than from a generic security-marketing angle. The focus is certificates that expire at bad times, ACME workflows that renew but do not deploy, shared secrets without version history, standing SSH and RDP access, AI agents touching credentials, and audit questions that arrive after the fact.
