Why it matters
AI agent identities are non-human credentials that, if left as static API keys or secrets, become long-lived attack surfaces; enforcing certificate-backed, short-lived identities is a defensive control defenders should weigh for agentic deployments.
Encryption Consulting analyzes the AI agent identity lifecycle across four phases—birth, operation, rotation, and retirement—arguing that vendors like CyberArk, DigiCert, and AppViewX correctly frame agent security as an identity problem but stop at governance. The piece maps eight lifecycle stages to concrete cryptographic controls such as X.509 certificates, automated certificate lifecycle management, and short-lived credentials that expire, rotate, and revoke on schedule.
