Start with complete discovery, because you cannot govern what you cannot see. Then assign ownership, remove unnecessary privilege, enforce short-lived credentials where possible, and require monitoring and revocation processes for every service account, token, and API key. Cloud governance works only when identity lifecycle controls are applied to automation with the same rigor as user access.
Why This Matters for Security Teams
Non-human identities in cloud environments are not just “service accounts with a different name.” They are the mechanism that lets workloads, automation, pipelines, and APIs act inside production systems, often at machine speed and with broad blast radius. That makes NHI governance a core cloud security discipline, not an inventory exercise. The main risk is cumulative: undocumented identities, static secrets, inherited privileges, and weak ownership combine until a routine task becomes a breach path. NHIs also sit at the intersection of identity, secrets, and infrastructure policy, so gaps often appear in handoffs between teams. NHI lifecycle management guidance in the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is useful here because it frames governance as an ongoing process, not a one-time approval. Current baseline expectations from NIST Cybersecurity Framework 2.0 still apply: identify assets, manage access, detect misuse, and respond quickly. In practice, many security teams encounter NHI sprawl only after a compromised token or over-privileged automation has already moved laterally through the cloud.
