Human IAM matured over decades. Machine identities grew faster than ownership, inventory, and audit models could follow.
Every cloud account, CI pipeline, Kubernetes cluster, and SaaS integration adds service accounts, API keys, OAuth applications, and automation tokens. Security teams inherit this sprawl through mergers, platform shifts, and developer self-service. Most organizations can list human users in Okta or Entra ID. Far fewer can name the owner of a three-year-old IAM role attached to a decommissioned microservice.
Entro published telemetry from enterprise customers in H1 2025 analyzing more than 27 million non-human identities. The NHI-to-human ratio reached 144:1, up from 92:1 the prior year. CyberArk public research cites machine identities outnumbering humans by up to 45:1 in large environments. Oasis Security positions the category as NHIs across hybrid cloud with agentic workloads accelerating creation further.
The failure mode is consistent: unknown owner, excessive privilege, stale credential, no evidence trail when auditors or incident responders ask who approved access and what breaks if the identity is revoked. Sentyn addresses the ownership and evidence layer read-only. We do not claim behavioral detection, autonomous remediation, or secrets vaulting.
