TL;DR: AI agents, MCP, ephemeral clients, and API access across trust domains are drawing growing focus, according to Curity’s recent how-to and article set, underscoring how identity controls are being stretched by dynamic, non-human execution paths. The gap is no longer theoretical: governance built for stable credentials and human-paced review cannot fully model runtime agent behaviour.
Editorial analysis by NHI Mgmt Group, based on content published by Curity: “What's New”.
Key questions
Q: What breaks when AI agents and ephemeral clients are governed like stable accounts?
A: The control model breaks because stable-account governance assumes access persists long enough to be reviewed, certified, and later revoked.
Q: Why do short-lived non-human credentials create more governance risk across APIs?
A: Short-lived credentials reduce persistence, but they can increase risk when they cross multiple APIs or trust domains without shared context.
Q: How can teams tell if non-human access is outgrowing their identity model?
A: Look for signs that access decisions are happening faster than review, that tokens are accepted across more systems than governance tracks, and that revocation does not propagate cleanly through the full chain.
Practitioner guidance
- Map ephemeral client lifecycles end to end Document how ephemeral clients are created, scoped, used, and retired across identity providers, APIs, and downstream services.
- Bind runtime authorisation to task scope Limit non-human access to the smallest practical action set for each execution path, and ensure tokens or assertions expire with the task rather than with a generic session timer.
- Rework access review assumptions for agents Stop assuming that review cycles can validate access that may only exist for minutes or seconds.
Bottom line: AI agents and ephemeral clients expose a mismatch between dynamic runtime access and governance models built for stable identities.

Ephemeral trust is now a governance object, not a transport detail. Curity’s topic shows that short-lived clients are changing what identity teams must govern. When access exists only briefly, the control problem is no longer whether a credential can be reviewed later, but whether the access boundary was correct at issuance. That shifts authority from after-the-fact certification toward runtime trust decisions, which many programmes still do not model. Practitioners should treat ephemeral trust as a first-class governance domain.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to the Ultimate Guide to NHIs.
- 64% of valid secrets leaked in 2022 are still valid and exploitable today, proving that detection alone is not enough without automated revocation, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: How should security teams handle delegated access when AI agents act on behalf of customers?
A: Security teams should treat delegated access as a separate governance layer, not as a normal login session. Define what the agent can do, how much value it can move, which approvals are required, and how delegation is revoked. Without those boundaries, the agent inherits more authority than the customer intended and fraud risk expands quickly.
