TL;DR: AI agents change access paths faster than manual governance can track, so intent and actual blast radius diverge unless identity, tool, and data context are continuously unified, according to Cyera.

Editorial analysis by NHI Mgmt Group, based on content published by Cyera: “New From Cyera: Actionable Data Risk Insights Across Agents, Alerts, and Retention Policies”.

Key questions

Q: What should security teams do when AI agents need access to tools and data?

A: Security teams should treat AI agents as runtime access actors and separate them from static machine identities.

Q: Why do AI agent runtimes create more governance risk than ordinary service accounts?

A: AI agent runtimes can combine decision-making, tool use, and secret access in one execution path, so a single trust failure can cause data exposure and operational change.

Q: What are the signs that DLP alerts are no longer giving teams useful signal?

A: When the queue is busy but the organisation keeps seeing the same exposure behaviour, the alerts are describing symptoms rather than the underlying workflow.

Practitioner guidance

  • Map live agent anatomy Inventory each agent’s trigger paths, tool connections, and data sources in a single traceable view so access can be compared with approved use cases.
  • Rebuild DLP around repeat patterns Group repeated exposures by data type, destination, and handling pattern so analysts can fix recurring workflows instead of triaging isolated alerts.
  • Treat retention as exposure reduction Target over-retained and stale sensitive data for deletion, archival, quarantine, or delegated review using age signals plus classification context.

Bottom line: AI agents change the control problem by widening access across identities, tools, and data stores faster than manual review cycles can reconcile.

Agent security graphs expose an identity-to-data control gap: The article shows that the meaningful risk is not just whether an agent is authorised, but whether teams can explain its real access path across triggers, tools, and data stores. That is an NHI governance problem because the subject is a non-human executor whose behaviour can expand across workflows faster than manual entitlement review can keep up. Practitioners should treat traceability as a control objective, not a reporting layer.

A few things that frame the scale:

  • Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security, according to the 2026 Infrastructure Identity Survey.
  • 59% of organisations say they lack viable alternatives to standing privileged access for NHIs and AI agents, according to Delinea research.

A question worth separating out:

Q: Should organisations prioritise retention cleanup or agent governance first?

A: If both are immature, start with the area that most directly reduces exposed surface in your current environment. Agent governance controls who or what can reach data now, while retention cleanup removes stale sensitive data that increases breach impact and audit scope. In practice, the highest-risk programmes usually need both, but the first win should be the one that shrinks the widest uncontrolled exposure path.
