TL;DR: Agentic AI security emerged as the defining cyber risk at RSA 2026, while government policy remains fragmented across NIST, the UK, Singapore, and Spain, according to Zenity. The gap is no longer about awareness, but about lifecycle-based governance that can keep pace with autonomous systems before critical infrastructure dependency hardens.

Editorial analysis by NHI Mgmt Group, based on content published by Zenity: “RSA and DC Dispatches: Agentic AI Security Is the Story, Government Policy Needs to Catch Up”.

Key questions

Q: How should security teams govern agentic AI as it moves into production?

A: Security teams should govern agentic AI as a class of non-human identity, not as a generic application feature.

Q: Why do static IAM policies struggle with autonomous AI agents?

A: Static policies assume the access pattern is known before execution and remains stable long enough to review.

Q: What are the signs that AI governance is too fragmented to support scale?

A: Common signs include duplicated governance tools, inconsistent policies across business units, and teams managing AI or data controls in isolation.

Practitioner guidance

  • Map the full agent lifecycle Identify where agentic AI is created, configured, deployed, monitored, changed, and retired across cloud, endpoint, and local environments, then assign control ownership to each stage.
  • Separate runtime trust from provisioning trust Document which authorisation decisions are made before execution and which must be re-evaluated during execution when agent behaviour, tools, or contexts change.
  • Inventory inter-agent trust paths List every place where one agent can discover, authenticate, or invoke another agent, then record the policy basis for that relationship and the environment it spans.

Bottom line: Agentic AI security is not just a policy debate. It is a lifecycle governance problem that crosses development, deployment, runtime monitoring, and retirement.

Lifecycle governance is the missing control plane for agentic AI. The article makes clear that governments are producing partial guidance, but no comprehensive framework yet spans the full agent lifecycle across environments. That matters because agentic systems do not stay inside a single control boundary long enough for siloed policy to be sufficient. The implication is that identity governance for agents must be designed as an end-to-end lifecycle discipline, not a collection of stage-specific checks.

A few things that frame the scale:

  • Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption, according to the 2026 Infrastructure Identity Survey.

A question worth separating out:

Q: When should organisations prioritise lifecycle governance over isolated AI controls?

A: Organisations should prioritise lifecycle governance as soon as agents can act across more than one environment or influence more than one business process. At that point, isolated controls become difficult to reconcile and can leave gaps between deployment, runtime, and oversight. Lifecycle governance gives the programme a single model for change, accountability, and policy drift.
