Agentic AI security policy is the governance gap teams are missing

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.

NHIMG editorial — based on content published by Zenity: RSA and DC Dispatches: Agentic AI Security Is the Story, Government Policy Needs to Catch Up

By the numbers:

Questions worth separating out

Q: How should organisations govern agentic AI security across the full lifecycle?

A: Organisations should treat agentic AI security as a lifecycle governance issue, not a point control problem.

Q: Why do traditional IAM controls struggle with autonomous AI agents?

A: Traditional IAM controls struggle because they assume stable permissions, stable intent, and a human-paced review cycle.

Q: What breaks when agent-to-agent discovery is left implicit?

A: Implicit discovery breaks trust because one agent may inherit context or delegate work without a clear authentication and authorisation boundary.

Practitioner guidance

  • Map the full agent lifecycle Document provisioning, runtime operation, monitoring, review, and offboarding for every agent class, including homegrown and third-party deployments.
  • Separate entitlement from behaviour controls Use one control set for granted permissions and another for runtime actions, tool calls, and cross-system delegation.
  • Define agent-to-agent trust boundaries Require explicit authentication and scope validation before one agent can pass context or delegate work to another.

What's in the full article

Zenity's full blog post covers the policy detail this analysis intentionally leaves for the source:

  • The specific government initiatives cited across the US, UK, Singapore, and Spain.
  • The author’s meeting-based observations from Washington, DC and RSA 2026.
  • The article's policy architecture proposal for statutory, technical, and industry coordination.
  • The sector examples showing why critical infrastructure adoption is accelerating ahead of governance.

Agentic AI security is becoming an identity governance problem before it becomes a compliance problem. The article shows policy lag across governments, but the deeper issue is that the actor itself is changing faster than governance templates can absorb. When autonomy enters the runtime, the security question shifts from who may access a system to what the system may decide to do next. Practitioner conclusion: treat agentic AI as a new governance class, not a feature extension of workload IAM.

A few things that frame the scale:

  • 92% agree governing AI agents is critical to enterprise security, yet only 44% have implemented any policies to do so, according to AI Agents: The New Attack Surface report.
  • Only 52% of companies can track and audit the data their AI agents access, leaving 48% with a complete blind spot for compliance and breach investigation.

A question worth separating out:

Q: Who is accountable when an AI agent crosses into risky behaviour?

A: Accountability should sit with the team that owns the agent lifecycle and the policy domain that allowed the behaviour. If responsibility is split between platform, security, and business teams without a named owner, incidents become ungovernable. Regulatory and audit expectations increasingly favour clear operational accountability over informal shared ownership.
