AI agent governance: are your controls keeping up with autonomy?

TL;DR: AI agent governance now has to address agents that make decisions, call APIs, and act across workflows in real time, creating new exposure around access control, observability, and compliance, according to WitnessAI. Governance that treats agents like static software will miss the runtime behaviour that actually drives risk.

NHIMG editorial — based on content published by WitnessAI: AI Agent Governance

By the numbers:

• By 2026, more than half of enterprises will deploy AI agents to automate functions like support, analysis, and content generation.
• 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, inappropriately sharing sensitive data, and revealing access credentials.

Questions worth separating out

Q: How should security teams govern AI agents that can call tools and APIs?

A: Security teams should treat AI agents as governed identities with constrained runtime access, not as ordinary applications.

Q: Why do AI agents create more governance risk than static automation?

A: AI agents create more governance risk because they can choose actions at runtime, change tool usage based on context, and cross workflow boundaries without a human step between every decision.

Q: What breaks when AI agent access is reviewed like normal application access?

A: What breaks is the assumption that a single access review can describe behaviour that changes every time the agent runs.

Practitioner guidance

• Define agent-specific access boundaries Map every agent to the exact data sources, APIs, and actions it may use, then review those entitlements as runtime permissions rather than generic application access.
• Inventory and retire agents as governed identities Track each agent from creation to decommissioning, including ownership, approved tools, and retirement criteria, so abandoned agents do not retain access after their business purpose ends.
• Require decision logging before production use Capture prompts, tool calls, policy outcomes, and downstream actions so investigators can reconstruct what the agent did and whether it stayed within its intended scope.
