Why do AI agents turn NHI governance into an urgent issue?

TL;DR: OWASP’s Agentic Top 10 for 2026 maps the main failure modes in AI agents to identity, tool, memory, and supply-chain risk, showing that most incidents start with overprivileged or exposed non-human identities, not with the model alone, according to OWASP. The governance problem is now operational, because agent security collapses when secret sprawl and implicit trust outpace least-privilege control.

NHIMG editorial — based on research published by Entro Security.

By the numbers:

• 92% agree governing AI agents is critical to enterprise security, yet only 44% have implemented any policies to do so.
• 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 without creating excessive friction?

A: Start by treating each agent as a non-human identity with a defined owner, purpose, and access boundary.

Q: Why do AI agents increase NHI governance risk compared with traditional automation?

A: AI agents can interpret context, choose tools, and chain actions dynamically, which means their behaviour is less predictable than scripted automation.

Q: What is the difference between agent security and NHI security?

A: Agent security focuses on what the AI system says or does at runtime, while NHI security governs the identities, secrets, and permissions that let it act in the first place.

Practitioner guidance

• Inventory every agent-facing NHI Map API keys, service accounts, OAuth tokens, and PATs used by agents across cloud, SaaS, CI/CD, and internal tools.
• Assign distinct identities to agents Stop letting agents ride on human sessions or shared credentials.
• Reduce blast radius for exposed secrets Prioritise rotation and permission narrowing for secrets that multiple agents, microservices, or workloads depend on.

Teams need a control plane that combines identity inventory, privilege review, and behaviour monitoring before usage scales further?
