TL;DR: AI agents now act with real credentials, elevated access and machine-speed autonomy, according to Palo Alto Networks, while 79% of companies already deploy agentic AI and two-thirds report productivity gains. The governance problem is not chatbot oversight but privileged machine identity control, where discovery, scoping and continuous monitoring determine blast radius.
Editorial analysis by NHI Mgmt Group, based on content published by Palo Alto Networks: “Securing AI Agents: Privileged Machine Identities At Unprecedented Scale”.
By the numbers:
- 79% of companies already deploy agentic AI, with two-thirds reporting measurable productivity gains.
Key questions
Q: What breaks when AI agents are treated like standard human users?
A: You lose visibility into effective permissions, expected behaviour, and real blast radius.
Q: Why do AI agents create a larger blast radius than traditional automation?
A: AI agents can chain tools, reuse context, and expand their effective reach during execution, which means one over-permissioned identity can affect multiple systems quickly.
Q: What signals show that an AI agent is operating outside its intended purpose?
A: Look for mismatches across identity, data, model behaviour, posture, and environment.
Practitioner guidance
- Define agents as governed identity subjects Assign each AI agent an owner, an inventory record, and a revocation path before it is allowed to touch production systems.
- Scope agent access to task windows Replace persistent entitlements with task-scoped permissions so elevated access exists only for the exact action sequence the agent must perform.
- Monitor agent behaviour during execution Apply session monitoring and anomaly detection to tool calls, context changes, and unusual action chaining within agent sessions.
Bottom line: AI agents are now best understood as privileged machine identities because they combine credentials, tool access, and autonomous execution.

AI agents are privileged machine identities before they are productivity tools. Once an autonomous system can authenticate, select tools, and act across enterprise systems, the relevant governance unit is identity, not software feature management. That means the security programme has to start from machine identity control, because access scope is what determines whether autonomy becomes useful or dangerous. Practitioners should stop treating agents as a separate category of exception and govern them as part of the non-human identity estate.
A few things that frame the scale:
- 53% of security leaders expect AI to run major portions of their infrastructure autonomously within the next three years, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
A: Organisations should define clear accountability before deployment, not after an agent causes a transaction. The operating model needs named human owners, approval boundaries, audit logging, and escalation paths for disputed or harmful actions. If an AI agent can browse, decide, and transact, governance must specify who authorises the agent, who monitors it, and who responds when the agent exceeds intent.
