TL;DR: Agentic AI changes application security by introducing autonomous systems that use legitimate credentials, act at machine speed, and create behavioural risk that static controls cannot contain, according to Apiiro. The governance problem is no longer just access management; it is continuous containment of non-human identities whose actions can drift from intent in runtime.
Editorial analysis by NHI Mgmt Group, based on content published by Apiiro: “Best practices for integrating agentic AI into app security”.
Key questions
Q: Where do agentic AI controls fail in practice when agents have legitimate access?
A: They fail when security assumes legitimacy equals safety.
Q: Why do autonomous agents require stronger accountability than ordinary non-human identities?
A: Because an agent can make runtime decisions and execute actions without a human clicking every step, the organisation must bind the identity to a clear owner and a bounded purpose.
Q: How can security teams tell whether an agentic AI system is drifting from intent?
A: Look for behavioural drift, not just technical errors.
Practitioner guidance
- Define zones of intent for each autonomous agent Set explicit action boundaries for every agent, including which systems it can touch, which workflows it can trigger, and which outcomes require human approval.
- Enforce just-in-time credentials for agent actions Replace persistent access with time-bound credentials that are issued only when a task requires them, then revoke them as soon as the task ends.
- Instrument agent telemetry from prompt to output Collect logs for token usage, tool calls, decision chains, and resulting system changes so security teams can reconstruct behaviour end to end.
Bottom line: Agentic AI introduces a control problem that static perimeter and vulnerability tools do not solve because autonomous systems can act inside trusted environments with legitimate access.

Behavioural context is becoming the new perimeter: autonomous systems erode the value of perimeter-first security because they operate inside trusted environments with valid access. That means the real governance question is no longer whether an agent can connect, but whether its actions remain within intent as conditions change. Practitioners should treat behavioural drift as a first-class control failure, not a monitoring exception.
A few things that frame the scale:
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What is the difference between static appsec scanning and behaviour-based governance for agents?
A: Static scanning looks for flaws in code or configuration before deployment, while behaviour-based governance evaluates what the agent actually does after deployment. For autonomous systems, the second control is decisive because risk often appears only when the agent reasons, adapts, and executes inside a live environment.
