No. Human reviews focus on role, business need, and employment status, while agent reviews must also cover tool scope, credential inheritance, and downstream action paths. The review object is not just the agent itself but the full execution chain it can initiate. That distinction matters because agent behaviour can change faster than a standard recertification cadence can capture.
Why This Matters for Security Teams
Agent access reviews cannot be treated like human recertification because the risk surface is not the person, it is the autonomous execution chain. A human review asks whether employment status and job need still justify access. An agent review has to ask whether the agent can still invoke tools, inherit secrets, chain actions, and reach systems that were never meant to be traversed in one run.
That distinction is central in guidance from the OWASP Agentic AI Top 10 and NHI research from Ultimate Guide to NHIs, which shows that only 5.7% of organisations have full visibility into their service accounts. That visibility gap becomes more dangerous when agents operate with delegated tools and short-lived credentials that can change by task, not by quarter.
Security teams often miss that agent reviews are really a review of what the agent can do next, not what it did last month. In practice, many security teams encounter excessive agent reach only after a tool chain has already been abused, rather than through intentional recertification.
How It Works in Practice
Effective agent reviews start with the workload identity, then expand to the permissions, secrets, and downstream actions attached to that identity. The key question is not “does this agent still belong to a role” but “what can this agent prove, request, and trigger right now?” Current guidance suggests treating the review object as a bundle: identity, tool scope, credential inheritance, policy path, and human override path.
Practically, this means reviewing:
- Which tools, APIs, and connectors the agent can call.
- Whether credentials are static, inherited, or issued just-in-time for a task.
- What data the agent can read, transform, forward, or exfiltrate through chained actions.
- Which policies are evaluated at request time, not only at onboarding.
- Whether the agent has boundaries that prevent lateral movement into adjacent systems.
That approach aligns with NIST AI Risk Management Framework principles around governance and measurement, and with NHI Lifecycle Management Guide recommendations for lifecycle-bound access and revocation. It also fits the implementation direction of CSA MAESTRO agentic AI threat modeling framework, which pushes teams to model agent behaviour as a sequence of actions rather than a static account record.
In mature environments, the review cadence is event-driven as well as periodic: new tools, new prompts, elevated scopes, model swaps, and new downstream data paths all trigger reassessment. These controls tend to break down when agents are embedded in CI/CD or orchestration pipelines because access changes faster than manual recertification can keep up.
Common Variations and Edge Cases
Tighter agent review controls often increase operational overhead, so organisations have to balance faster delivery against stronger containment. That tradeoff becomes sharper for autonomous workflows that support production operations, customer interactions, or developer tooling.
There is no universal standard for how often an agent should be recertified, but best practice is evolving toward risk-tiered review. High-impact agents should be reviewed more often, especially when they can access production systems, regenerate secrets, or invoke external services. Lower-risk agents may be reviewed on a longer cadence if their tool scope is tightly bounded and their credentials are ephemeral.
Common edge cases include:
- Agents that share a service account, which makes ownership and accountability ambiguous.
- Agents that inherit human credentials through delegation, which obscures the actual blast radius.
- Multi-agent systems where one agent can authorize another, creating indirect privilege expansion.
- Agents with temporary task scopes that still expose durable downstream data paths.
For organisations comparing modern agent governance with legacy access models, the strongest signal is whether reviews follow 52 NHI Breaches Analysis style lessons about non-human compromise and whether those lessons are operationalised in policy. Emerging practice is also converging with OWASP Non-Human Identity Top 10 and the OWASP Top 10 for Agentic Applications 2026, but there is no single recertification template that fits every agent architecture.
