Yes, when the agent can choose actions, tools, or execution timing at runtime. Standard automation is bounded by scripts and predefined workflows, while agentic behaviour can change the privilege profile during execution. PAM should reflect that distinction before approvals and access policies are set.
Why This Matters for Security Teams
AI agents should be treated differently from standard automation because PAM is not only about whether a task is allowed, but also about whether the workload can change its own path, timing, and tool use mid-execution. That autonomy makes static approval models brittle. Guidance from the OWASP Agentic AI Top 10 and the NIST AI Risk Management Framework both point to runtime risk, not just pre-issued privilege, as the real control problem.
For standard automation, PAM can usually assume bounded scripts, fixed identities, and predictable call chains. For agents, those assumptions fail. An agent may decide to inspect data, chain tools, retry with different parameters, or request access to a new system based on current context. That means the privilege profile can expand during a single run unless controls are evaluated at request time. In practice, many security teams discover this only after an agent has already accessed a system it was never explicitly intended to reach, rather than through intentional design.
How It Works in Practice
Effective PAM for AI agents starts by treating the agent as a workload with a cryptographic identity, not as a human user with a long-lived role. Current guidance suggests using workload identity, short-lived tokens, and policy decisions that happen at runtime. Standards like CSA MAESTRO agentic AI threat modeling framework and MITRE ATLAS adversarial AI threat matrix are useful because they frame the agent as an active attacker surface, not a passive script.
In operational terms, PAM design should shift from standing privilege to task-scoped privilege:
- Issue just-in-time credentials with short TTLs, then revoke them automatically when the task completes.
- Bind access to workload identity, such as SPIFFE-style identities or OIDC-backed service tokens, so the system knows what the agent is, not just what secret it holds.
- Evaluate policy at request time with context, using policy-as-code rather than fixed allowlists built for human roles.
- Separate tool permissions from data permissions so one successful action does not imply broad lateral access.
NHI Management Group research on the OWASP Agentic Applications Top 10 reinforces this distinction: agentic systems create new risk because actions can be assembled dynamically, not because they simply execute faster than humans. That matters in real environments where an agent can call APIs, open tickets, query data, and launch follow-on actions without a fixed script.
The same logic applies to secrets handling. NHI security research in The State of Secrets in AppSec shows how difficult it is to control leaked or fragmented secrets once they exist. For agents, the control objective is to avoid giving them durable secrets in the first place. These controls tend to break down when agents are embedded in legacy automation stacks that assume human approval flows because the runtime decision point is already too late.
Common Variations and Edge Cases
Tighter agent PAM usually increases operational overhead, requiring organisations to balance security assurance against latency, orchestration complexity, and developer friction. That tradeoff is real, especially where teams want one control model for both scripts and agents. Best practice is evolving, and there is no universal standard for this yet.
One common edge case is a hybrid workflow where a script launches an agent for only part of the process. In those cases, the script may still be predictable, but the agent must be isolated with narrower scope and shorter-lived access. Another case is tool-rich agents that need temporary access to multiple systems. The safe pattern is not broad role assignment. It is task decomposition, with each step receiving only the minimum privilege needed for that specific action.
Another important exception is human-in-the-loop approval. That is useful for high-risk actions, but it does not replace technical enforcement. An approval before execution does not help if the agent can later decide to use a different tool path. NHI Management Group’s reporting on the AI agents attack surface shows why this matters: once an agent is operating outside intended scope, visibility and containment are often weaker than teams expect. For that reason, PAM for agents should be designed around runtime containment, not just approval gates.
In environments with regulated data, multi-agent workflows, or autonomous remediation loops, the guidance breaks down fastest when teams rely on static RBAC to govern dynamic behaviour. That is where privileged access stops being a scheduling problem and becomes a control-plane problem.
