Runtime Enforcement

Execution-time access control evaluates whether an AI agent action is allowed at the moment the agent attempts to invoke a tool, using the current task context, policy, intent signal, and agent identity as inputs to the access decision.

Runtime access control is the practice of making and enforcing access decisions while a workload is executing, as opposed to at configuration, provisioning, or deployment time.

Access control enforcement for AI agents is the category of security infrastructure that evaluates and enforces access decisions at the agent tool-call layer, at execution time, based on policy, task context, and scoped credentials.

The runtime enforcement layer is the infrastructure component that intercepts agent tool calls at execution time, evaluates access policy, issues scoped credentials, and allows or denies each invocation.

Per-tool authorization decides whether an agent may invoke a specific tool, rather than granting or denying access to an entire server, session, API, or account.

Per-task authorization ties access decisions to the specific task an agent is executing, so that an agent permitted to read customer data for a summarization task is not automatically permitted to do the same for an unrelated task.

Per-call enforcement means that every individual tool invocation by an AI agent is evaluated against access policy at the moment of the call, rather than relying on session-level or configuration-time grants.

Just-for-task access is the principle that an AI agent should receive only the access needed for the specific task it is currently executing—and no more—with credentials that expire when the task ends.

A customer-hosted runtime is an enforcement component deployed within the customer's own infrastructure rather than as a vendor-managed cloud service, ensuring that sensitive tool calls and credentials never leave the customer's environment.

Infrastructure-owned enforcement means that access control policy for AI agent tool calls is owned and operated by the infrastructure or security team, not embedded in agent code or dependent on agent framework behavior.
