Runtime Enforcement
Evaluating compliance at the exact moment of execution — before an action completes — rather than auditing after the fact.
What it means
Runtime enforcement means that policy validation occurs inline with the action being taken. When an AI agent proposes to approve a purchase order, send a contract, or release a payment, the enforcement layer intercepts the action, validates it against compiled policy rules, and either permits, blocks, or escalates before the downstream system is called.
This is distinct from pre-approval workflows (which require human sign-off before execution) and post-hoc audit (which detects violations after they occur). Runtime enforcement enables the pattern of autonomous execution with deterministic boundaries: the AI acts autonomously within policy, and violations never happen because they are prevented at the gate.
Runtime enforcement is only feasible when the enforcement mechanism is fast enough to sit inline with execution — Corules evaluates policies in under 10 milliseconds, making it practical to call synchronously in any workflow.
Why enterprise executives need to understand this
For COOs and CIOs, runtime enforcement is what converts pre-approval workflows into exception-based oversight. Instead of routing every AI decision through a human reviewer, the enforcement layer handles the routine cases and flags only the edge cases. The approval bottleneck is replaced by an automated gate that operates at the speed of software, not the speed of human review queues.
How Corules implements this
Corules operates as a synchronous validation endpoint. AI agents and workflow automation call /v1/validate with structured context before executing any business action. Corules returns ALLOW, BLOCK, or ESCALATE in milliseconds, with a machine-readable reason and an audit_id. The calling system routes accordingly — completing the action on ALLOW, blocking on BLOCK, or routing to a human queue on ESCALATE.
Frequently Asked Questions
Does runtime enforcement add latency to AI workflows?
Corules evaluates CEL expressions in under 10ms. For most enterprise workflows where the business action itself takes hundreds of milliseconds or seconds, this overhead is negligible. The enforcement call is synchronous but not a practical bottleneck.
What happens if the enforcement service is unavailable?
Corules applies fail-safe defaults: if the enforcement endpoint cannot be reached, the calling workflow should treat the result as ESCALATE, not ALLOW. Corules's SLA guarantees 99.9% availability, and fail-safe default behavior is configurable per tenant.
