Policy Engine
Definition
A policy engine evaluates machine-readable rules for a specific case.
A software component that evaluates machine-readable policies against inputs and context. In an access control architecture, it can assume the PDP role, but the term is broader and not uniformly standardized.
Simply explained
A program compares a request with established rules and determines the appropriate result.
Why it matters in practice
The term helps to design automated processes reliably, measurably, and with clear responsibilities.
Example from business
An engine checks whether an AI workflow is allowed to send data to an external service.
Limits and pitfalls
- Equating policy engine, governance process, and enforcement or changing policies without tests, versioning, and controlled delivery.
Origin & history
Policy engines evolved from rule-based systems and access control.
Use in mid-sized companies
- Possible application: An engine checks whether an AI workflow is allowed to send data to an external service.
