About Open Policy Agent (OPA)

Open Policy Agent is a policy engine that streamlines policy management across a technology stack. It is a general-purpose policy engine that unifies policy enforcement across the stack. It provides a high-level declarative language for specifying policy for a wide range of use cases. It can be used to enforce policies in applications, proxies, Kubernetes, CI/CD pipelines, API gateways, and more. Security and platform teams centrally manage shared policies while developer teams extend them within the policy system. Open Policy Agent is a Cloud Native Computing Foundation Graduated project.

Products

Rego: A domain-specific policy language built for speed, operating on pre-loaded, in-memory data.

Used for

Controlling which Kubernetes resources can be created in a cluster.
Enforcing policies over which tools an AI agent can call and what parameters are permitted.

Who it is for

Security & platform teams who centrally manage shared policies.
Developer teams who extend policies as needed.

How to evaluate Cloud Security & CSPM

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Open Policy Agent (OPA). It comes from our Cloud Security Posture Management (CSPM) buyer guide.

25%

Risk Prioritization & Attack-Path Analysis

Context graph that correlates misconfiguration, internet reachability, identity/permissions, vulnerabilities, secrets, and data sensitivity into ranked attack paths to crown-jewel assets; toxic-combination detection; quality of the “fix these 10” output versus raw finding volume; false-positive rate in your own accounts

20%

Coverage Model: Agentless Breadth vs. Runtime Depth

Agentless snapshot/API scanning for fast 100%-estate visibility versus agent/eBPF runtime for in-production threat detection (CDR); container, serverless, and Kubernetes (KSPM) coverage; how the two models combine without double-counting; performance impact and deployment friction

20%

Multi-Cloud & Platform Consolidation (CNAPP)

Depth and parity across AWS, Azure, GCP, OCI, and Kubernetes from one console; how many of CSPM, CIEM, CWPP, DSPM, KSPM, and code/IaC security are genuinely unified on one data model versus bolted-on acquisitions; single policy and one risk score across domains

15%

Identity & Entitlements (CIEM)

Effective-permission analysis across human and machine identities, cross-account and federated role mapping, detection of unused and over-privileged entitlements, least-privilege right-sizing recommendations, and privilege escalation / lateral-movement path discovery

10%

Remediation, Automation & Developer Workflow

Guided and auto-remediation, IaC and pull-request fixes (shift-left to code), guardrails that prevent drift, ticketing/SOAR integration, ownership routing to the right team, and API/Terraform coverage for security-as-code

10%

Compliance, Reporting & SOC Integration

Out-of-the-box frameworks (CIS, PCI DSS, HIPAA, SOC 2, FedRAMP, NIST) with custom policy authoring, audit-ready evidence and drift history, RBAC/SSO on the console, and clean export of correlated cloud risk into the SIEM/SOC rather than a siloed dashboard
