Tufin Orchestration Suite
Automates and orchestrates network security policy changes across heterogeneous environments.

Decouple policy from code with a unified, high-performance engine for cloud-native authorization.

Open Policy Agent (OPA) is a CNCF-graduated, open-source policy engine that provides a unified framework for decoupling policy logic from application code. Historically, policy enforcement was siloed within specific applications, but OPA centralizes this via 'Rego', a purpose-built declarative language for specifying policy. The architecture allows OPA to be deployed as a sidecar, host-level daemon, or library, making it highly versatile for Kubernetes admission control, microservices authorization, and CI/CD pipeline guardrails. In the 2026 market landscape, OPA remains the gold standard for Zero Trust architecture, allowing security architects to treat policy as code—complete with unit testing, version control, and automated deployments. By offloading policy decisions to OPA through simple JSON-based API calls, developers can focus on business logic while ensuring strict compliance with organizational standards. Its ability to compile Rego to WebAssembly (Wasm) ensures near-instantaneous policy evaluation, making it suitable for high-throughput environments like financial services and global scale SaaS platforms.

Explore all tools that specialize in kubernetes admission control. This domain focus ensures Open Policy Agent (OPA) delivers optimized results for this specific requirement.
A high-level declarative language specifically designed for querying complex nested JSON structures.
OPA can compile Rego policies into Wasm modules for execution in edge environments or non-Go applications.
An architectural pattern where OPA pulls policy updates and data asynchronously from a remote server.
Automatically records every decision made, including the input, the policy version, and the resulting output.
An optimization where OPA evaluates part of a policy and returns a simplified version to be executed by a database.
A specialized admission controller for Kubernetes that uses OPA to enforce CRD-based policies.
OPA includes a CLI-based test runner to validate policy behavior before deployment.
Install the OPA binary or pull the official Docker image 'openpolicyagent/opa'.
Create a policy file using the Rego language (e.g., authz.rego) defining 'allow' or 'deny' rules.
Define input schemas and mock data for testing your policy logic locally.
Execute 'opa test' to run unit tests against your Rego policies for validation.
Run OPA as a server using 'opa run --server' to expose the HTTP API.
Configure your application or infrastructure to send JSON data to OPA's /v1/data endpoint.
Integrate OPA with Kubernetes using the OPA Gatekeeper controller for cluster-wide enforcement.
Set up a Policy Bundle server to periodically distribute updated policies to OPA instances.
Configure Decision Logging to capture and audit every policy decision made by the engine.
Implement CI/CD pipelines to automatically lint, test, and deploy policies to your production environment.
