Styra Documentation

Welcome to the Styra documentation site. Here you will find information on how to use and configure the Enterprise OPA Platform and all of its components.

The Enterprise OPA Platform includes:

  • Enterprise OPA, a performance optimized, drop-in replacement for OPA
  • Declarative Authorization Service (Styra DAS), a centralized management solution providing the control plane, policy lifecycle management, and policy governance, and
  • Developer tooling along with services and support.

Organized by platform components, these docs will show you how to use the Enterprise OPA Platform to its full potential and get your work done.

Styra DAS

Styra Declarative Authorization Service (DAS) is built on top of the open-source project Open Policy Agent (OPA) and provides authorization through policy management across the cloud-native ecosystem.

Enterprise OPA

Enterprise OPA is an enterprise-grade drop-in replacement for the Open Policy Agent (OPA) that offers:

  • Datasource integrations: Connect quickly to your Kafka, LDAP, DynamoDB, S3, SQL database, MongoDB and Vault without needing to write or manage your own plugins.
  • Secrets manager integration: Connect to HashiCorp Vault to securely use http.send.
  • Logging integrations: Send your authorization decision logs to Splunk or Kafka.
  • Live impact analysis: Check to see if your new policies impact production before they are merged.
  • Lower costs: Use cheaper cloud infrastructure because Enterprise OPA uses 10x less memory and 40% less CPU than OPA.

Regal aims to:

  • Identify common mistakes, bugs and inefficiencies in Rego policies, and suggest better approaches
  • Provide advice on best practices, coding style, and tooling
  • Allow users, teams and organizations to enforce custom rules on their policy code
