HashiCorp Terraform has integrated with OPA-founder Styra to allow users to validate Terraform infrastructure as code using Open Policy Agent (OPA). This integration aims to help organizations achieve their security and compliance goals by enabling policy as code, which allows teams to define security and compliance requirements within the code. The integration of HashiCorp Terraform with Styra Declarative Authorization Service (DAS) provides detailed policy control over Terraform plans, mitigating risks, reducing human error, and accelerating development. Users can leverage pre-built policies or create custom ones using Rego, the OPA policy language. This integration helps enforce any type of rules on Terraform resources and user actions across multiple workspaces.
