Sentinel is a policy as code framework that enables DevOps teams to apply fine-grained logic-based policy controls against critical services. The Sentinel Playground provides a zero-install development environment for learning and experimenting with policy as code, allowing users of all skill levels to practice writing policies without installing runtime environments. The Playground includes an out-of-box policy example, mock data, and support for parameters and testing, enabling users to quickly prototype functions and rules. With the release of the Playground, customers can now access a core feature set and expand to include Azure and GCP services in future releases.
