Release Notes for Styra DAS

This page describes the release notes for Styra DAS delivered in October 2021.

Release Summary​

Styra is built on the Open Policy Agent (OPA), a popular and widely deployed open source project developed by the founders of Styra. With primary credibility for the underlying technology, the Styra team and technology are both proven in production across verticals. Styra enables enterprises to define, enforce, validate, and continually monitor security, compliance and operational policies across the cloud-native application stack. Styra has reinvented the authorization solutions to mitigate customer risk, and reinforce commitment to trust and transparency in safeguarding customers’ data. Styra’s Declarative Authorization Service (DAS) is a sophisticated management plane that provides context-based guardrails, built from a graphical policy library to mitigate risk, reduce human error and accelerate development. Styra makes it possible for enterprises to implement policy-as-code controls and to prove their effectiveness to both internal and external security and compliance audiences.
