Access Sentinel Authorization Server
Access Sentinel is an authorization server built on the ViewDS Directory Server, allowing third-party applications to externalize their access control decisions. Based on XACML v3.0, it provides a policy-based access control solution making applications faster, easier, and safer to use. Fine-grained access control policies, based on roles or attributes, determine whether users can gain access to information, as illustrated below:

The architecture of Access Sentinel Authorization Server is unique because it’s built on ViewDS Directory Server, allowing both identity and policy information to be stored in a single repository. This provides substantial on-prem identity advantages in terms of efficiency, security, and scalability. Access Sentinel also provides a comprehensive policy management interface for creating and maintaining policies.
