  Cerbos is an open-core, language-agnostic, scalable authorization platform
  that decouples access control from application code by externalizing
  fine-grained, context-aware permission decisions into policy-as-code.
  Authorization is expressed in YAML policies supporting RBAC, ABAC, PBAC,
  and ReBAC, evaluated by a stateless Policy Decision Point (PDP) that
  delivers sub-millisecond decisions at scale. The platform consists of the
  open-source Cerbos PDP (Apache 2.0), Cerbos Hub control plane (PAP),
  Cerbos Synapse enrichment layer, and PEP SDKs for Go, Java, JavaScript /
  TypeScript, .NET, PHP, Python, Ruby, and Rust. The PDP exposes both REST
  (port 3592) and gRPC (port 3593) interfaces, an Admin API, and standards-
  compliant OpenID AuthZEN endpoints, with query-plan adapters for Prisma
  and SQLAlchemy.

  description: >-
    The Cerbos PDP REST API is the HTTP/JSON interface for sending
    authorization requests to a running Cerbos Policy Decision Point. It
    exposes CheckResources for evaluating principal-against-resource
    decisions, PlanResources for translating policies into resource-filter
    query plans, and ServerInfo for runtime metadata. An OpenAPI / Swagger
    specification is served by every PDP instance.

  description: >-
    The Cerbos PDP gRPC API exposes the cerbos.svc.v1.CerbosService and
    related management services on port 3593, with server reflection
    enabled. The gRPC interface is the highest-performance way to embed
    Cerbos as a sidecar or in-process service for service-to-service
    authorization.

  description: >-
    Cerbos implements the OpenID AuthZEN authorization API specification,
    exposing standards-compliant single-evaluation, batch-evaluations, and
    well-known metadata endpoints so that any AuthZEN-conformant client or
    Policy Enforcement Point can integrate with Cerbos as the decision
    engine.

    PDP. It is intended for administrative use and is gated by HTTP Basic
    Auth.

    Cerbos Synapse is the enrichment and orchestration component that
    fetches identity, resource, and relationship attributes from external
    systems and translates infrastructure protocols (HTTP, gRPC, GraphQL)
    into Cerbos authorization checks for ReBAC and ABAC scenarios.
