 Pomerium sits between end users and services requiring strong authentication. After verifying identity with your identity provider (IdP), Pomerium uses a configurable policy to decide how to route your user's request and if they are authorized to access the service.

 Pomerium is composed of 4 logical components:
 
 - Proxy Service
+
   - All user traffic flows through the proxy
   - Verifies all requests with Authentication service
   - Directs users to Authentication service to establish session identity
   - Processes policy to determine external/internal route mappings
+
 - Authentication Service
+
   - Handles authentication flow to your IdP as needed
   - Handles identity verification after initial Authentication
   - Establishes user session cookie
   - Stores user OIDC tokens in databroker service
+
 - Authorization Service
+
   - Processes policy to determine permissions for each service
   - Handles authorization check for all user sessions
   - Directs Proxy service to initiate Authentication flow as required
-  - Provides additional security releated headers for upstream services to consume
+  - Provides additional security related headers for upstream services to consume
+
 - Data Broker Service
+
   - Retrieves identity provider related data such as group membership
   - Stores and refreshes identity provider access and refresh tokens
   - Provides streaming authoritative session and identity data to Authorize service

 Pomerium's internal and external component interactions during full authentication from a fresh user are diagramed below.
 
 After initial authentication to provide a session token, only the authorization check interactions occur.
