A Security Gateway offers the following basic functions:
Message routing: Security Gateway knows about the runtime structure of your Dynatrace environment and routes messages from OneAgents to the correct server endpoints.
Buffering and compression: Security Gateway collects messages from OneAgent instances and builds bulks, which are then sent in compressed form to Dynatrace Server, thereby reducing network overhead.
Authentication: Security Gateway authenticates OneAgent requests (SSL handshake and environment ID authentication).
Entry point for sealed networks: Dynatrace Server clusters often run in protected environments that aren't directly accessible by OneAgent instances running outside of a sealed network. Security Gateway can be used to serve as a single access point for such OneAgent instances. In this way, maintenance overhead is reduced, since you only need to provide access for one well-known Security Gateway (i.e., only a single exception rule in your firewall configuration settings is required).
