Scalable cloud-based endpoint security system
A scalable cloud-based endpoint security system facilitates a security policy on a plurality of endpoints. Configuration data or commands for implementing a security policy are entered via a web browser of an administrative client device and received at a cloud server. An API server generates a message to a queue of a publication/subscription server that publishes the messages from the queue to one or more subscribing communication servers. A communication server sends the message to an endpoint targeted by the message via a persistent connection that the communication server maintains with the endpoint. In response to the message, the endpoint establishes a connection to the API server. The API server then distributes the configuration data or commands to the endpoint.

sending, by the communication server, the connection request message to the identified endpoint via a persistent connection;
receiving by the API server, a connection request from the identified endpoint in response to the identified endpoint receiving the connection request message;
establishing a temporary connection between the API server and the identified endpoint in response to the request; and
communicating, by the API server, the command to the identified endpoint over the temporary connection.
