The Endpoint Security Manager (ESM) Server functions as the connection server that relays information between the ESM components, including the Traps agent, and WildFire. Each ESM Server supports up to 30,000 Traps agents. In a multi-ESM deployment you can also install up to 5 ESM Servers to support up to 150,000 agents.
On a regular basis, the ESM Server retrieves the security policy from the database and distributes it to all Traps agents. Traps agents also relay security event information back to the ESM Server. For information on requirements for the ESM Server, see ESM Server Software Requirements .
