Forcepoint DLP ports

Applies to:
  • Forcepoint DLP, v8.5.x, v8.6.x, v8.7.x, v8.8.x, v8.9.x, v9.0, v10.0, v10.1

The most robust and effective implementation of Forcepoint DLP depends on certain ports being open to support the mechanics of the software. The ports for Forcepoint DLP components are 17500–17515 by default. These ports must be left open for all Forcepoint DLP software and hardware configurations.

If you have a security policy in place, exclude these ports from that policy so that Forcepoint DLP can operate properly. If you do not, the policy you have in place may disrupt Forcepoint DLP functionality.

The tables in the rest of this section list the inbound and outbound ports required for each Forcepoint DLP component.

You can lock down or “harden” your security systems once these ports are open.

Important: Forcepoint DLP agents and machines with a policy engine, such as a Forcepoint DLP Server or Content Gateway machine, must have direct connection to the Forcepoint management server. When deployed in a DMZ or behind a firewall, the relevant ports must be allowed.
