Sophos XG Firewall is the only network security solution that is able to fully identify the source of an infection on your network and automatically limit access to other network resources in response. This is made possible with our unique Sophos Security Heartbeat™ that shares telemetry and health status between Sophos endpoints and your firewall.

XG Firewall not only monitors host network activity, but also receives health status directly from your endpoints so you have constant visibility into the health of your entire network.

XG Firewall instantly alerts you to compromised systems on your network with full details including the IP address, the user, and the process, so you're not left digging for information.

XG Firewall uniquely integrates the health of connected hosts into your firewall rules, enabling you to automatically limit access to sensitive network resources from any compromised system until it's cleaned up.
