Active Threat Response – Sophos News


With Sophos Firewall v20 now available for early access, we will be covering some of the top new features every week leading up to launch.

In last week’s article, we covered the new authentication and Azure AD enhancements in Sophos Firewall v20. This week, we’ll have a look at one of the flagship features of this release: Active Threat Response.

Active Threat Response dramatically improves response time.  It essentially extends Synchronized Security to Sophos MDR and XDR analysts – enabling an instant and automated response to active adversaries and threats.

How it works

If an analyst identifies a new threat communicating out to a command and control server, they can push that threat intel to the firewall from Sophos Central via a new threat feed API. The firewall will then start coordinating a defense immediately and automatically, without the need for manual intervention or new firewall rules.

Any host attempting to communicate with the blocked threat will be flagged with a RED Security Heartbeat and be isolated accordingly, preventing any lateral movement and stopping the threat dead in its tracks.  It works equally well regardless of what initially identifies the threat: the analyst, an endpoint, the firewall, or NDR.

This new automated response feature is a game changer for Sophos MDR and XDR customers who use Sophos Firewall.
