Intrusion Prevention, supplied & supported
Plenty of attacks never come through the front door as an obvious email or dodgy download. They arrive as malicious traffic probing your network for a weakness. Intrusion Prevention on your Sophos firewall inspects that traffic as it passes and matches it against a constantly updated library of known attack patterns, so exploits and reconnaissance attempts are blocked at the boundary rather than deep inside your systems.
We tune the intrusion prevention policies to suit how your business actually works, so genuine traffic flows freely while suspicious activity is stopped. Signatures update automatically as new threats appear, and because the inspection happens on the firewall itself there is nothing for your team to install or manage. It simply sits in the background, quietly turning away the attacks you never see.

0330 333 8175A basic rule decides which connections are allowed. Intrusion prevention looks inside the traffic that is allowed and blocks it if the content matches a known attack, catching threats that would otherwise slip through.
On a correctly sized Sophos XGS appliance the impact is minimal. The inspection is hardware-accelerated, and part of our job when sizing the firewall is making sure it has the capacity to inspect at your connection speed.
Yes. Sophos updates the signature library continuously as new threats are discovered, and those updates apply automatically so your protection keeps pace without any action from you.
