Sophos NDR (Network Detection and Response) provides critical visibility into network activity that other products miss. It detects suspicious behaviors that extend beyond firewalls and endpoints, working together with managed endpoints. Sophos NDR detects abnormal traffic flows from unmanaged systems and IoT devices, rogue assets, insider threats, previously unseen zero-day attacks, and unusual patterns deep within the network. Sophos NDR continuously monitors encrypted and unencrypted network traffic to detect suspicious activities indicative of attacker activity, using machine learning, advanced analytics, and rule-based matching techniques.
