Detect Suspicious Behaviors That Extend Beyond Your Firewalls and Endpoints

Zero Trust illustration




Sophos NDR works together with your managed endpoints and firewalls to monitor network activity for suspicious and malicious patterns they cannot see. It 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.

Download Solution Brief

Sophos NDR detects a range of network behaviors, making it an effective solution for identifying:

Home illustration

Unprotected Devices

Identify legitimate devices that aren't protected and could be used as entry points, including IoT and OT assets.

Client isolation icon

Rogue Assets

Pinpoint unauthorized and potentially malicious devices communicating across a network.

Networks and Endpoints icon

Insider Threats

Gain visibility to network traffic flows and “normal” data movement from inside an organization.

Zero-Day Attacks

Detect server command-and-control (C2) attempts based on patterns found in session packets.

Early Detection and Automatic Response

Sophos cross-product automation between NDR, XDR, MDR, and Firewall provides immediate response to stop active threats dead in their tracks.


How it works: Sophos NDR monitors traffic deep within the network, sending suspicious activity to Sophos Central’s data lake for further analysis. In the event an active threat or adversary is identified, analysts can immediately push a threat feed to Sophos Firewall that can coordinate an Active Threat Response to isolate and block malicious activity automatically in real-time.

5 Independent Detection Engines That Work in Real-Time


NDR Detection Engines

Data Detection Engine 

Extensible query engine uses a deep learning prediction model to analyze encrypted traffic and identify patterns across unrelated network flows.

Deep Packet Inspection

Uses known indicators of compromise to identify threat actors and malicious tactics, techniques, and procedures across encrypted and unencrypted network traffic.

Encrypted Payload Analysis

Detects zero-day C2 servers and new variants of malware families based on patterns found in the session size, direction, and interarrival times.

Domain Generation Algorithm

Identifies dynamic domain generation technology used by malware to avoid detection.

Session Risk Analytics

Powerful logic engine utilizes rules that send alerts based on session-based risk factors.
