Sophos Network Detection and Response: Deep Network Visibility for Stronger Defence

In a threat landscape dominated by stealthy attackers, insider risks, and zero-day exploits, traditional endpoint or perimeter security isn’t enough. Sophos Network Detection and Response (NDR) fills a critical gap by providing deep visibility into east-west network traffic, detecting threats that other tools may miss.

1. Discover Unprotected Devices Sophos NDR helps organisations uncover unprotected or unmanaged devices, including Iot and OT assets, that may silently connect to the network. These endpoints, often overlooked, can become easy targets or entry points for attackers. By identifying them early, IT teams can take action to secure or isolate them.

2. Detect Rogue Assets. With its advanced traffic analysis, Sophos NDR pinpoints unauthorised or rogue devices communicating within your environment. Whether it’s a shadow IT device or a malicious implant, this visibility ensures you're aware of every asset, even those not enrolled in your endpoint security platform.

3. Identify Insider Threats Sophos NDR monitors network traffic patterns and behaviour, offering insight into what “normal” internal communication looks like. Any deviation, such as unusual data movement or unauthorised access attempts, can be flagged, making it a powerful tool for detecting insider threats.

4. Spot Zero-Day Attacks. Unlike signature-based detection, Sophos NDR uses behavioural and packet-based analysis to uncover zero-day exploits. It can detect server-based command-and-control (C2) activity by analysing session data, giving defenders the upper hand even when a vulnerability is unknown or unpatched.

Conclusion: Sophos NDR empowers organisations with the network-level visibility needed to detect threats before they escalate — bridging the gap between endpoint and network security for a truly proactive defence strategy.
