What is the difference between NDR and an IDS or IPS?
An IDS or IPS matches traffic against known attack patterns; NDRNDR: network detection and response. Security monitoring that watches the traffic between devices and raises an alert when one behaves like an attacker. looks at how each device behaves over time. An IDS (intrusion detection system) raises an alert when traffic matches a signature, such as a known exploit or malware pattern. An IPS (intrusion prevention system) does the same and can drop the matching traffic, usually as part of a firewall. Both are good at known threats and weaker when an attacker uses legitimate tools or a new variant with no signature. NDR (network detection and response) learns what is normal for each host and flags deviations: new peers, regular call-outs, scanning, unusual volumes. Many companies run both. NetSenX is an NDR: it scores host behaviour, explains each alert in plain language, and does not drop or block traffic, so it can run beside your firewall's IPS without changing your network path.
