NDR vs EDR

NDR and EDR are emerging terminologies in cybersecurity. What are these tools used for? Does one replace the other?

In this article, we will clarify the role of each.

NDR (Network Detection and Response)

NDRs are the ultimate intrusion detection technology. They are connected to the network entrance, usually on the network's main switch (or core-switch). They intercept all traffic entering and leaving the network and analyze it for signs of attacks or suspicious behavior. Any computer communicating in the network is automatically discovered by the NDR, giving it 360-degree visibility into the computer network.

NDRs look for signatures (or attack patterns) of attacks in network traffic. They use AI to detect deviations in behavior that are indicative of a cyberattack.

NDRs can automatically block attacks (via firewall, etc.).

EDR (Endpoint Detection and Response)

Like antivirus, EDR is a computer protection technology. The fundamental difference with antivirus is that EDR can detect malicious tools, but also other types of activities that take place on a computer.

The EDR will also collect and provide information necessary for investigation (forensic analysis) in case of identified malicious activity. As we can see, the EDR goes beyond the actions that a traditional antivirus takes.

EDR and NDR are complementary

To protect yourself from today's cyberattacks, you need to protect every computer on the network (via an EDR), as well as the network perimeter (via an NDR). This 2-layer strategy gives you an advanced detection capability that is unmatched. For example, an attacker who takes control of a server on your network after a phishing attack can shut down the server's EDR (as well as the antivirus) before running ransomware. If you have an NDR in your network, it can detect and block the attack.

These 2 technologies are therefore complementary. You must make sure you have both in your network.
