Network Detection and Response (NDR) is a security measure that monitors network traffic for suspicious activity and responds accordingly. NDR can be used to detect and block malicious traffic, as well as to identify and investigate potential security incidents.

NDR systems are often used in conjunction with other security measures, such as firewalls and intrusion detection/prevention systems. Network Detection and Response systems can be deployed in a variety of ways, including on-premises or in the cloud.

When choosing an NDR solution, it is important to consider the needs of your organization and the specific threats you are trying to protect against. Some common features of NDR solutions include traffic analysis, anomalous activity detection, and security event correlation.
