What Is Cloud Network Detection and Response (NDR), and Why Is It So Important?<\/h2>\n<\/div>\n<\/div>\n
\n
\n

Cloud network security refers to the strategies, controls, and technologies that protect cloud-based systems and data from threats. Traditional methods often struggle to keep up with the dynamic nature of cloud networks, where workloads, applications, and resources are continually changing. This is where NDR solutions<\/a> make an impact, offering deep visibility into network traffic, detecting unusual patterns, and automating responses across cloud-native environments.\u00a0<\/p>\n

By continuously monitoring network activity, cloud NDR adapts to these unique architectures, identifying risks in real time\u2014even within 75% of traffic that is encrypted. It offers the deep visibility required to spot unusual patterns, mitigate potential risks, and maintain a high level of security across cloud services.<\/p>\n<\/div>\n<\/div>\n
