Top Network Detection and Response Companies

The global NDR market size is projected to grow from USD 3.68 billion in 2025 to USD 5.82 billion by 2030 at a compound annual growth rate (CAGR) of 9.6% during the forecast period. The increasing sophistication of cyber threats, including ransomware, advanced persistent threats (APTs), and supply chain attacks, is driving demand for NDR solutions. With the expansion of hybrid and multi-cloud adoption, network complexity and attack surfaces are increasing. As a result, organizations are investing in advanced network visibility, real-time threat detection, and AI-driven response capabilities to safeguard digital assets, minimize dwell time, and ensure business continuity.

According to MarketsandMarkets, Network Detection and Response (NDR) is a cybersecurity technology that continuously monitors and analyzes network traffic to detect suspicious activities, anomalies, and threats. It leverages behavioral analytics, machine learning, and threat intelligence to identify malicious patterns within east-west and north-south traffic, providing security teams with visibility, forensic insights, and automated or orchestrated response capabilities across physical, virtual, and cloud environments.
