Extrahop

Extrahop is a network detection and response (NDR) platform designed to provide real-time visibility, threat detection, and investigation across hybrid and multi-cloud environments. It passively analyzes network traffic at scale, reconstructing transactions and decrypting supported protocols to surface suspicious behavior, performance issues, and security risks. Its primary purpose is to help security and IT teams rapidly detect, validate, and respond to advanced threats that traditional endpoint and perimeter tools may miss.

Extrahop continuously inspects east-west and north-south traffic, using machine learning and behavioral analytics to identify anomalies such as lateral movement, command-and-control activity, data exfiltration, and misuse of credentials. It offers full packet capture, session reconstruction, and rich metadata, enabling deep forensic analysis without deploying agents. The platform integrates with SIEM, SOAR, EDR, and cloud services, allowing automated response actions such as quarantining devices, blocking connections, or enriching alerts. Dashboards, visualizations, and guided investigations help teams quickly pivot from high-level alerts to specific devices, users, and transactions.
