Case Study: Viasat achieves faster detection and network-wide threat visibility with ExtraHop

Reduce Time to Detect At Scale with Network Detection and Response Tools

Viasat, an ISP serving military, government, enterprises, small businesses, and home users, needed to detect and stop diverse, industry-specific attacks despite having no authority over endpoints — only the traffic passing through their network. That limitation risked leaving customers blind to threats unless Viasat could achieve deep visibility and behavioral understanding across many customer types and attack tactics.

By deploying ExtraHop RevealX for network detection and response, Viasat added behavioral modeling, network context, and threat-intel enrichment to spot scanning, open‑port discovery, brute force attempts, successful logins, and ransomware payloads. The solution enabled Viasat to stop ransomware attacks customers didn’t even know were happening, gain a clearer risk assessment for each connection or IP, and more confidently analyze, mitigate, and respond to potential threats.
