Job Application for Software Engineer III | Performance & Sustaining at ExtraHop

ExtraHop is reinventing Network Detection and Response (NDR) to help enterprises and organziations stay ahead of emerging threats with unmatched network visibility, context, and control.

Today’s attackers bypass traditional security defenses through identity-based entry, move invisibly across cloud, on-premise, and data center networks using encryption and trusted applications, and exploit and exit whenever they want. But all of that movement is visible on the network... if you can see it.

By combining the power of NDR with Network Performance Management (NPM), Intrusion Detection Systems (IDS), and forensics in a single, integrated platform, ExtraHop can decrypt and unlock complete packet-level data at wire speed, analyze and correlate it across all your networks, applications, devices, and users with cloud-scale machine learning, and provide a single interface to the SOC to detect, investigate, and remediate modern cyber risks in real time.
