Domains
Identifying the applications on your network starts with their domains. Netflix, for instance, utilizes over 20 distinct domains to deliver a single stream. They aren't alone - most modern services rely on a complex web of hostnames that are notoriously difficult to map.
We've done the heavy lifting for you. Our engine tracks over 2,500 applications, with signatures refreshed 2–3 times a week to keep pace with the ever-evolving web.
