How It Works

Deep packet inspection is not a one-time implementation - new applications are continually appearing and evolving. Applications use a variety of domains to deliver an application. For example, Twitter is more than just twitter.com; there are dozens of domains used to deliver images, videos, APIs, and other application assets:

  • t.co
  • twimg.com
  • twitter.com
  • twimg.com.akahost.net
  • twitter.map.fastly.net
  • cs1138.wpc.edgecastcdn.net
  • etc.

Netify DPI uses these domains to identify application network traffic flows. The engine uses hostnames derived from TLS SNI, TLS certificate common names, HTTP headers, DNS requests, DNS hinting, and any hostname that pops out of deep packet inspection.

A domain like cs1138.wpc.edgecastcdn.net may not look related to Twitter, but upon inspection, it is. The Netify analysis and machine learning engines are constantly on the prowl for new domains, network blocks, and behaviors.

The following is a list of some of the protocols that are only available with Signature Updates:
