Netify DPI - Application Detection
The millions of data flows streaming across the network each month share one thing in common: they belong to an application.
Today's applications come in many forms - from desktop programs to mobile-specific apps to cloud-based services like Dropbox, Netflix, and Google Docs. Having the ability to identify specific applications running on the network in real-time is a significant challenge due to the increasing use of encrypted communications.
Knowing very little about the applications streaming across the network and the Internet isn't an option. While technologies like NetFlow are good at tracking total packets, NetFlow and others cannot inspect the entire packet (Deep Packet Inspection) to access metadata that will help you accurately classify an application. At the other extreme of application detection are technologies that introduce "man-in-the-middle" solutions on internal networks to identify applications. The downsides of this approach are numerous:
- Increases complexity with deployments
- Weakens security posture
- Compromises privacy
- Introduces additional attack vectors
- Decreases performance
Netify brings you the best of both worlds - accurate application detection without the invasive techniques employed by solutions that implement packet decryption/re-encryption.
How Does Netify Monitor Apps on The Network?
Identifying unencrypted traffic on your network is the easy part. Where things get interesting - and where many solutions fail - is with the use of encrypted protocols. Netify's deep packet inspection has an advantage over non-DPI technologies like NetFlow by being able to inspect and extract application detection metadata from encrypted communications.
With extensive DPI signature updates, Netify has a tremendous advantage over competing solutions in its ability to apply machine learning and other techniques to continually update its application database. Updates from Netify's labs are pushed to Netify DPI agents for continuous quality improvements.
