Extend your DPI Library with Qosmos Signatures

The Challenge

Product vendors with in-house DPI libraries face the costly challenge of constantly updating signatures for protocols which change regularly and without prior notice. Some basic protocols are easy to manage since they are relatively stable (IMAP, SMTP, POP HTTP); however, a growing number of protocols are proprietary and evolve at a rapid pace, for example web sites, social networking, video streaming and gaming applications. Updating signatures for these protocols requires internal resources for development, testing and validation, which can slow down product cycles and detract from the development of your core technology.


The Solution: Complement your own Signatures with Qosmos

 Qosmos Signatures

By complementing your own signatures with Qosmos signatures, your developers can focus on their core product while Qosmos keeps up with the constantly evolving applications and protocols.
