As new and more sophisticated cyber-attacks evolve, mobile devices have become a popular threat vector. Tresys XD Air™ provides unique mobile media protection by ONLY allowing known good content to be shared. Using a kiosk-based solution, XD Air inspects, filters and cleans data on your device, making it safe to use, even in the most sensitive networks. XD Air was developed under the USG program name of FiST in response to the highly publicized USB "thumb drive" threat in November 2008. As a result, USB devices have been restricted or even banned in critical environments. However, these drives were widely used to share vital information between users, partners and applications so the need for a solution was evident. This has been achieved by enabling the implementation to scan based on "known good" content only. Unlike virus scanners that rely solely on looking for virus signatures, XD Air's deep content inspection relies on evaluating each file type on references of known good content thereby ensuring zero-day exploits are stopped.
