Well PGP has met VoIP before but meet the latest product to use Phil Zimmerman’s PGP-based Zfone a secure VoIP media encryption software solution also created by Zimmermann. The product to use this technology is Borderware’s SIPassure’s VoIP security gateway.

Interestingly I have written about Borderware before and they seemed to be a very hot company in the IP communications security space who dropped off the radar — out of touch for months. I don’t know what happened to them but they seem to be back with what seems to be a good idea. I am curious to see how it works for them.
