I have been using TrueCrypt volume encryption since a long time. It is a nice product, no doubt. But when I see it's commercial counterparts like PGP and WinMagic, I wonder how reliable the open source products are. Does any government organization use these products? When you are serious about encryption, you will think of commercial products as they are tested thoroughly, have been designed by experts in the field and most importantly, many government organizations are relying on them.
I want to know, when seriously talking about mission-critical data and encryption, should one go for open source tools?
