Is GnuPG/OpenPGP a good solution to protect internal company email communication?
With PRISM and previous major company hacking news stories, I'm looking for a solid way to protect company confidential information while communicating by email?
Another concern is that most people are often need to access their email while on the move. It seems that Android does not yet have any solid support for GPG/PGP encryption through official apps.
Is GnuPG/OpenPGP more of a hassle than a benefit in a corporate environment?
