Espionage 3.0

Espionage is a unique data security application. It lets you encrypt and password protect individual folders, and interact with them straight from the Finder.
Espionage protects you even if you're forced to give up your password by giving you the ability to have multiple master passwords, each protecting a unique set of folders through a feature called Folder Sets.
Espionage 3 was rewritten and is completely different from Espionage 2, a much more complicated application, still available.
