TrueCrypt
Information security is very important! At work, we like to keep not only passwords secure, but also network documentation, server documentation and any document that has personal or agency specific information. This can be a real pain, and there are very expensive software packages that will create encrypted drives or encrypt virtual volumes. TrueCrypt is a free and open-source encryption package that will create encrypted mounts. It is fast and simple to setup. Encryption is done in real-time and is transparent. It is able to take advantage of AES, Serpent, and Twofish algorithms.
