Guide Review - PGP Desktop Home 9.0 - Email Security Program
PGP Desktop Home makes key management particularly comfortable, and it includes some advanced features like split keys that require multiple people for decryption, additional corporate decryption keys and key recovery.
The plug-ins that integrate PGP Mail with several email clients — Outlook 2000/2/3, Outlook Express, Eudora and Lotus Notes — are easy to use, too. Unfortunately, their support for OpenPGP is surprisingly weak, and the free version of PGP Desktop Home does not even offer the plug-ins at all.
In spite of its ease of use and strong (corporate) feature-set, PGP Desktop Home is a bit limited when it comes to securing email, especially if you rely on the free version.
