PGP Desktop Professional operates as a local desktop mail proxy service, automatically encrypting/decrypting messages according to policy. PGP Desktop Professional supports the two global email encryption standards, OpenPGP and S/MIME, automatically discovering keys and certificates. The PGP Whole Disk Encryption engine operates at a system level between the operating system and the disk drive, providing user-transparent, sector-by-sector disk encryption and decryption. A successful pre-boot authentication unlocks the decryption key, enabling users to work without any additional changes to their experience. When centrally managed, PGP Desktop Professional key management, policy, and software updates are managed by PGP Universal Server.
