Sophos SafeGuard LAN Crypt

SafeGuard LAN Crypt provides transparent file encryption for users in large organizations, allowing them to securely exchange data stored locally, on removable media, or network drives. The encryption and decryption processes are handled transparently by a filter driver integrated into the Windows file system.

SafeGuard LAN Crypt works by automatically encrypting files when they are created or saved, and decrypting them transparently when they are read. It uses encryption rules defined by the Security Officer to determine which files are to be protected. These rules are distributed in policy files that are secured via certificates and can be managed centrally.

SafeGuard LAN Crypt offers several benefits, including enhanced data security, secure file sharing, centralized administration, and the ability to integrate with existing PKI infrastructure.

The installation process for SafeGuard LAN Crypt is straightforward and involves installing both the administration and client components. Once installed, you need to configure the encryption rules, define user groups, and manage certificates. This can be done through the SafeGuard LAN Crypt Administration interface, which uses the Microsoft Management Console (MMC).

SafeGuard LAN Crypt provides different security levels for protecting the private keys used for accessing encryption information. You can choose between High, Medium, and Low security levels, with High providing the most robust protection. The security level can be set during the import of a certificate into SafeGuard LAN Crypt.
