Email encryption gateway

CipherMail email encryption gateway supports four encryption standards: S/MIME, OpenPGP, TLS and PDF encrypted email. S/MIME and OpenPGP provide authentication, message integrity and non-repudiation and protection against message interception. S/MIME and OpenPGP use public key encryption (PKI) for encryption and signing. PDF encryption can be used as a lightweight alternative to S/MIME and OpenPGP. PDF allows you to decrypt and read encrypted PDF documents. PDF documents can even contain attachments embedded within the encrypted PDF. The password for the PDF can be manually set per recipient or a password can be randomly generated. The generated password can then be automatically delivered to the recipient via an SMS Text message or, the password can be sent back to the sender of the message.

The CipherMail gateway comes in three different versions: the free open source community edition, the Small and medium-sized enterprises (SME) edition and the Enterprise edition. For differences between these versions, see the feature comparison tables below.
