SecurE-mail Gateway

The SecurE-Mail Gateway is the efficient and cost-saving central manager of your secure E-Mail communication

The SecurE-Mail Gateway centralizes the following functions:

  • Standard administration for secure E-Mails
  • E-Mail encryption/decryption/signature according to the S/MIME and OpenPGP Standard
  • E-Mail encryption with Utimaco SafeGuard® PrivateCrypto
  • Automatic generation of keys and certificates
  • Automatic import of certificates
  • User and domain certificates (corporate certificates)
  • Configuration via the web management

E-Mail exchange is the most commonly used internet application. The information exchange by electronic post alone does not reflect the corporate-specific organizational structures. If specific procedures with far-reaching consequences should be handled this way, it will be necessary to use encrypted and/or signed E-Mails, which is, among other things, the case of the stand-in arrangements, the distributed processing of documents or the issuing of receipts of delivery. Cryptographic operations, particularly when bound to single persons or workplaces, may, however, obstruct the workflow. Cryptographic operations for secure e-mail are the E-Mail signature and the E-Mail encryption.

E-Mail-Signature

One important issue in the modern usage of e-mails is their authenticity. Even if most users still make a difference between e-mails and written documents, they still have great confidence in e-mail communication for their daily business transactions. Thus, serious loss may occur as a result of falsified, user-misleading e-mails. Classic e-mail services do not provide a secure solution for the verification of the e-mail origin. Moreover, they only provide cryptic information which can only be understood by experienced system administrators. Digital signature provides a secure and user-friendly solution to verify the origin (sender's signature) or the route of transport (route confirmation).

E-Mail-Encryption

In addition to authenticity, confidentiality also is an essential aspect of modern e-mail communication. The comfort of modern e-mail services makes it invisible for the user whether e-mail continues to stay within the secured area of his company or is led through insecure public networks. In the modern working environment, including teleworking and outsourcing, these frontiers are becoming blurred. The encryption of e-mails is an important mechanism enabling companies to take advantage of the e-mail facilities without taking security risks.

SecurE-Mail Gateway: Mode of operation and concept

This is the starting point of the SecurEmail Gateway concept. The SecurEmail Gateway is integrated and located centrally in the network and enables the application of a central corporate directive for the distribution of e-mails, as well as the application of cryptographic operations.


According to the basic approach of the Gateway, The SecurE-Mail Gateway is always located in the central area of the network (Common Point of Trust). The SecurE-Mail Gateway solution decrypts and verifies incoming E-Mail and encrypts and signs the outgoing emails. Due to its function as a “central post office”, the Gateway ensures confidentiality (encryption) and integrity (signature) for the complete E-Mail communication. The SecurE-Mail Gateway represents the upgrading of the E-Mail server already used. Defined user groups or even single users are able to get their E-Mails signed automatically before forwarding them.

The procedures of encryption/decryption, signature and verification are being handled in a user-transparent way. If the recipient’s certificate is available, the E-Mail to be sent is encrypted automatically. The centralized storage of received certificates makes the encryption possible even if the sender of the E-Mail has not activated any direct communication with the e-mail recipient yet.
