Domain encryption

Domain encryption provides a standard S/MIME public key for the entire email domain for a SEPPmail Secure Email Gateway. If desired, the S/MIME key can also be “trusted” by an official CA. This can be used to encrypt messages for any recipient (email address) in the corresponding company. Unlike domain signatures, which are not recommended, domain encryption is a reliable tool for protecting the content of e-mails against unauthorized access. If two e-mail gateways communicate with each other, the entire e-mail traffic between the two companies can be completely protected by simply exchanging the two public domain keys.

This process can be completely automated thanks to the free SEPPmail Managed Domain Service. The service also ensures that all connected SEPPmail Secure Email Gateways know the public key for the other connected SEPPmail Secure Email Gateways. So, all email traffic from one gateway to the next can be encrypted automatically and transparently. Currently, more than 10’000 email domains are registered and therefore our customers are able to secure the entire mail traffic bidirectionally out-of-the-box with the same number of domains.
