Z1 SecureMail Gateway - the virtual admin office protects the e-mail traffic of the whole corporation. By centralized encryption and digital signature.It integrates easily into existing e-mail-infrastructures. Because Z1 SecureMail Gateway supports the two internationally-established standards for e-mail security, S/MIME and OpenPGP it is in compliance to every existing e-mail software. In addition, today it already largely conforms with ISIS-MTT and S/MIME v3.Technically spoken the Z1 SecureMail Gateway acts as an SMTP proxy server which automatically encrypts, decrypts and signs e-mails as well as verifies e-mail signatures. It keeps anti-virus, SPAM and content filtering software the necessary access to the e-mail traffic and because of a flexible certificate management it uses user-, domain and group certificates.Z1 SecureMail Gateway: Centralized administrated security for your complete e-mail trafficZ1 SecureMail Gateway acts like an centralized admin office which opens your incoming letters and envelopes outgoing letters.
