Every day more than 293 billion Emails are sent - more than half of it is spam. Spam not only kills productivity, it is also used to sneak in fraud attempts, spyware, and harmful software. Every day spammers come up with new tricks to circumvent mail filters and the filter programmers try to keep up before they can cause any damage - an endless arms race.

Mit anderen Worten: man kann es sich eigentlich gar nicht mehr leisten, keine Email-Security zu haben. Natürlich, fast alle Email-Services haben irgendwelche integrierten Sicherheits-Features, aber diese erfüllen viel zu oft nur die Minimalstandards.

Genau deswegen bieten wir unseren Mail-Gateway an – ein Extra an professioneller Sicherheit. Im Gegensatz zu den üblichen Filtern befindet sich der Mail-GW vor dem Mailserver und blockiert die unerwünschten Nachrichten, noch bevor sie die Mailbox erreichen. Der Mail-GW gestattet die Filterung für eine oder mehrere Domains auf transparente Weise. Eine Softwareinstallation auf dem Client ist nicht erforderlich.

Institutions and businesses with thousands of users all over the world trust in Mail-GW. So should you.


Mail-GW uses several complementary techniques to recognize spam. With a combination of algorithms, artifical intelligence, and regular updates, Mail-GW can react to the newest spam techniques.


Mail-GW filters incoming emails for viruses, worms, and attachments with questionable content which might contain scripts.

Web interface
