The SecuMail Filter Technology

The filter system for an excellent filter rate and optimal protection against fraud attempts and malware

Analysis of dangers and threats in e-mails

All incoming emails and their attachments are broken down into their component parts. This includes the extraction of messages and file attachments, as well as the unpacking of archives to check all potentially dangerous content.

Part of the SecuMail security check is the detection of viruses, executable files, unwanted attachments, scripting languages and macros in documents. In addition, the examination of links to fraudulent websites. This comprehensive process ensures the security of your communications and protects you from potential threats.

Minimize human error, make spam filters more precise

Our goal in the area of spam filtering is to protect against human misjudgements (e.g. through social engineering) and at the same time to keep the number of incorrectly filtered emails low. We achieve this by using several thousand tests that evaluate various characteristics and assign corresponding points. The sum of these points forms the spam score, which ultimately decides whether the email is held as spam or delivered to the recipient.

Filter in the cloud

Our cloud-based service gives you the advantage that you don’t have to install or manage any software. The SecuMail team continuously adjusts the software. Thanks to our full service, they are protected from daily threats without having to take action themselves. Our systems work at several locations in Germany.

SecuMail is integrated into your company infrastructure via the MX record. After successful conversion, the SecuMail servers check the mails and either quarantine them or deliver them directly to your mail server.

That was a WOW effect for us. We had prepared ourselves for training, but no one needed our help. […] I don’t know of any other product that works comparatively effectively.” “ H. Siegert IT-Sicherheit – Elektro Kreutzpointner IT-Systeme
