False Positive Rate

„Net at Work’s email security solution achieves a detection rate of more than 99.96% for the spam corpus as well as for the subcategories malware and phishing. As there were no false positives, the product was awarded VBSpam+ certification.“

Ionuţ Răileanu and Adrian Luca, Virus Bulletin, VBSpam Email Security Comparative Review September 2024

You need protection against spam & malware? Avoid the quarantine trap.

False positives are a big risk when using a conventional anti-spam solution. If these misclassified emails are deleted or quarantined, they can either not be detected and restored at all or only with considerable difficulty.

Why is an email quarantine dangerous?

The BGH ruled that emails that are made available for retrieval on the recipient’s mail server during normal business hours are generally considered delivered to the recipient at that time. Of course, this also includes spam and quarantine folders.

Block spam emails. With the effective spam protection of NoSpamProxy.

New with 32Guards.

NoSpamProxy Protection checks each email and classifies it using various anti-spam filters. The new AI-based 32Guards also evaluates the metadata of attachments and URLs. If an email is classified as spam or potentially dangerous, the system does not accept this email. Only messages classified as trustworthy can reach the inbox.

NoSpamProxy is one of the few products on the market that guarantees full compliance with the demanding German law (in particular according to $206 StGB, §88 Telecommunications Act). NoSpamProxy offers effective protection against spam and malware.

„Currently, with the help of 32Guards, we evaluate around 45 million emails with 15 million attachments and 400 million links from German-speaking countries every week. This enormous database enables us to recognise developments and trends at an early stage and to react to them. In this way, we are able to stop the usual cyber criminals in their tracks.“

Sarah Lahme, Teamleitung 32Guards

Over 6,000 companies entrust the security of their Email communication to NoSpamProxy.

What makes NoSpamProxy Protection so powerful?

Sender- und Empfängerreputation

Sender and recipient reputation

With the automated sender identification, NoSpamProxy can clearly determine whether an email actually originates from the specified sender. NoSpamProxy uses the sender reputation methods, i.e. SPF, DKIM, DMARC, DANE and ARC. To protect specifically against phishing and CEO fraud attacks, an extensive check of the header FROM is also carried out. This prevents attackers from pretending to be your CEO or colleague in emails.

„Although Microsoft 365 comes with its own security solutions, we route all traffic via our NoSpamProxy as a second, central protection mechanism. We rely on the combination of both systems for greater security.”

Marco Riemer, Head of Cloud Services at hagebau IT GmbH

WWK Logo

„With NoSpamProxy and GlobalSign, we were able to easily implement the requirements of the EU GDPR for data protection-compliant email communication. The combination of the two products reduced the roll-out and ongoing administration effort to a minimum.”

Marcus Bethmann, IT System Administrator Groupware & Identity Services at WWK Insurance Group

„We work very closely with NoSpamProxy and know that, if the worst comes to the worst, we will quickly have someone on the line to deal with our problem. We also very much appreciate the exchange at eye level.”

Michael Drepper, ZIT, Collaboration Software Unit at the University Medical Center Essen
