Opening menus, paying parking fees, gaining entry to events, calling up information or logging into a WLAN, all this is possible with the help of QR codes. QR codes are practical, but can also be misused for criminal purposes: So-called “quishing” is now a widespread method used by fraudsters to obtain sensitive information such as usernames, passwords and credit card details. We explain how quishing works and how you can protect yourself in our blog post.
The latest update extends the functionality of the Outlook Add-in to include encryption and signature functions, among other things. This means that shared stack customers can now also use features that were previously reserved for NoSpamProxy Server and Enterprise Stack customers.

It is essential for companies to continuously update and improve their IT systems. We meet this need with a sophisticated update system for the two products NoSpamProxy Server and NoSpamProxy Cloud. Through regular updates, we ensure that NoSpamProxy users always benefit from the latest features and optimum security.
Cloud services are now an important part of the working world, and as digitalisation progresses, more and more processes are being shifted to cloud services. But what if spammers also take a liking to these easy-to-use services and use them for phishing attacks?
For the seventh time in a row, NoSpamProxy has scored impressively in the survey conducted by analyst firm techconsult, which is based on real user feedback. The above-average product loyalty and recommendation rate reflect the strong focus on customer satisfaction.
