Sovereignty as a Design Principle

At NoSpamProxy, digital sovereignty is not an optional feature, but a fundamental principle. For small and medium-sized enterprises (SMEs) in particular, it means one thing above all else: maximum freedom of choice combined with complete control over their own security infrastructure. Instead of conforming to predefined platform logic, you retain control over your data, your processes, and your security decisions at all times, transparently, traceably, and independently.

With NoSpamProxy, you decide for yourself how and where your email security is managed. Whether on-premises for the highest control requirements, in the cloud for maximum flexibility, or as a hybrid model for a phased transformation, the architecture adapts to your strategy, not the other way around. The result is a security solution that integrates seamlessly into existing structures while offering the flexibility to confidently meet future requirements.

„Although Microsoft 365 includes its own security features, we route all traffic through our NoSpamProxy as a second, central layer of protection. We rely on the combination of both systems to ensure greater security.”

Marco Riemer, Head of Cloud Services at hagebau IT GmbH

„We work very closely with NoSpamProxy and know that, if the need arises, we can quickly get in touch with someone who will take care of our issue. We also really appreciate the fact that we can communicate with them as equals.”

Michael Drepper, ZIT, Collaboration Software Unit at Essen University Hospital

AI expertise born from real-world application

NoSpamProxy’s artificial intelligence is not just a buzzword or an afterthought.

Instead, it is an integral part of the system architecture, developed from the ground up, trained, and continuously optimized based on real-world email communication within companies.

32Guards is NoSpamProxy’s smart analytics and metadata service, which helps identify threat patterns faster and respond to cyberattacks more effectively. 32Guards processes millions of emails, attachments, and URLs every day. The focus is not on traditional content analysis, but on identifying correlations, patterns, technical characteristics, and relationships that provide clues about trustworthiness or potential threats.

This creates an adaptive security logic that continuously learns and evolves, with full control and transparency.
