Sovereignty as a Design Principle

At NoSpamProxy, digital sovereignty isn’t just an add-on feature – it’s a fundamental principle. For businesses, this 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 full control over your data, your processes, and your security decisions at all times – transparently, accountably, 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.

NoSpamProxy bietet flexible Deployment-Optionen:

Operated in German data centers
for the highest standards of data protection and digital sovereignty

On-premises for maximum control

Cloud for maximum flexibility

Hybrid for gradual transformation

„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, Division Manager 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 problem. We also really appreciate the fact that we can communicate with them as equals.”

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

„NoSpamProxy provides highly reliable protection for our email communications, is extremely user-friendly, and can be operated efficiently with minimal effort. As a German company, NoSpamProxy also offers us top-notch support and service.”

Dipl.-Ing. Päd. Tobias Walther, CIO, Medical School Hamburg

Practical AI expertise – not just a buzzword

NoSpamProxy’s AI isn’t just an afterthought.

It’s an integral part of the architecture – developed, trained, and continuously refined based on real enterprise email flows.

With 32Guards, NoSpamProxy’s intelligent analysis and metadata system, millions of emails, attachments, and links are evaluated every day. This isn’t about content in the traditional sense, but rather about context, patterns, relationships, and technical characteristics that allow conclusions to be drawn about trustworthiness and threats.

The result is a learning security logic that continuously adapts – without compromising control.

Intelligenter Schutz mit 32Guards

Detection of new attack patterns without the need for signatures

Analysis of metadata rather than content-based approaches

GDPR-compliant processing without access to sensitive content

Collective learning across all NoSpamProxy installations

Full multi-tenant capability

Administrators from different companies or within larger corporate groups each have their own separate, self-contained configuration area in NoSpamProxy. In the message tracking feature, each administrator can only view emails from their own tenant. NoSpamProxy Server ensures that emails are always processed separately by tenant. The multi-tenant capability is of interest to both heterogeneous corporate structures and managed service providers.

Strategic Partnership for Maximum IT Security: Security Awareness Training from SoSafe

The close collaboration between NoSpamProxy and SoSafe, the European market leader in security awareness, is setting new standards in IT security.

For over two years, both companies have been combining their strengths: While NoSpamProxy provides reliable protection against malicious emails, SoSafe raises employee awareness of cyber threats through targeted awareness training.

Instead of an “all-in-one” solution, which often reaches the limits of innovation, NoSpamProxy and SoSafe pursue a specialized approach – for the highest quality, efficiency, and support. The numbers speak for themselves:

  • 99.9% detection rate for spam and malware – NoSpamProxy is a multi-award-winning email security product.
  • 3 million trained employees – SoSafe reduces phishing click-through rates by up to 80% and strengthens the “human firewall.”

The partnership is further deepened through advanced technical integration: In the future, NoSpamProxy’s security checks will be directly integrated into the SoSafe software. This innovation offers companies additional value and strengthens comprehensive protection against cyber threats.
