Top-class email security **Rating:** 5.0/5.0 stars **Reviewed by:** Olaf O. | Geschäftsführer, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** March 13, 2026 **What do you like best about NoSpamProxy?** As a systems house with a focus on cybersecurity, we have the highest standards for our manufacturer partners. Especially in the area of email security, we have relied on NSP for many years and have consistently had very positive experiences with it. We are particularly impressed that NSP consistently focuses on quality and security: The solution is "Made in Germany", BSI-certified, and fully GDPR-compliant. This builds trust – both with us and with our customers. Another major advantage is the flexibility of the platform. NSP can be used both as a cloud and as an on-premises variant, allowing it to be optimally adapted to different customer requirements and IT infrastructures. Overall, NSP convinces us and our customers with high security standards, reliability, and a practical implementation of modern email security. **What do you dislike about NoSpamProxy?** We have not discovered any shortcomings so far that speak against NSP! **What problems is NoSpamProxy solving and how is that benefiting you?** NSP is a problem solver and seeks its equal in the field of email security. NoSpamProxy Protection combines the most advanced technologies to ensure optimal protection against current threats. A special feature to highlight is that NoSpamProxy operates without email quarantine. With NoSpamProxy Encryption, you encrypt emails easily using S/MIME and PGP, while simultaneously guaranteeing GDPR-compliant communication with customers and partners. With NoSpamProxy Large Files, you send files of any size directly from the email client to your communication partners. Simple, secure, and without media disruption. ### 4. Effective spam protection with simple setup **Rating:** 5.0/5.0 stars **Reviewed by:** Lars S. | CTO @ activeIT, Small-Business (50 or fewer emp.) **Reviewed Date:** March 13, 2026 **What do you like best about NoSpamProxy?** I like the way NoSpamProxy works, especially that emails are rejected at the SMTP level when spam is detected. I appreciate the ability to convert Office documents into secure PDFs. The granular configuration options are also impressive, particularly the multi-tenancy feature. The most important thing for us is that NoSpamProxy runs in our own data center. **What do you dislike about NoSpamProxy?** There could be room for improvement by making adjustments to the URL safeguard. For example, the text that is inserted there could be adjusted. But these are minor details, that's complaining at a very high level. **What problems is NoSpamProxy solving and how is that benefiting you?** I primarily use NoSpamProxy to reduce spam emails. It rejects emails at the level when spam is detected and offers the ability to convert Office documents into secure PDFs. ### 5.
