Detailed Review

NoSpamProxy is built and sold by Net at Work GmbH, an independent, owner-managed company based in Paderborn, Germany, that says it operates with no external investors. The gateway sits between the mail server and the internet, filtering spam, malware and ransomware while also detecting phishing and CEO-fraud attempts. It carries the "IT Security made in Germany" certification and reports more than 6,000 customers.

What separates NoSpamProxy from most of this list is genuine deployment choice: NoSpamProxy Cloud or NoSpamProxy Server (on-premises), not a cloud-only product with an on-prem story bolted on. S/MIME and PGP email encryption with automated certificate management, large-file transfer direct from the email client, and GDPR-compliant disclaimer management are bundled in rather than sold as separate add-ons.

What NoSpamProxy does well

  • Real choice between cloud and on-premises deployment, not cloud-only
  • Independent, owner-managed company (Net at Work) with no external investors to answer to
  • S/MIME and PGP encryption with automated certificate management bundled in, not a paid add-on

Where NoSpamProxy falls short

  • Pricing is quote-only
  • Brand recognition is concentrated in the DACH region rather than internationally
  • Choosing the on-premises option still means owning patching and maintenance yourself

Standout feature. A genuine choice between cloud and on-premises deployment, with S/MIME/PGP encryption bundled in rather than sold separately.
