NoSpamProxy is an e-mail security gateway developed by Net at Work GmbH in Paderborn. It covers spam and malware filtering, e-mail encryption with S/MIME and PGP, secure transfer of large files and e-mail disclaimers. The product comes in two forms: NoSpamProxy Cloud, which the vendor operates, and NoSpamProxy Server, which runs on the customer's own infrastructure.
Net at Work GmbH describes itself as an independent, owner-managed medium-sized company that grows organically and operates without investors; no parent company is named on its website. For the cloud version, the vendor states that data is processed in certified data centres within Europe. The on-premises server keeps mail processing inside the customer's own infrastructure. The product carries the TeleTrust 'IT Security made in Germany' seal, and the vendor states that it helps organisations protect personal data under the GDPR. For a European organisation, the combination of a German supplier, EU-based cloud processing and a self-hosted option is the main point.
