NoSpamProxy: The Right Choice for Enterprise Environments

25Reports, 32Guards, All Topics, NoSpamProxy Cloud, NoSpamProxy Disclaimer, NoSpamProxy Encryption, NospamProxy Large Files, NoSpamProxy Protection, Product

CEO fraud, phishing, ransomware via infected attachments: Email remains the preferred entry point for attackers. In enterprise environments, the risk is magnified: more mailboxes, more locations, more entry points. And the attacks are becoming more sophisticated. AI-generated text, spoofed sender domains, context-specific attempts at deception – what used to be recognizable by poor spelling is now almost indistinguishable from a genuine sender. Enterprise organizations with hundreds or thousands of mailboxes, complex IT landscapes, and strict compliance requirements have unique needs. This is where NoSpamProxy comes in.

Server und Cloud Unterschiede und Wechsel Tipps 800x800

NoSpamProxy Server and NoSpamProxy Cloud: Differences and Tips for Switching

All Topics, NoSpamProxy Cloud, NoSpamProxy Disclaimer, NoSpamProxy Encryption, NospamProxy Large Files, Product

NoSpamProxy Server has proven itself over the years as a reliable on-premises solution for email security. Many companies have been using the solution for a long time—and for good reason: control over their own infrastructure, the ability to customize configurations, and independence from external services are compelling arguments for on-premises operation. But the IT landscape is changing—and cloud solutions are increasingly coming to the forefront. NoSpamProxy Cloud offers a compelling alternative to on-premises operation with NoSpamProxy Server. Both versions are developed on a shared codebase. Those who switch will find a familiar environment on the other side. In this article, we highlight the key differences between NoSpamProxy Server and NoSpamProxy Cloud—and explain how to successfully transition to the cloud step by step.

NoSpamProxy enables DKIM signing of automated emails – update now!

25Reports, All Topics, News, NoSpamProxy Cloud, Product, Tech & Support, Updates

DMARC reports are a key tool for checking whether a domain’s SPF, DKIM, and DMARC configuration is effective and whether all legitimate senders are being authenticated correctly. Deviations – especially inconsistencies or a lack of alignment between SPF and DKIM – indicate problems in the email infrastructure. A practical example shows why a detailed DMARC analysis is essential for detecting and permanently resolving such problems.

Wie Cloaking Phishing-Angriffe tarnt 800x800

How cloaking disguises phishing attacks

32Guards, All Topics, NoSpamProxy Cloud, NoSpamProxy Protection, Product

Traditional email security solutions check URLs when a message is received. If the linked page appears normal, the email is allowed to reach the inbox. But what if security systems see something different than the users who later click on the link? Cloaking techniques make this possible—and thus call into question a fundamental principle of URL filtering.
