Detect dangerous attachments early

The 32Guards DeepFile Analyzer scans files in a fraction of a second and reliably detects suspicious content such as scripts, malicious URLs, or malware—before it is delivered.

Faster analysis than traditional sandboxes

Thanks to static file analysis, there is no need for time-consuming dynamic file execution. This allows attacks to be detected more quickly and makes it significantly harder for attackers to bypass sandboxes.

Recall Emails That
Have Already Been Delivered

With 32Guards Recall, you can remove emails from inboxes even after they’ve been delivered if new information indicates a threat, automatically and with centralized control.

Seamless integration into existing processes

Protection ATP integrates directly into the existing NoSpamProxy attachment management system and complements your existing security policies without requiring any additional administrative effort.

NoSpamProxy Protection ATP – Advanced Threat Protection
for secure email communication

Cyberattacks via email are constantly evolving. Modern malware, compromised senders, and threats detected too late pose ever-greater challenges for businesses. With NoSpamProxy Protection ATP, you can specifically enhance your existing email security with additional protection mechanisms against advanced attacks.

The new Advanced Threat Protection module combines ultra-fast static file analysis with intelligent recall functions for messages that have already been delivered. This allows you to identify risks earlier, respond more quickly to new threats, and reduce security incidents in the long term, without adding complexity for administrators or users.

32Guards Recall: Defusing Threatening Emails After Delivery

Not every threat is detected immediately. This is exactly where 32Guards Recall comes in: Emails that have already been delivered can be identified retroactively and automatically removed from inboxes.

Administrators receive automatic alerts, including relevant Indicators of Compromise (IOCs), as needed. The message tracking feature allows administrators to determine which recipients are affected.

Two ways to defuse emails that have already been delivered

„Today, many threats no longer arise simply when an email is received, but evolve dynamically. With NoSpamProxy Protection ATP, we create additional layers of security to both block dangerous attachments early on and recall messages that have already been delivered in a controlled manner.“

„After a short break-in phase at the beginning, we quickly had peace of mind and NoSpamProxy has been doing what it is supposed to do ever since: reliably protect us from cyber threats and spam in the background. This is our idea of perfect mail security.”

Keven Kanet, Head of IT Infrastructure, OLYMP Bezner KG

„Although Microsoft 365 comes with its own security solutions, we route all traffic via our NoSpamProxy as a second, central protection mechanism. We rely on the combination of both systems for greater security.”

Marco Riemer, Head of Cloud Services at hagebau IT GmbH

„We work very closely with NoSpamProxy and know that, if the worst comes to the worst, we will quickly have someone on the line to deal with our problem. We also very much appreciate the exchange at eye level.”
