it has been chosen by
thousands of service providers and businesses. They
all rely on Spam Guardian to keep spam messages away from email.
Add Clean Server antivirus for a total email protection!
Compatible with Plesk 8, Plesk 9 and Plesk 10 for Linux.
Spam Guardian provides the most efficient filtering process even if it is installed on an infrastructure with a single server.
Administrators, resellers, and customers have access to detailed statistics regarding the spam-filtering process, allowing them to understand the email traffic and the process efficiency.
The software is able to learn automatically, based on the profile of the spam emails it receives. Also, due to the network tests, threats are detected before they can be analyzed on the local deployment.
The distributed filtering architecture can address any peak in email traffic. Regular hosting server services or email services are not affected by the filtering process.
Spam Guardian offers the best deal from a business and technical perspective. Due to its technology and licensing methodology, the setup and operation costs are much lower than with other solutions.
Spam Guardian comes with 4PSA's extended experience in providing technical support services. In our customers' own words: "Wow!! Now that's what I call service."
