It's the Best

Spam Guardian features the 4PSA Cloud technology that makes it the most advanced spam filtering solution ever designed for Plesk Panel servers.

Traditional Plesk Panel Anti-Spam	Spam Guardian
Email filtering is performed on the same server	The first anti-spam solution for Parallels Plesk Panel to introduce high performance, distributed email filtering
On a server overloaded by email filtering processes important services like http or database lack resources	Designed to scale with the infrastructure; the only solution available that scales from one hosting server to thousands
Emails might pass unfiltered at peak times to avoid resource starvation attacks	There is no way to overload the server with filtering processes; emails cannot pass unscanned
Each hosting server uses its own filtering engine, installed at the same server, so resources are inefficiently spent	It is the fastest and most reliable filtering process that does not affect hosting services installed on the server
The spam learning database is located at server level and its knowledge base is limited	As filtering is distributed in a specialized infrastructure, the learning database contains more data
High memory footprint and CPU consumption, difficult to install on virtual machines	The lowest memory footprint, the most efficient engine for virtual machines
No statistics and usage reports for administration or end-users	The highest level of control for end-users; it delivers detailed reports and alerts
