Plesk Panel Email Antivirus

4PSA Clean Server

Email scanning is performed on the same server
The first antivirus for Parallels Plesk Panel to introduce safe, high performance distributed email scanning
On a server overloaded by email scanning processes hosting 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
To avoid resource starvation attacks, emails might pass unscanned at peak times
The server cannot possibly get overloaded with scanning processes therefore emails cannot pass unscanned
Each hosting server uses its own scanning engine, installed on the same server, so resources get spent inefficiently
The fastest and most reliable scanning process that does not affect the hosting services installed on the server
Antivirus updates must be deployed on each hosting server
Antivirus updates must be deployed on scanning nodes only
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 or usage reports for administrators and/or end-users
The highest level of control for end-users; it delivers detailed reports and notifications
No file system scanning for potential threats, no reports sent to administrators
Clean Server also performs file system scanning and sends reports to the admin about the threats detected on the server.
