Plesk™ is a complete hosting automation solution specifically designed to allow quick deployment and simplified management of a Linux based server. It delivers the stability demanded by Hosting Service Professionals while providing the self administration interfaces and end user access for mail, domain, reseller and server level administration.

Plesk auto-installs in minutes and lets non-technical personnel perform a wide variety of administrative tasks — from creating new e-mail accounts to managing entire domains — all with point-and-click simplicity.

The perfect solution for both dedicated server and shared domain management, Plesk deploys and configures all of the systems you need to run a webserver. Tiered login levels provided encrypted and secure access to for system administrators and domain resellers as well as their clients and domain owners. Plesk effectively lowers the threshold for non IT personnel to use, create and manage a Linux based system.

Plesk provides four tiers of administration: admin, client, domain, and mail name user. All can perform various tasks at remote locations via any standard Internet browser.

Plesk users do not need to possess the advanced knowledge of the operating system in order to use Plesk.

As soon as Plesk is installed, both administrators and clients are ready to manage the system. Plesk provides great flexibility to the user, enabling him/her to remotely access and administer servers at anytime. The default settings provided for opening accounts and domains can be changed with the click of a button. With Plesk, each client can create his/her own settings and make his/her own adjustments.

Plesk uses extensive security measures to assure your system of the highest possible integrity and protection. It should be noted however that this is limited to Plesk and the software it installs. The security of the server operating system is considered the responsibility of the system administrator and is not part of the Plesk installation and/or setup.

Plesk uses the secure HTTP (HTTPS) protocol. All documents and communications between users and the server are fully encrypted and secure.

Plesk provides a free self-signed secure socket layer (SSL) certificate that enables secure transactions between a remote user and Plesk. However, this certificate is not from an "official" authority and will not be recognized by the web browser as being valid for the login URL, which results in warning messages. If you wish to use an authentic SSL certificate for the Control Panel you can. Certificates can be purchased directly through the Plesk control panel or by contacting a certificate-signing authority directly.

When creating physical hosting with PHP support, you are unable to start an external program from the PHP script. It is impossible to read or write files above the user's home directory.

There is a possibility of entering different IP-addresses for A domain record and domain hosting address (which is added into web server configuration file) to ensure that the server functions properly behind the firewall.

Plesk provides additional security measures, allowing the administrator to restrict access to control panel from specific IP addresses.
