Plesk is a control panel and WebOps platform for web hosting: software that hosting providers and businesses use to manage websites, domains, email and servers through a web interface. The vendor describes it as running on all virtualisation and container platforms. It is sold in commercial editions with extension bundles. Because it is installed on the customer's own servers, Plesk is a self-hosted product rather than a cloud service run by the vendor.
WebPros International GmbH, which develops Plesk, has its seat in Schaffhausen, Switzerland. The company is part of the WebPros group. Because Plesk runs on servers the customer provides, the location of the data depends on where the customer installs it. The licence and account arrangements with the vendor are a separate contract. For a European organisation, the choice of hosting environment and the licence terms are the main points to check.
