History
The company was founded as SWsoft in 1997 as a privately held server automation and virtualization company. In 2000, the company released the first commercially available operating system-level virtualization container technology. In 2003, SWsoft acquired the makers of Confixx and Plesk web hosting products: Plesk Server Administration (PSA) control panel and Confixx Professional hosting software. Virtuozzo was the core enabling technology behind SWsoft's HSP Complete solution. In 2004, SWsoft acquired Parallels, Inc.

In 2005, the company open-sourced its operating system-level virtualization technology as OpenVZ. In 2007, SWsoft announced that it had changed its name to Parallels and would distribute its products under the Parallels name.

In December 2015, Virtuozzo was spun out from Parallels to become a standalone company. In May 2016, Virtuozzo announced its intention to join the Open Container Initiative.

In July 2021, Virtuozzo acquired OnApp. In October of that year, the company acquired Jelastic.
