‘We believe Quest is well-positioned to capitalize on emerging growth trends in identity-centric cybersecurity, data intelligence and IT operations management software,’ say Clearlake’s Prashant Mehrotra and Paul Huber. Clearlake Capital has agreed to purchase Quest Software for a reported $5.4 billion including debt after a half-decade of being owned by Francisco Partners. The Aliso Viejo, Calif.-based cybersecurity, data intelligence and IT operations management software provider will continue to be led by Patrick Nichols, who has served as CEO since April 2020. Terms of the transaction weren’t disclosed, although The Wall Street Journal reported the $5.4 billion purchase price Sunday.
