Remove ads
OneAdvanced Group Limited (operating as OneAdvanced) is a British private enterprise software and cloud computing company founded by Vin Murria in 2008. Headquartered in Birmingham in the West Midlands, it supplies business software and outsourced IT services – including hosting and cloud-based systems – to organisations in sectors such as health and social care, education, legal services and the wider public sector in the United Kingdom and overseas. The company has grown through a series of acquisitions and is jointly owned by private equity firms Vista Equity Partners and BC Partners.
Originally listed on the Alternative Investment Market as Advanced Computer Software, the business was taken private by Vista Equity Partners in 2014 and rebranded to OneAdvanced after a strategy refresh in the early 2020s. In 2024 it sold its application modernisation division to IBM for integration into the IBM Consulting portfolio.
OneAdvanced also provides software used in frontline health and care services. In August 2022 a ransomware attack against its health and care systems disrupted NHS 111 and other services and led to the exfiltration of personal data from tens of thousands of people. The incident cost the group tens of millions of pounds in remediation and outage credits and, following an investigation, resulted in a £3.08 million penalty issued by the Information Commissioner's Office in 2025.
