NSO Group is an Israeli technology company that develops cyber-intelligence tools sold exclusively to government intelligence and law enforcement agencies. The company is best known for Pegasus, described by its own CEO as one of the most sophisticated spyware tools in the world. NSO Group's technology enables government clients to conduct surveillance and digital intelligence operations targeting mobile devices and communications. The company markets its products under a government-only licensing model, requiring customers to obtain export-control authority approval and pass an internal human rights review before being granted access. Stated use cases include counter-terrorism operations, disruption of criminal networks (including trafficking and money laundering), locating missing or kidnapped individuals, and supporting search-and-rescue efforts. NSO Group was established in 2014 through a combination of Israeli and European cyber technology firms. By the end of 2018, the company reported revenues of approximately $250 million. In 2019, Novalpina Capital, a European private equity firm, completed an acquisition of the company alongside NSO's founders and senior management. The company publishes an annual Transparency and Responsibility Report outlining its internal governance, compliance processes, and stated safeguards against product misuse. NSO Group has faced significant controversy and independent scrutiny from researchers, journalists, and governments, with its technology alleged to have been used against journalists, activists, and political figures in multiple documented cases.
