Twelve UK universities including Oxford, LSE, and Imperial College paid a private security firm run by former military intelligence officials at least £440,000 since 2022 to monitor student activists and academics via social media scraping and background checks, with particular focus on pro-Palestine protesters. The firm, Horus Security, compiled intelligence reports on student protest groups and conducted assessments on Palestinian guest speakers and pro-Gaza PhD students without public disclosure. Most universities either denied the characterization as surveillance or claimed the monitoring was for 'security risk identification' from public sources, though the University of Sheffield and Imperial both downplayed the scope of monitoring. The UN special rapporteur on assembly and association flagged 'profound legal concerns' about AI-powered data harvesting on students by private, unaccountable firms—a practice that reveals the infrastructure of campus protest monitoring now operating beneath institutional transparency.
