UK told its Big Tech habit is now a national security risk

A report by the Open Rights Group warns that the UK's deep reliance on US Big Tech companies across public sector infrastructure has become a national security risk. The report, titled 'Tech Giants and Giant Slayers,' argues that a small group of American megacorps have entrenched themselves in critical systems, shaped policy in their favour, and created economic waste — with the Competition and Markets Authority estimating at least £500 million per year overspent on cloud services. Legal frameworks like the US CLOUD Act further expose UK data to foreign jurisdiction. The report calls for greater use of open source software, domestic tech capability, and a formal digital sovereignty strategy to reduce dependency.
