Surevine is a UK-based technology company that builds secure, scalable collaboration solutions targeted at security-conscious organisations, particularly within government, defence, and law enforcement sectors. The company offers both comprehensive end-to-end solutions and expert consultancy services, allowing clients to engage at a level appropriate to their needs — whether that means adopting a full solution or augmenting existing teams with specialist expertise. Surevine operates within a broader ecosystem of partners and suppliers, ranging from niche specialist service providers to large defence contractors. Its client base includes prominent UK and international public sector bodies such as HM Government, the Ministry of Defence, the Home Office, the House of Commons, NATO, Europol, the UK Cabinet Office, NCSC, DSTL, and the Foreign, Commonwealth & Development Office (FCDO).

Academic institutions such as Imperial College London, Queen's University Belfast, Royal Holloway, and Keio University also feature among its partners. The company's core focus is on enabling secure information sharing and collaboration in environments where data sensitivity and security requirements are high. This positions Surevine primarily in the secure communications and collaboration space, with a strong orientation toward classified or sensitive government and defence use cases. Their consultancy offering extends their capabilities to organisations facing complex security and technology challenges that require tailored expert input.
