Data safe haven

A secure data-handling environment that allows controlled, audited access to sensitive datasets for approved research, applying technical, physical, and procedural safeguards; effectively a synonym for trusted research environment (TRE) in much current usage, though the term has older roots in NHS information governance.

Editorial commentary

The 'data safe haven' terminology was used in NHS England and Scottish government information-governance literature from the late 2000s onwards, predating the dominance of 'TRE'. In practice the two terms now overlap completely. Examples include the eDRIS Safe Haven in Scotland and the SAIL Databank in Wales — both of which describe themselves as safe havens and operate under the Five Safes framework.
