Three Decades of Trusted Security Collaboration for Gunnebo Safe Storage and Thornhill Security
Gunnebo Safe Storage is celebrating a 30-year partnership with Thornhill Security, a relationship that continues to support the delivery of complex security projects across Europe.
The two companies have worked together on a significant range of installations across different sectors, including pharmaceuticals and high security sites, often involving specific operational constraints or non-standard layouts. This includes projects within modular buildings, where security solutions need to be carefully planned around space limitations, structural considerations and installation timeframes.
Having an established working relationship has allowed Thornhill Security to involve Gunnebo Safe Storage early in the process, bringing technical input into the design and specification phase. This has helped ensure solutions are developed with a clear understanding of how they will be installed and used in practice, particularly on projects where conditions on site can change.

The partnership has supported delivery of specialist requirements, including the integration of the first Grade 12 vault within a live project environment, as well as a growing demand for vault doors and panic rooms across critical infrastructure. Thornhill is among the first UK customers to supply the Gunnebo Safe Storage Encry lock with OTC software, enabling one-time code access without the need for a network connection.
Work at this level depends on a shared understanding of compliance and performance standards. Such understanding is now being passed in Thornhill Security to the next generation of its locksmiths and safe engineers.
