About
Built by people who ship into Defence and CNI for a living.
SignetAssure is a product of Alton Valley — a UK business that designs, builds and manages mission-critical security, network and application systems for the country’s most demanding environments.
Why SignetAssure exists
We kept seeing the same gap on customer estates: world-class physical security and network infrastructure, undermined by the human side of access — vetting that lived in spreadsheets, evidence in inboxes, badges that outlived clearances.
SignetAssure closes that gap. It’s the layer between the person and the perimeter, designed for the kind of organisation that can’t afford a wrong call.

Founded in 2009 in Derby, Alton Valley delivers across application development, network infrastructure and physical security for UK Defence and CNI — including UK distribution of the CredoID access control platform.

Sovereign by default
UK data, UK hosting, UK people. Sovereignty isn’t a configuration option you have to ask for.
Open to integrate
No black boxes. Clean APIs, signed events, and a willingness to wire into the kit you already run.
Audit is a feature
If you can’t prove what happened, it didn’t happen. We make the proof effortless.
