About Sentinel

IT Infrastructure You Can Trust, Built for Gloucestershire Business

Sentinel Infrastructure was founded with a straightforward purpose: to give small and medium-sized businesses across Gloucestershire and the South West access to professional, responsive IT support that used to be the preserve of large corporates.

Our Story

Different by design. Local by choice.

Sentinel Infrastructure was built on the frustration of seeing local businesses underserved by IT providers that were either too large to care or too small to cope. We set out to create something different: a local IT partner with enterprise-level expertise and the responsiveness of a team that genuinely wants to see your business succeed.
