As an N3 aggregator, we’ve made sure our N3 Connectivity offers the ultimate in security. Our robust connections, ensure NHS data and systems stay safe. We also bring a fresh perspective. We work with healthcare clients to look beyond constraints of existing systems, to develop innovative strategies for cloud.

We’ve successfully helped healthcare clients maximise budgets while keeping data and systems secure.  Cloud Route, is OCSL’s own high performance connection to the Public Cloud.  This helps healthcare clients take advantage of Public Cloud, but with the increased security, performance and resilience.  Our robust Enablement Framework helps us dig deep to find the right answers.  It makes sure choices are aligned to clear goals and that legacy applications and services are all optimised for cloud.

The highest Government and N3 status

With N3 (NHS National Network) aggregator status our network connection is considered to be one of the most robust in the UK. Many clients choose OCSL because our security is second to none. We carry the highest accreditations from technology and software leaders.  Our own data centres hold Government OFFICIAL Status and UK Data sovereignty is guaranteed.

Working with OCSL is refreshing…sharp individuals, very attentive and very detail orientated, their subject knowledge is second to none. Unlike other providers, they understood the complexities of hosting medical and patient information
