Wessex Secure Data Environment - Home Part of the NHS Research Secure Data Environment Network NHS

Welcome to the Wessex Secure Data Environment

The Wessex Secure Data Environment (or SDE) is unlocking the potential of your NHS data to support research, create life-saving new treatments and medicines, and bring wider benefits to patients and our NHS. 

How should we run the SDE? Our Improving Tomorrow’s Health campaign is asking people in Wessex to tell us how the SDE should be run to ensure it meets our local needs and aspirations. 

The Wessex Secure Data Environment is a secure, NHS-owned platform.

But this isn’t just about technology - it’s about people. Across Wessex, patients and the public are sharing their hopes, concerns, and expectations for how this platform should be run. Their voices are shaping the future of NHS data use. I invite you to join the conversation and help us make sure the Wessex SDE works for everyone. Your voice matters!"

Our vision and mission

Our vision is to unlock the power of NHS data to support research, create life-saving new treatments and medicines, and bring wider benefits to patients and our NHS.

Our mission is to provide an online platform where large amounts of NHS patient data is stored, linked together, and accessed by researchers.

This platform is the Wessex Secure Data Environment. It has been built to the highest privacy and security standards for NHS data.
