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 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.
