Our Value Proposition

DTAC is a minimum and living safety standard for the NHS market. For a company to be able to sell its products to the NHS it needs to get DTAC compliant first.

The earlier you start working towards compliance the better. Neglecting this domain leads to what we call compliance debt, which is costly to remedy later on.

We help healthtech be a better and safer space by ensuring healthtech products are deployed and used in a safe way.

We demystify, unpick, and simplify compliance for healthtech companies. We help you achieve and maintain compliance across all DTAC domains:

  • Clinical safety
  • Data protection
  • Cyber Security
  • Interoperability
  • Usability and accessibility

To us, DTAC is not just a tick box - we help startups get compliant and stay compliant by installing a culture of compliance.

Our expertise in interoperability, clinical safety, cyber security and data protection allows us to offer a unique integrated compliance service.

We are much more than a compliance partner. We can get involved in product development aspects and provide valuable advice and feedback on how to incorporate compliance requirements early on.
