D2NA provide comprehensive Cyber Security Assurance and Operations services.

Using our CyberAscend framework, we integrate the best Cyber Security practices from the NCSC into our services which ensures that our customers can confidently deploy, manage, and maintain their business-critical IT services securely.

D2NA was established to help organisations use technology securely, responsibly and with confidence. Over time, the business has evolved in line with the changing threat landscape and increasing regulatory demands faced by organisations.

Today, D2NA builds on more than two decades of experience across IT services and cyber security, combining deep technical capability with a strong governance and assurance mindset.

The organisation has deliberately transitioned from a traditional IT services model into a security‑led partner, focused on advisory, assurance and operational security services aligned to the Microsoft ecosystem.

This evolution reflects both a change in ownership and leadership focus, and a clear commitment to supporting organisations as they scale, modernise and operate securely in increasingly complex environments.

D2NA is led by an experienced leadership team with deep exposure to enterprise and regulated environments. As a result, clients benefit from a partner that combines hands‑on technical leadership with a mature, enterprise‑grade approach to decision‑making, delivery and long‑term service evolution.
