About Us
Independent assurance for technology governance, compliance, and risk management — delivered by people who have spent decades doing the work.
Technical Assurance Group is built on more than 30 years of hands‑on experience designing, building, managing, and maintaining IT infrastructure across virtually every industry.
We're a team of seasoned IT managers, architects and engineers who have spent decades solving complex technical challenges, modernising legacy environments, and delivering resilient, secure, and scalable systems.
From enterprise networks to cloud platforms, from on‑premise estates to hybrid architectures, we've seen it, built it, and kept it running.
Our mission is simple: provide organisations with the technical assurance, clarity, and expertise they need to operate with confidence.

How we work
We have no vendor affiliations, no reseller agreements, and no commercial incentives that could colour our findings. Our only obligation is to the truth of what we find.
Decades of hands-on delivery mean we assess from the inside out — not from a checklist, but from lived experience of what good looks like.
We translate complex technical findings into clear, actionable language that boards, leadership teams, and delivery functions can all act on.
