Executive Profile
Enterprise Solution Architect. Chief Architect. Enterprise Transformation Adviser.
Paul Middleton is an independent Chief Architect and Enterprise Transformation Adviser, trading as Consulting As A Service Ltd, working with CIOs, CTOs, CISOs and transformation leaders across regulated industries, large enterprises and government organisations.
Over two decades, that work has spanned enterprise architecture, digital workplace transformation, identity and security, cloud strategy and architecture governance — most recently as Chief Architect within telecommunications and pensions organisations, and earlier across professional services and public sector delivery.
The common thread is independence: architecture recommendations built on business outcome and risk, not vendor relationship or delivery-team utilisation. That independence is what organisations engage for when a transformation programme has stalled, when governance has broken down, or when a board needs an honest, technically credible second opinion before committing capital.
Alongside enterprise architecture and governance work, Paul maintains a specialist practice in modern authentication and identity strategy — treating identity as critical infrastructure, and designing it with the resilience discipline that implies.
