Our Journey
I3S Advisory is delivering secure IT infrastructure and advanced surveillance solutions. The name I3S stands for Intelligent Infrastructure, Innovation & Integrated Solutions a reflection of our mission to design systems that are resilient, future-proof and built around client needs. We help organisations navigate the complexity of digital transformation with confidence, acting as a trusted partner from early strategy through to live operations.
Our vendor-agnostic approach ensures that clients are not tied to single technologies or suppliers, but instead benefit from pragmatic, best-fit solutions. We work across transport, healthcare, and critical infrastructure environments where resilience, compliance, and measurable outcomes are essential. With a focus on governance, risk reduction and operational visibility, we advise on cloud-first strategies, integrated systems and IT leadership.
By applying recognised frameworks such as TOGAF, ITIL and GDPR standards where relevant, we ensure every project not only delivers technical outcomes but also supports long-term business transformation. We also help organisations evaluate and adopt emerging technologies from AI-driven analytics to automation ensuring they are introduced securely, compliantly and with measurable outcomes.
