Delivering Outcomes That Matter
We advise, build, protect and run technology for critical services in environments where failure isn't an option.
How we can help you
A clunky process costs people time. Bad data undermines the best technology. We work across people, processes, data and technology together because problems in one area always land on another. Through this work, CDS helps deliver the following outcomes:
Empower and enable people
Whether it's your team drowning in manual work or your customers expecting a better service, we design solutions around people. The result is less friction and better experiences for your employees and customers.
Accelerate modernisation
Legacy systems and fragmented infrastructure don't fix themselves. And waiting carries its own risk. We help you move off them quickly and safely, without disrupting the critical public services that cannot afford to stop.
Drive efficiency and productivity
We identify what's slowing you down such as manual workload, duplicated effort, processes that made sense once but don't anymore, and help you fix it. Your people get their time back and the work gets done faster.
Improve visibility and control of risk
We work with organisations where a security incident isn't just inconvenient, it's a serious failure. We help you modernise without increasing your exposure, with security treated as a design requirement.

Advise
Not sure where to start? Our Discovery, Advisory and Assessment work gives organisations an honest picture of where they are, what's holding them back, and what to do next. You'll leave with best-practice guidance and an actionable plan you can put to work straight away.
Build
We build resilient systems for organisations delivering critical services — public-facing platforms, case management systems, cloud migrations that can't afford downtime, AI applications that need to work reliably at scale. We build to a standard that holds up when it matters.
Protect
Security isn't something you add at the end. It's a decision you make at the start and keep making throughout a service's life. We help organisations build and maintain that posture, across public-facing applications, internal networks, identity and access management, and AI agent security
Run and Optimise
Going live isn't the finish line. For critical public services, it's the start of a long-term commitment to keeping them up and secure. Run and Optimise is CDS's managed service: skilled triage, application-level resolution, proactive monitoring, and 2nd and 3rd line application support.
Start somewhere specific
Not every engagement starts with a big brief. Sometimes getting started at all is the hardest part. Whether you need to fully define the problem, reduce perceived risk, build a business case or test something new, CDS can help you get started quickly, deliver value early and give you the confidence needed to take action and on your next critical initiative. Via a range of fixed-scope engagements, CDS can help accelerate progress:
Application Security Assessment
Understand your security posture, identify gaps and secure your infrastructure.
AI Readiness Assessment
Find out where AI can genuinely help and where it can't, with practical next steps.
Delivery Capability Assessment
An honest view of how your delivery is performing and what to do about it.
Idea-to-Roadmap
Take a problem or an idea and leave with options, a recommendation and a plan of action.
Proof of Concept
Turn a specific idea into a working demonstration, built on your data and infrastructure.
How we work
How we deliver services that can't afford to fail. We build to the Government Service Standard, hold every engagement to a published Engineering Bar, and plan handover from day one, not as an afterthought. Here's how we work.

Customer stories
We work with clients across central government, emergency services, health, financial services and national-scale consumer digital. The common thread is that the services they run can't afford to fail.

Building the UK's digital policing platform
CDS has been the technology partner behind Single Online Home for nearly a decade - the digital front door to policing across England and Wales. The platform serves 41 forces plus British Transport Police, handles 450 million requests a month, and has run at 100% uptime for three years.
Building and sustaining the UK's national emergency coordination platform
Resilience Direct is COBRA's national platform for emergency planning and response, serving 130,000 registered users across every police force, fire brigade, and local authority in the UK. CDS has built and continuously improved it for over a decade, keeping a million-document national repository secure and operational.
