Edge and Application Security
Resilient, secure access to your digital services, from the edge to your application.
What this service is
Security isn't a layer you add at the end. It's a design decision you make at the start and keep making throughout a service's lifetime. We help organisations build and maintain that posture through Secure by Design principles - at the edge, across the application, and into the network.
Our clearest technical differentiator: we're the first Authorised Service Delivery Partner across application security and SASE services for Cloudflare in EMEA, and one of their the most certified partners.
We've earned our depth across the full security stack through production deployments protecting national-scale services under real attack.
What we do
Edge and application security
Cloudflare-based protection across CDN, WAF, DDoS mitigation, bot management, and application performance. Deployed from the start of a build or retrofitted to an existing service. Our pre-built, pen-tested IaC/Terraform baseline means every engagement starts from a production-grade foundation.
Zero Trust Network Access (ZTNA)
Replacing legacy VPN with Cloudflare's ZTNA stack: Tunnels for application connectivity, Gateway for DNS and HTTP filtering, Warp for device-level security.
Access becomes identity-aware, continuously verified, and granular. We pilot with a discrete user group first, validate the access model, then expand. The ZTNA Pilot package is the right entry point for most clients.
IaC-managed Cloudflare estates
For clients with large or complex Cloudflare estates e.g. multiple accounts, hundreds of zones, configuration that has grown organically, our IaC migration capability is a distinct offer. New zones deployable in under an hour. Environment launches up to 80% faster. Environment-related issues reduced by 50%.
Secure Access Service Edge (SASE)
SASE combines traditional network security solutions (SWG, DLP, browser isolation, firewalls) in one dashboard, with services delivered at Cloudflare's edge. The addition of NaaS means all inbound and outbound network traffic between people, branches, locations, applications and infrastructure can safely and performantly proxy through Cloudflare's global network.
Identity and access management
Controlling who can access what, and proving it. We implement identity-aware access and integrate with whichever enterprise identity providers our clients rely on, from Entra ID and Okta to others, so access is granular, auditable and matched to risk.
Security architecture and advisory
Where the question goes beyond Cloudflare - threat modelling, security posture review, access control architecture, network segmentation - we bring independent, outcome-focused advisory. Tech-agnostic where it needs to be.
Why build with CDS?
We build for the real thing
The evidence base across our clients is national scale: 10 million daily users, 99.99% availability through 227 million peak requests, 100% uptime over multiple years, migrations completed in weeks without downtime.
We're full lifecycle, not just delivery
We build it, secure it, and run it. Clients get one accountable team from start to finish - not a delivery partner who hands over and walks away.
We start from the problem
Every engagement begins with a clear understanding of what the service needs to do and who it needs to serve. Technology follows that understanding, not the other way around.
AI is already part of how we deliver
We use AI-assisted development tools across our engineering teams. It makes our delivery faster, our code more consistent, and our teams more effective. We also build AI capability into the services we deliver: applied AI features, AI-enabled workflows, AI on the Cloudflare Developer Platform.
Accelerators in this area
Not every engagement starts with a big brief. Sometimes you just need a defined starting point with something scoped, fast and useful in its own right. These are our accelerators: fixed-scope pieces of work that give you something concrete to act on.
Cloud Audit
Assess, implement, migrate, and run your Cloud estate.
See our proof
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.
