From hub-and-spoke topologies and ExpressRoute circuits to Azure Firewall policies and Private Endpoints — we design and build Azure networks that are secure, scalable, and deeply connected to your on-premises estate.
Network architecture, hybrid connectivity, firewalling, and private networking — the full stack of Azure networking.
End-to-end Azure network design using hub-and-spoke or Virtual WAN topologies. We plan your VNet address spaces, subnet segmentation, peering relationships, and NVA placement — building a network foundation that scales with your estate and never requires a painful re-address later. All designs are produced as IaC (Bicep or Terraform) before a single resource is deployed.
Reliable, high-bandwidth connectivity between Azure and your on-premises datacentres using ExpressRoute and VPN Gateway. We design and implement site-to-site VPN with BGP route exchange, redundant ExpressRoute circuits with failover, and point-to-site for remote access — ensuring that your hybrid workloads communicate with predictable latency and no single point of failure.
Centralised network security using Azure Firewall Premium with IDPS, TLS inspection, and URL filtering. We design rule collections and firewall policies as code, configure User Defined Routes to enforce traffic flows, deploy Azure DDoS Protection, and integrate Azure Web Application Firewall (WAF) with Application Gateway or Front Door — giving you defence-in-depth at every network boundary.
Private DNS zones, Azure DNS Private Resolver, and Private Endpoints for every PaaS service — eliminating public exposure for storage, databases, Key Vault, and more. We configure split-horizon DNS so on-premises clients resolve private endpoints correctly through your hybrid link, and design name resolution that works seamlessly across Azure regions and on-premises environments without manual host file management.
How we design and build networks that are right the first time.
Topology workshops to agree hub-and-spoke vs. Virtual WAN, address space allocation, and on-premises integration patterns. Produce architecture diagrams and ADRs before any IaC is written. No resources deployed until the design is signed off.
Deploy hub VNet, Azure Firewall, DNS Private Resolver, and gateway resources using modular Bicep or Terraform. Spoke VNets and peering relationships follow in a controlled sequence, with connectivity validated at each step before moving forward.
Establish hybrid connectivity — VPN tunnels or ExpressRoute circuits — and validate BGP route advertisement and failover behaviour. Test name resolution end-to-end from on-premises through the hybrid link to Private Endpoints in Azure.
Monitor traffic flows with Network Watcher, Connection Monitor, and Azure Monitor. Tune firewall policies as workloads evolve. Manage route tables and NSG rules as code, reviewed and deployed through the same CI/CD pipeline as everything else.
