CLOUD NETWORK ARCHITECTURE
Cloud Security & Networking – Secure by Design
A well-architected network is the foundation of a secure cloud environment. Without proper segmentation, access controls, and perimeter defences, even the most advanced application security can be undermined. Our Cloud Security and Networking services ensure that your Azure environment is designed from the ground up with defence in depth, Zero Trust principles, and robust connectivity that supports both performance and protection.
Our network architecture services begin with understanding your connectivity requirements. This includes connectivity between Azure resources, connectivity to on-premises environments, internet egress and ingress patterns, and connectivity for remote users. Based on these requirements, we design a hub-and-spoke or Virtual WAN network topology that provides proper segmentation, centralised security controls, and efficient routing. We configure Azure Virtual Networks, subnets, route tables, and peering connections to create a network architecture that is both secure and operationally efficient.
Network security is layered throughout the architecture. We implement Network Security Groups (NSGs) with least-privilege rules, deploy Azure Firewall or third-party network virtual appliances for advanced threat protection, configure Azure DDoS Protection to guard against volumetric attacks, and deploy Azure Web Application Firewall (WAF) to protect web-facing applications against common vulnerabilities such as SQL injection and cross-site scripting.
For organisations that need to connect their Azure environment to on-premises data centres or branch offices, we design and implement hybrid connectivity solutions using Azure VPN Gateway or Azure ExpressRoute. ExpressRoute provides dedicated, private connectivity to Azure that does not traverse the public internet, offering higher bandwidth, lower latency, and greater reliability. Our team works with your network providers to provision and configure these connections, ensuring seamless hybrid operations.
We also implement Zero Trust network access for remote users, leveraging Azure AD Conditional Access, Azure Private Link, and Azure Bastion to ensure that users can access the resources they need without exposing those resources to the public internet. This approach is fundamental to modern security architecture and is particularly important for organisations supporting remote and hybrid workforces.
Every network design we deliver includes comprehensive documentation, including network diagrams, IP address plans, firewall rule documentation, and operational runbooks. We also provide knowledge transfer to your internal teams and ongoing support to ensure that your network architecture evolves alongside your business needs.
