What We Cover

Network architecture
and access controls.

Define where traffic needs to flow, where it should be restricted and how the network will be operated and maintained.

01

Azure network architecture

Build clear network boundaries around your cloud workloads. We design Azure Virtual Network layouts, routing and private access around your applications and their dependencies.

  • Virtual networks, subnet design and address planning
  • Hub-and-spoke architecture, peering and routing
  • Network security groups and workload segmentation
  • Azure Private Link, private endpoints and DNS design
02

Azure Firewall and traffic controls

Define which connections are permitted, restrict unnecessary exposure and make firewall policies easier to maintain. We design and configure Azure Firewall controls to match your traffic requirements.

  • Firewall architecture and configuration planning
  • Application and network rule design
  • Inbound and outbound traffic controls
  • Administrative access, logging and configuration backup
03

Hybrid connectivity and secure access

Connect your existing environment to Microsoft Azure with secure, documented network paths. We assess Azure VPN Gateway options and design connectivity around your access and resilience requirements.

  • Site-to-site VPN and hybrid connectivity design
  • Remote access requirements and authentication controls
  • Separation of users, servers and management networks
  • Connectivity dependencies for disaster recovery
04

Implementation and operational handover

Plan the migration, test connectivity and security rules, and document the configuration for ongoing administration.

  • Migration and change plans with rollback steps
  • Connectivity, access-rule and resilience testing
  • Network diagrams and configuration records
  • Monitoring requirements and maintenance procedures
