Azure network architecture and security
Azure networking tends to grow by accident: a VNet here, a public IP there, and no clear segmentation or egress control. We design or remediate your Azure network the way it should be built: a hub-and-spoke or Virtual WAN topology, Azure Firewall controlling traffic between spokes and out to the internet, network security groups and application security groups enforcing least privilege, and private endpoints keeping platform services off the public internet.
What's included
- Topology design: hub-and-spoke or Azure Virtual WAN, region and availability-zone layout
- Azure Firewall or a third-party network virtual appliance, with Firewall Manager policy and forced tunneling where needed
- NSG and ASG design for micro-segmentation, with flow logs and traffic analytics
- Private endpoints and Private Link for storage, SQL, Key Vault, and other platform services
- Private DNS zones and name resolution across the estate
- Application Gateway with WAF, or Azure Front Door, for inbound web traffic
- DDoS Protection, and a review of every public IP and open port
- Site-to-site VPN or ExpressRoute connectivity to on-premises and other clouds
- Azure Bastion for admin access without public RDP or SSH
- Network diagrams and an operations runbook
How we work
Scope
A fixed statement of work: what we will do, what you receive, and the timeline. Agreed before any work starts.
Execute
We do the work in your tenant with least-privilege access, with updates at defined checkpoints, not radio silence.
Hand off
Documentation, runbooks, and a walkthrough so your team can operate what we built.
Azure Network Architecture & Security: common questions
Do you use Azure Firewall or a third-party firewall?
Either. Azure Firewall is the low-friction default and integrates with Firewall Manager. If you have standardized on Palo Alto, Fortinet, or Check Point, we design around a network virtual appliance instead.
How does this relate to the Azure Foundation Build?
The foundation build includes a basic networking baseline. This engagement is the full network design and security layer, for estates that have outgrown the basics or were never structured.
Can you connect Azure to our office?
Yes. Site-to-site VPN for most cases, ExpressRoute where you need dedicated bandwidth or lower latency. It pairs with the on-premises network engagement if the office side also needs work.
