Azure Firewall Pricing

Azure Firewall cost = a fixed hourly charge per firewall + a per-GB data processing charge. Compare the Basic, Standard and Premium tiers, estimate your cost and learn how to save. This Azure Firewall Pricing guide keeps it simple.

⚡ Short answer

Azure Firewall pricing has two main parts: a fixed hourly deployment charge for each firewall and a data processing charge per GB. The hourly rate depends on the tier — Basic (lowest), Standard or Premium (highest, adds TLS inspection and IDPS). Use one shared firewall in a hub-and-spoke design to keep costs down.

The basics

What is Azure Firewall?

A stateful, managed firewall-as-a-service with built-in high availability and auto-scaling. It filters traffic between your VNets, the internet and on-premises using:

🔢

Network rules

Allow or deny by IP, port and protocol.

🌐

Application (FQDN) rules

Allow outbound traffic to specific domains.

🧠

Threat intelligence

Alert on or block known malicious IPs and domains.

How Azure Firewall pricing works

⏱️

Deployment charge

Fixed price per firewall per hour. Basic < Standard < Premium.

📶

Data processed

Charged per GB the firewall processes.

➕

Related costs

Public IPs, Firewall Manager policies, secured virtual hubs and cross-region transfer.

Rates vary by region and change — check the official Azure Firewall pricing page.

Ways to reduce Azure Firewall costs

•  Use hub-and-spoke so one firewall protects many VNets

•  Pick Basic for small, low-traffic environments

•  Use Premium only where you need TLS inspection or IDPS

•  Do not route traffic through the firewall that needs no inspection

•  Stop and deallocate non-production firewalls when unused

•  Review traffic and costs in Azure Cost Management

Azure Firewall vs network security groups (NSGs)

🚦 NSGs

•  Free

•  Basic allow/deny rules

•  Applied to subnets and NICs

•  No FQDN rules or threat intel

🧱 Azure Firewall

•  Paid service

•  Central control across many VNets

•  Application (FQDN) rules and threat intelligence

•  Full logging

✅ ✅ Best practice: Most designs use both. Learn more in Azure virtual networks.

Frequently asked questions

What affects Azure Firewall pricing?

Mainly the tier (Basic, Standard, Premium), how many firewalls you run and for how many hours, and how many GB of data they process. Region and related resources also matter.

What are the Azure Firewall tiers?

There are three: Basic, Standard and Premium. Premium adds TLS inspection, IDPS and URL filtering.

Is Azure Firewall charged when idle?

Yes, the hourly deployment charge applies while it is deployed. Deallocate non-production firewalls when not needed.

Where can I find current prices?

On Microsoft’s official Azure Firewall pricing page, or by using the Azure Pricing Calculator for your region.

Do I still need NSGs with Azure Firewall?

Usually yes. NSGs handle subnet-level rules for free, and the firewall gives central, advanced filtering.
