What Is Azure Firewall?
Azure Firewall is a managed, cloud-native network security service designed to protect resources deployed within Azure Virtual Networks. Unlike traditional perimeter-based firewalls, it scales automatically with your workloads, requires no infrastructure maintenance, and integrates natively with Microsoft's broader security ecosystem.
It supports both inbound and outbound traffic filtering, internal spoke-to-spoke connections, and hybrid connectivity through Azure VPN and ExpressRoute gateways - making it a versatile choice for complex, multi-network enterprise environments.

- Automatically blocks traffic to and from known malicious IP addresses and domains
- Draws on real-time threat signals from Microsoft's global intelligence network
- Defends against zero-day vulnerabilities and rapidly evolving attack vectors
TLS Inspection and Malware Prevention
- Decrypts outbound traffic, performs security checks, then re-encrypts before forwarding
- Prevents malware and viruses from spreading through encrypted connections
- Works alongside URL filtering and web category controls to restrict access to high-risk or non-compliant websites
Intrusion Detection and Prevention (IDPS)
- Monitors network traffic using a library of more than 58,000 threat signatures across 50-plus categories
- Detects and optionally blocks attacks across all ports and protocols
- Signature database is updated continuously to address new and emerging exploits, including malware, phishing, coin mining, and Trojan attacks
Centralized Policy Management

Azure Firewall Tiers: Standard vs. Premium
Organizations can choose between two service tiers based on their security requirements:
- Azure Firewall Standard - Delivers core firewall capabilities including threat intelligence filtering, network and application rule collections, and Azure Monitor integration. Well-suited for most enterprise workloads.
- Azure Firewall Premium - Adds advanced capabilities including TLS inspection, IDPS, and URL filtering. Designed for highly sensitive and regulated industries such as financial services and healthcare where deeper inspection and stricter compliance are required.

Common Use Cases
Securing Hybrid and Multi-Cloud Environments
Organizations extending on-premises infrastructure to Azure can use Azure Firewall to enforce consistent security policies across VPN and ExpressRoute connections, ensuring that hybrid connectivity does not introduce security gaps.
Protecting Regulated Workloads
Industries subject to compliance frameworks such as HIPAA, PCI DSS, or ISO 27001 benefit from Azure Firewall Premium's advanced inspection capabilities and detailed logging, which support audit requirements and demonstrate due diligence.
Controlling East-West Traffic
Azure Firewall can inspect and control lateral traffic between virtual network spokes, reducing the risk of threats spreading within your environment after an initial compromise.
Filtering Outbound Internet Access
IT teams can restrict which applications and users can access the internet, block access to risky web categories, and deny connections to known malicious destinations - all from a central policy configuration.
Private Endpoint Traffic Inspection
Azure Firewall supports inspection of traffic destined for private endpoints, giving security teams visibility and control over communication between virtual network resources and private link services.

Azure Firewall Pricing
Azure Firewall uses a straightforward consumption-based pricing model with no upfront costs or termination fees. Billing includes a fixed hourly rate plus variable charges based on data processed. Organizations can also take advantage of Azure credits and free account benefits when getting started.
TechPower can help you model expected costs based on your traffic patterns and security requirements, so there are no surprises on your monthly bill.
