Protect against cyberattacks with the new Azure Firewall Basic

Cyberattacks continue to rise across businesses of all sizes as attackers are adapting their techniques and increasing the complexity of their operations.1 The risk of these attacks is significant for small and medium businesses (SMBs) as they usually don’t have the specialized knowledge or resources to protect against emerging threats and face more challenges when recovering from an attack. In a recent Microsoft survey,2 70 percent of SMBs think cyberthreats are becoming more of a business risk and nearly one in four SMBs stated that they had a security breach in the last year.

SMBs need solutions that are tailored to their unique needs and challenges. Microsoft is committed to delivering security solutions to meet the needs of all our customers. We are excited to announce the general availability of Azure Firewall Basic, a new SKU of Azure Firewall built for SMBs.

Since public preview, we have seen a wide adoption of the Azure Firewall Basic. Customers stated the simplicity and ease of use of the Azure Firewall as one of the key benefits for choosing Azure Firewall Basic.  We have also added the capability to deploy Azure Firewall inside a virtual hub in addition to a virtual network. This gives businesses the flexibility to choose the deployment option that best meets their needs.

Deploying Azure Firewall in a virtual network is recommended for customers who plan to use traditional hub-and-spoke network topology with a Firewall on the hub. Whereas, deploying on a virtual hub is recommended for customers with large or global network deployments in Azure where global transit connectivity across Azure regions and on-premises locations is needed.

Providing SMBs with a highly available Firewall at an affordable price point


Azure Firewall Basic brings the simplicity & security of Azure Firewall to SMBs at a cost-effective price point

It offers Layer 3–Layer 7 filtering and alerts on malicious traffic with built-in threat intelligence from Microsoft threat intelligence. As a cloud-native service, Azure Firewall Basic is simple to deploy with a few clicks and seamlessly integrates with other Azure services, including Microsoft Azure Firewall Manager, Azure Monitor, Azure Events Hub, Microsoft Sentinel, and Microsoft Defender for Cloud.

Key features of Azure Firewall Basic


Comprehensive, cloud-native network firewall security

◉ Network and application traffic filtering—Centrally create, allow, or deny network filtering rules by source and destination IP address, port, and protocol. Azure Firewall is fully stateful, so it can distinguish legitimate packets for different types of connections. Rules are enforced and logged across multiple subscriptions and virtual networks.
◉ Threat intelligence to alert on malicious traffic—Enable threat intelligence-based filtering to alert on traffic from or to known malicious IP addresses and domains. The IP addresses and domains are sourced from the Microsoft threat intelligence feed.
◉ Built-in high availability—Azure Firewall Basic provides built-in high availability to ensure that your network traffic is always protected. Azure Firewall Basic can replicate your firewall instance across two availability zones, ensuring that your traffic is always filtered even if one of the zones goes down.

Simple setup and easy to use

◉ Set up in just a few minutes—Use the Quickstart deployment Azure Resource Manager (ARM) templates to easily deploy Azure Firewall Basic directly to your Azure environment.
◉ Automate deployment (deploy as code)—Azure Firewall Basic provides native support for Infrastructure as Code (IaC). Teams can define declarative ARM templates that specify the infrastructure required to deploy solutions. Third-party platforms like Terraform also support IaC to manage automated infrastructure.
◉ Zero maintenance with automatic updates—Azure Firewall is automatically updated with the latest threat intelligence and security updates to ensure that it stays up-to-date and protected against the latest threats.
◉ Centralized management via Azure Firewall Manager—Azure Firewall Manager is a central management solution that allows you to manage multiple Azure Firewall instances and policies across your organization from a single location, ensuring that your security policies are consistent and up to date across your organization.
