Due to the acceleration of digital transformation and the increase in hybrid work, organizations are seeing an increase in the quantity and sophistication of cyberattacks. While businesses of all sizes confront similar security concerns, the development of remote work and new digital business models has made cybersecurity a key concern for small and medium-sized enterprises (SMBs). SMBs are particularly at risk because of their limited resources and a lack of professional security capabilities. According to a recent study, more than 60% of small businesses suffered a cyberattack and were made unavailable, , highlighting the importance of solutions like Azure Firewall Basic.

Microsoft is always coming up with new ideas to help secure customers’ digital assets in a changing, dangerous environment and support SMB users as they migrate to the cloud. They are excited to present the Azure Firewall Basic preview today.

A new SKU of Azure Firewall called Azure Firewall Basic was created to meet the requirements of SMBs by offering cost-effective enterprise-grade protection for their cloud environment. A stateful firewall as a service that is cloud-native, highly available, and allows users to centrally manage and report all of their traffic flows offers important aspects at scale.

Enterprise-grade security that is cost-effective and built for SMBs

It comes with built-in threat intelligence from Microsoft Threat Intelligence, Layer 3-Layer 7 filterings, and warnings on malicious traffic. You can gain more visibility into your environment, recognize threats more quickly, and respond to them thanks to close interaction with other Azure services like Azure Monitor, Azure Events Hub, Microsoft Sentinel, and Defender for Cloud.
