We recently announced the general availability of Microsoft Defender for SQL to protect SQL Servers in Azure, on premises, and in multi-cloud deployments on Amazon Web Services (AWS) and Google Cloud Platform (GCP). Today we are happy to announce we are expanding Microsoft Defender for Cloud’s SQL protection to open-source relational databases. Microsoft Defender for open-source relational databases is now generally available for use with Azure Databases for MySQL, PostgreSQL, and MariaDB single servers. 

Attackers often laterally traverse within organizations to discover and exfiltrate data, wherever it is stored, making open-source databases and SQL Server common targets. With Microsoft Defender for Cloud, you can now protect your SQL Servers, as well as your open-source databases, expanding and strengthening your protection across your entire SQL estate. We recommend you protect your production instances of SQL and open-source databases with Microsoft Defender for Cloud as part of your overall security strategy.
