Microsoft is committed to ensuring our cloud is secure from modern threats and we built Azure with security in mind from the beginning. We work hard to earn your trust in the cloud, but we don’t do it alone. Security researchers have repeatedly demonstrated that working together helps protect customers by identifying and reporting vulnerabilities to Microsoft through Coordinated Vulnerability Disclosure (CVD).

The Azure Security Lab provides additional resources, environments, and tooling to help security researchers explore and research for high impact vulnerabilities in the cloud. Security researchers will have the opportunity to participate in limited time research challenges and earn awards specific to each research challenge.

This bounty program is subject to these terms and those outlined in the Azure Bounty Program and Microsoft Bounty Terms and Conditions


Coming soon. More information will be published when new research challenges become available.
