Microsoft launches Defender Bounty Program with $20,000 rewards

Microsoft has unveiled a new bug bounty program aimed at the Microsoft Defender security platform, with rewards between $500 and $20,000.

Currently, the Microsoft Defender Bounty Program is limited in scope and will focus solely on Microsoft Defender for Endpoint APIs.

“The Microsoft Defender Bounty Program invites researchers across the globe to identify vulnerabilities in Defender products and services and share them with our team,” said MSRC Senior Program Manager Madeline Eckert.

If a submission qualifies for multiple bounty programs, the researchers will receive the highest single payout reward from a single bounty program.

Last year, Redmond added on-premises Exchange, SharePoint, and Skype for Business to its bug bounty program and increased the maximum awards for high-impact security flaws reported through its Microsoft 365 program.

New Microsoft bug bounty program focuses on AI-powered Bing.
