Microsoft Bug Bounty Program

Microsoft strongly believes close partnerships with the global security researcher community make customers more secure. Security researchers play an integral role in the ecosystem by discovering vulnerabilities missed in the software development process and sharing them under Coordinated Vulnerability Disclosure (CVD). Each year we partner together to better protect billions of customers worldwide.

If you are a security researcher that has found a vulnerability in a Microsoft product, service, or device we want to hear from you. If your vulnerability report affects a product or service that is within scope of one of our bounty programs below, you may receive a bounty award according to the program descriptions. Even if it is not covered under an existing bounty program, we will publicly acknowledge your contributions when we fix the vulnerability. All vulnerability submissions are counted in our Researcher Recognition Program and Researcher Leaderboard, even if they do not qualify for bounty award.
