Microsoft Expands Bug Bounties Across All Products

Microsoft is shaking up the cybersecurity world with a major update to its bug bounty program. Starting now, security researchers can submit critical vulnerability reports for any Microsoft product or service—even those without formal payouts. This move, known as the “In Scope by Default” approach, aims to encourage more researchers to identify and report security flaws, keeping Microsoft’s ecosystem safer for everyone.

‘In Scope by Default’ Explained

The new policy, unveiled by Tom Gallagher, Engineering VP at Microsoft Security Response Center, at Black Hat Europe, removes previous limits on which products are eligible for bounty submissions. Whether it’s proprietary software, third-party tools, or open-source code, researchers can now flag vulnerabilities that impact Microsoft services. This shift marks a more inclusive and proactive approach to cybersecurity.

Microsoft’s Record Payouts

Last year, Microsoft paid out more than $17 million in bug bounties, surpassing Google’s total payouts. These rewards went to researchers who uncovered high-impact vulnerabilities affecting Microsoft-owned domains, online services, and critical third-party code. With the new expansion, these payouts could potentially grow even larger, as more programs and services fall under bounty eligibility.

Encouraging Security Research

By opening the door to all products, Microsoft hopes to foster a stronger security research community. Researchers often hesitate to report bugs without guaranteed compensation. This inclusive policy removes that barrier, incentivizing experts to report vulnerabilities before they are exploited by malicious actors. The initiative reflects Microsoft’s commitment to proactive cybersecurity.

Third-Party and Open Source Coverage

Microsoft’s bug bounty expansion also applies to third-party and open-source code linked to its ecosystem. Vulnerabilities in these areas can now be submitted under the bounty program, which increases the overall security posture of Microsoft’s products. This approach acknowledges the interconnected nature of today’s software environment.

Industry Implications

The “In Scope by Default” initiative could set a new industry standard. By offering bounties even on previously excluded programs, Microsoft positions itself as a leader in proactive vulnerability management. Competitors may feel pressure to adopt similar strategies to maintain trust and security credibility.

As the program rolls out, researchers and organizations alike are expected to closely monitor Microsoft’s expanded bug bounty policies. The company’s commitment to rewarding critical security discoveries—even in previously excluded areas—signals a strong focus on protecting users and fostering innovation in the cybersecurity space.
