Each year, as global threats to cybersecurity grow ever more sophisticated, the digital world’s frontline defenders quietly make their impact felt. Microsoft’s Security Response Center (MSRC) has again stepped forward to celebrate those tireless and ingenious individuals by unveiling its list of the 2025 Most Valuable Security Researchers (MVRs). This ambitious recognition program not only shines a light on the invaluable role of security researchers in safeguarding countless users and infrastructures worldwide, but also underscores the complex ecosystem of collaboration, incentive, and expertise essential to modern cyber defense.
Microsoft’s Researcher Recognition Program is built upon the philosophy of coordinated vulnerability disclosure (CVD). By fostering a transparent, incentive-driven platform for third-party researchers to report security vulnerabilities, Microsoft ensures that flaws are addressed responsibly—well before bad actors can exploit them. The MSRC received thousands of vulnerability reports between July 2024 and June 2025, and its annual leaderboard highlights those researchers who have had the greatest impact on the company’s ability to protect its customers.
This public acknowledgment comes with more than just praise. Researchers topping the list receive digital badges, community recognition, and even bespoke swag, designed to both reward dedication and encourage a spirit of healthy competition. The synergy between Microsoft and the broader security community is plain to see: without these independent experts scrutinizing Windows, Azure, Office, Dynamics 365, and more, the company would be far less equipped to respond rapidly to emerging threats.
Beyond the main Top 100 list, MSRC also runs product-specific technical leaderboards. These segment recognition further, highlighting individuals whose discoveries have had particularly high impact within key Microsoft technology ecosystems. For example, the 2025 leaderboards publicly celebrated the top researchers for Azure, Office, Windows, and Dynamics 365/Power Platform. Standouts include Suresh Chelladurai and Adnan in Azure, 0x140ce and Haifei Li in Office, as well as wkai and VictorV in Windows.
Such scalable, merit-based recognition not only reinforces fairness but also promotes accountability within Microsoft’s security response. Researchers gain a clear understanding of how their work is measured, and the transparency of the point system discourages low-quality or incomplete submissions.
In the 2025 leaderboard, the Azure category was dominated by Suresh Chelladurai and Adnan, two names recognized for their persistent excellence in identifying cloud service vulnerabilities. Meanwhile, the Office leaderboards saw 0x140ce and Haifei Li taking the lead, with strong showings from Guang Gong, Li Shuang, and willJ—reflecting a mix of well-established experts and rising talents.
The Windows product, core to Microsoft’s global ecosystem, likewise saw innovation from wkai and VictorV. Less mainstream, but equally vital, is the Dynamics 365 and Power Platform category, where this year Dhiral Patel, Brad Schlintz, and the research teams from Kunlun Lab and HUST made indelible marks. Their work has direct consequences for enterprise security, data integration, and business process automation.
A closer look at past years’ lists reflects the increasingly international flavor of the competition. Whereas early vulnerability disclosure programs were more U.S.-centric, today’s leaderboards showcase researchers—and research teams—from around the globe, illustrating cybersecurity’s truly borderless nature.
Furthermore, a timely email from msrcmvr@microsoft.com guides researchers through the process of claiming their rewards, reinforcing a sense of ceremony and accomplishment. Such visibility not only feels good to individual contributors, but also signals to recruiters and employers that these are professionals who have made significant, validated impacts on Microsoft’s security ecosystem.
This coordination isn’t merely for Microsoft’s benefit. For researchers, it offers both legal protection and public credit. For consumers and enterprises, it translates directly to increased security and confidence in the platforms they rely upon.
But CVD has its critics. Some argue that vendors’ patch timelines can be too slow, or that bug bounties don’t always scale to the true market value of a high-severity bug—especially given the lucrative and ethically ambiguous exploits market. Microsoft’s leaderboard, by attaching quantifiable recognition and additional rewards to swift, actionable, high-quality disclosures, seeks to tilt the playing field toward responsible disclosure and away from gray markets.
Moreover, these programs serve an important pedagogical role. By highlighting the methods, tools, and ethical standards valued by Microsoft, the MSRC indirectly influences how educational institutions, startups, and government agencies train their own security practitioners.
Responsibly disclosing a software flaw is no longer a purely academic or technical exercise—it is a collaborative, highly incentivized, globally recognized endeavor.
Artificial intelligence and machine learning, for example, now underpin both cyberattacks and defense strategies. It is likely only a matter of time before MSRC creates specialized leaderboards for AI-related security research, or introduces even more granular distinctions among types of vulnerabilities.
Meanwhile, as the digital estate widens via edge computing, IoT, and hybrid-cloud deployments, Microsoft’s need for a robust, global, and continually motivated research community will only intensify.
As cyber threats multiply and diversify, the company’s embrace of community-led security is both pragmatic and, in many ways, necessary. For researchers, the chance to feature on Microsoft’s prestigious leaderboard is not just a badge of honor—but increasingly, a vital part of professional development and industry influence.
While potential pitfalls remain, the MSRC’s program succeeds in channeling global talent toward the public good, reducing risk across Microsoft’s vast product ecosystem, and elevating the standards for the security industry as a whole. As the digital age races forward, it will be these collaborative, recognition-driven models that shape the future of cybersecurity.

Microsoft’s Approach to Collaborative Security
Microsoft’s Researcher Recognition Program is built upon the philosophy of coordinated vulnerability disclosure (CVD). By fostering a transparent, incentive-driven platform for third-party researchers to report security vulnerabilities, Microsoft ensures that flaws are addressed responsibly—well before bad actors can exploit them. The MSRC received thousands of vulnerability reports between July 2024 and June 2025, and its annual leaderboard highlights those researchers who have had the greatest impact on the company’s ability to protect its customers.This public acknowledgment comes with more than just praise. Researchers topping the list receive digital badges, community recognition, and even bespoke swag, designed to both reward dedication and encourage a spirit of healthy competition. The synergy between Microsoft and the broader security community is plain to see: without these independent experts scrutinizing Windows, Azure, Office, Dynamics 365, and more, the company would be far less equipped to respond rapidly to emerging threats.
Metrics and Recognition: How the MVRs Are Ranked
A significant strength of the MSRC’s program lies in its transparent and quantitative approach. Researchers accumulate points for each valid vulnerability they responsibly disclose. Only verified and actionable reports are eligible, ensuring that “volume” isn’t rewarded at the expense of thoroughness or clarity. The ranking period for the 2025 awards covered July 1, 2024, through June 30, 2025—a timeframe reflecting the fast-moving nature of the cybersecurity landscape.Beyond the main Top 100 list, MSRC also runs product-specific technical leaderboards. These segment recognition further, highlighting individuals whose discoveries have had particularly high impact within key Microsoft technology ecosystems. For example, the 2025 leaderboards publicly celebrated the top researchers for Azure, Office, Windows, and Dynamics 365/Power Platform. Standouts include Suresh Chelladurai and Adnan in Azure, 0x140ce and Haifei Li in Office, as well as wkai and VictorV in Windows.
Such scalable, merit-based recognition not only reinforces fairness but also promotes accountability within Microsoft’s security response. Researchers gain a clear understanding of how their work is measured, and the transparency of the point system discourages low-quality or incomplete submissions.
Badge Achievements: Accuracy, Impact, and Volume
Another notable feature of the MSRC program is its badge system, designed to spotlight researchers’ unique approaches and strengths. Three badges are awarded each year:- Accuracy Badge: For those who maintained 100% accuracy, with every submission resulting in a validated vulnerability report. This is particularly prestigious, as even seasoned researchers occasionally submit edge-case or duplicate reports that don’t ultimately qualify.
- Impact Badge: Intended for researchers whose average points per vulnerability place them in the top decile, highlighting the significance and potential severity of their discoveries.
- Volume Badge: For those submitting at least five valid vulnerability reports during the judging period, acknowledging the tremendous effort and persistence required to uncover multiple distinct threats.
Highlights from the 2025 Technical Leaderboards
The annual technical leaderboards offer a fascinating glimpse into both the specialization and diversity of the security research community. Unsurprisingly, Azure and Office remain hot zones for vulnerability discovery. The prominence of cloud and productivity platforms as critical infrastructure means even minor security flaws can have major implications for businesses and individuals.In the 2025 leaderboard, the Azure category was dominated by Suresh Chelladurai and Adnan, two names recognized for their persistent excellence in identifying cloud service vulnerabilities. Meanwhile, the Office leaderboards saw 0x140ce and Haifei Li taking the lead, with strong showings from Guang Gong, Li Shuang, and willJ—reflecting a mix of well-established experts and rising talents.
The Windows product, core to Microsoft’s global ecosystem, likewise saw innovation from wkai and VictorV. Less mainstream, but equally vital, is the Dynamics 365 and Power Platform category, where this year Dhiral Patel, Brad Schlintz, and the research teams from Kunlun Lab and HUST made indelible marks. Their work has direct consequences for enterprise security, data integration, and business process automation.
A closer look at past years’ lists reflects the increasingly international flavor of the competition. Whereas early vulnerability disclosure programs were more U.S.-centric, today’s leaderboards showcase researchers—and research teams—from around the globe, illustrating cybersecurity’s truly borderless nature.
Incentives and Rewards: Swag, Digital Badges, and Beyond
Beyond community prestige and the technical badge system, honorees of the MSRC MVR distinction receive tangible rewards. For 2025, the Top 100 MVRs are promised an exclusive MSRC swag box—a now-coveted staple of the community—along with digital badges for social media and professional portfolios. These digital tokens serve as both conversation starters and career credentials, amplifying the reputations of recipients in a crowded, competitive field.Furthermore, a timely email from msrcmvr@microsoft.com guides researchers through the process of claiming their rewards, reinforcing a sense of ceremony and accomplishment. Such visibility not only feels good to individual contributors, but also signals to recruiters and employers that these are professionals who have made significant, validated impacts on Microsoft’s security ecosystem.
Coordinated Vulnerability Disclosure: The Bedrock Principle
At the program’s heart is the practice of Coordinated Vulnerability Disclosure. This approach establishes clear guidelines for timelines, communications, and responsibilities when vulnerabilities are discovered. By funneling security reports through the MSRC and collaborating on fixes prior to any public disclosure, Microsoft maximizes the chance to patch flaws before they’re exploited in the wild.This coordination isn’t merely for Microsoft’s benefit. For researchers, it offers both legal protection and public credit. For consumers and enterprises, it translates directly to increased security and confidence in the platforms they rely upon.
But CVD has its critics. Some argue that vendors’ patch timelines can be too slow, or that bug bounties don’t always scale to the true market value of a high-severity bug—especially given the lucrative and ethically ambiguous exploits market. Microsoft’s leaderboard, by attaching quantifiable recognition and additional rewards to swift, actionable, high-quality disclosures, seeks to tilt the playing field toward responsible disclosure and away from gray markets.
The Risks and Realities of an Outsourced Security Ecosystem
While applauding the virtues of the MSRC’s collaborative model, it’s important to assess risks and complexities inherent in outsourcing parts of a company’s security posture to external researchers:- Signal-to-Noise Ratio: As bug bounty and recognition programs expand, so does the volume of reports—many of which can be duplicates or low priority. Filtering high-impact from low-value submissions requires substantial triage resources and constant evolution of automation tools.
- Researcher Motivation: While badges and swag foster community and engagement, some vulnerabilities are so valuable on the open market—particularly zero-days in major cloud platforms—that researchers (especially from less-regulated countries) may weigh responsible disclosure against private financial incentives.
- Legal and Political Risks: Coordinated disclosure demands trust. There have been documented instances across the industry of researchers’ discoveries leading to legal pushback, delayed recognition, or inadequate communication. Microsoft’s clear communication around rewards and badges, and the public nature of its leaderboard, tentatively mitigate—but do not eliminate—these risks.
Beyond the Leaderboard: Impact on the Broader IT Industry
Microsoft’s public recognition of its MVRs is part of a broader shift toward openness and partnership between vendors and the security research community. As tech companies increasingly embrace this model, the standard for software and cloud platform security continues to rise, benefitting businesses, governments, and end-users alike.Moreover, these programs serve an important pedagogical role. By highlighting the methods, tools, and ethical standards valued by Microsoft, the MSRC indirectly influences how educational institutions, startups, and government agencies train their own security practitioners.
Responsibly disclosing a software flaw is no longer a purely academic or technical exercise—it is a collaborative, highly incentivized, globally recognized endeavor.
Looking Forward: The Future of Security Research Recognition
As the threats facing cloud services, operating systems, and enterprise platforms evolve—often outpacing traditional response mechanisms—so too must Microsoft’s approach to security partnerships. Expect future iterations of the MSRC program to further diversify badge criteria, expand technological focus areas, and deepen incentives for ethical, high-impact disclosures.Artificial intelligence and machine learning, for example, now underpin both cyberattacks and defense strategies. It is likely only a matter of time before MSRC creates specialized leaderboards for AI-related security research, or introduces even more granular distinctions among types of vulnerabilities.
Meanwhile, as the digital estate widens via edge computing, IoT, and hybrid-cloud deployments, Microsoft’s need for a robust, global, and continually motivated research community will only intensify.
Conclusion: The Value of Ethical Security Collaboration
The MSRC’s 2025 Most Valuable Security Researchers list exemplifies what is possible when a technology giant leverages not just its own expertise, but the collective intelligence of security researchers worldwide. Through transparent metrics, meaningful incentives, and public recognition, Microsoft continues to set a benchmark for responsible vulnerability disclosure and collaborative cyber defense.As cyber threats multiply and diversify, the company’s embrace of community-led security is both pragmatic and, in many ways, necessary. For researchers, the chance to feature on Microsoft’s prestigious leaderboard is not just a badge of honor—but increasingly, a vital part of professional development and industry influence.
While potential pitfalls remain, the MSRC’s program succeeds in channeling global talent toward the public good, reducing risk across Microsoft’s vast product ecosystem, and elevating the standards for the security industry as a whole. As the digital age races forward, it will be these collaborative, recognition-driven models that shape the future of cybersecurity.
