In today’s interconnected world, cyber attacks and data breaches pose significant threats to personal privacy, commerce, and national security. Microsoft software and cloud products are among the most commonly used by businesses, governments, and individuals, making them attractive targets for cybercriminals and hostile state actors who seek to exploit Microsoft’s user base in order to attempt large-scale disruptions and data theft.

Microsoft Vulnerability Tracker is an effort supported by NetChoice and informed by numerous experts and organizations to catalog Microsoft’s growing list of cybersecurity vulnerabilities to highlight the scope and magnitude of this threat, the risks of overdependence on Microsoft, and the need to end vendor lock on government software contracts.
