Celebrating its 20th anniversary, the Open Web Application Security Project (OWASP) continues to be a pivotal open-source resource in web security, providing developers with vital methodologies, best practices, tools, and intelligence. Known for the widely-referenced OWASP Top Ten list that highlights critical web application vulnerabilities, the project has recently updated the list for the first time since 2017, marking a significant change by renaming "Sensitive Data Exposure" to "Cryptographic Failures" to better address the root causes of vulnerabilities. The Foundation is hosting a free 24-hour global event and actively encourages feedback and peer-reviews from the open-source community to continuously refine its resources. Over the past two decades, OWASP has significantly influenced the web security landscape, guiding developers through the complexities of evolving applications, and continues to inspire contributions from organizations like GitGuardian.
