The Open Web Application Security Project (OWASP) is a non-profit, community-driven organization that serves as a cornerstone of modern Application Security (AppSec). It produces a wide array of freely available articles, methodologies, documentation, tools, and technologies designed to help developers and organizations build and maintain secure software. Central to its mission are globally recognized projects like the OWASP Top 10, which raises awareness of the most critical web application security risks, and the Application Security Verification Standard (ASVS), which provides a basis for testing technical security controls. By creating and maintaining these practical standards and resources, OWASP provides a foundational framework for identifying, mitigating, and preventing vulnerabilities throughout the entire software development lifecycle.
