The Open Web Application Security Project (OWASP) is a nonprofit organization focused on improving the security of software. It provides resources, tools, and guidelines to help developers and organizations create secure web applications. One of its key initiatives is the annual release of the OWASP Top Ten, which highlights the most critical security risks to web applications. Founded in 2001, OWASP aims to educate and raise awareness about web application security. It offers a variety of projects, including documentation, training, and community-driven events, to support developers and security professionals in building safer applications.
