The Open Web Application Security Project (OWASP) is a worldwide free and open community focused on improving the security of application software. There are over 200 OWASP Local Chapters world-wide that are free and open to anyone to attend. OWASP tools and documents can be used to detect and to guard against security-related design and implementation flaws, as well as to add security-related activities into your Software Development Life Cycle (SDLC).

For additional detail about OWASP, leadership, and corporate details, please refer to the About OWASP page.

Featured projects include:

  • OWASP Top Ten Project - The OWASP Top Ten provides a powerful awareness document for web application security. The OWASP Top Ten represents a broad consensus about what the most critical web application security flaws are.

OWASP's philosophy is that achieving security involves all parts of an organization, including people, process, and technology. We support the use of our brand consistent with this philosophy. However, we cannot allow the use of our brand when it implies something inconsistent with OWASP's comprehensive and balanced approach to application security. Therefore, we have defined these brand usage rules to clarify appropriate and inappropriate uses of the OWASP brand, including our name, domain, logos, project names, and other trademarks. The Brand Guidelines document can be found on the Brand Resources page.
