We are an open community dedicated to enabling organizations to conceive, develop, acquire, operate, and maintain applications that can be trusted. All of our projects, tools, documents, forums, and chapters are free and open to anyone interested in improving application security. The OWASP Foundation launched on December 1st, 2001, becoming incorporated as a United States non-profit charity on April 21, 2004.
