Founded in 2001 as an open-source security community centered around the goal of spreading application security awareness, the Open Web Application Security Project (OWASP) is most famous for their OWASP Top 10 which has become the industry gold standard for application security.

Powered by a global network of over 42,000 security-aware volunteers, OWASP members hail from educational and government institutions, large corporations and more. This highly active community produces content, organizes events, and publishes articles, methodologies, tools and technologies which are free and available to everyone. All OWASP projects and events are managed and backed by the OWASP Foundation which is a 501(c)(3) charitable organization.

One of the factors that allows OWASP to produce such high quality application security content without any inherent biases is the fact that OWASP is not affiliated with any specific organization, although it receives support from its active community members.
