The document discusses the OWASP Open Security Summits, which are conferences that have been held since 2008. They provide a place for OWASP leaders to meet, collaborate, and build relationships. The summits feature working sessions on security topics and have resulted in the incubation of future OWASP leaders. In 2018, the name was changed to the Open Security Summit. The document requests that OWASP sponsor attendance at the 2019 summit by buying tickets for OWASP leaders, as they have done in previous years.
