California
Oakland itself has few security meetings of its own: the Sudo Room hackerspace runs open hack nights several evenings a week, and DC510 meets on a Sunday each month near Ashby BART on the Berkeley line. Most professional chapters serving the East Bay meet in San Francisco, the Tri-Valley or Silicon Valley, or online, such as ISC2 East Bay's monthly Zoom talks. The area's big conferences are in San Francisco: OWASP Global AppSec USA and SANS in November 2026, BSidesSF and RSAC each spring.
