California
Oakland 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 talks. The one major conference in the city is NahamCon at Prompt2Pwn at the Oakland Marriott on November 20 to 21, 2026; the area's other big conferences are in San Francisco, with BSidesSF on April 3 to 4, 2027 and RSAC on April 5 to 8, 2027.
