California
Fontana has no security group of its own; most activity in the Inland Empire comes from colleges (Cal State San Bernardino, UC Riverside, Riverside City College, Chaffey College) and the ISC2 SoCal Inland Empire chapter, which holds virtual monthly meetings. In Fontana itself, the IT firm Zeta Sky has run a free Inland Empire Cybersecurity Summit each October, and the SoCal Tech Forum in Rancho Cucamonga holds a Saturday breakfast talk each month that sometimes covers security.
