Fontana, CA cybersecurity events & groups

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, Cal Poly Pomona) and from the ISC2 SoCal Inland Empire Chapter, which meets monthly online. Next door in Rancho Cucamonga, the SoCal Tech Forum holds a Saturday breakfast talk each month that sometimes covers security, and Cal State San Bernardino and Cal Poly Pomona each host a free public cybersecurity event in October.

ISC2 SoCal Inland Empire Chapter

Inland Empire (based in Ontario); chapter meetings are virtual · Metro area

Monthly virtual chapter meeting, 7:00 to 8:00 p.m. Pacific on Google Meet; the October 2026 meeting was Thursday, October 22

Chartered by ISC2 in November 2024. The chapter's LinkedIn page announced the October 22, 2026 meeting (updated leadership team, plans for the next few months, a demo of the new ISC2 Hivebrite chapter portal) and a same-day post on that date said the meeting was that evening; the meeting link is sent on request or by invitation to members. The chapter's own website, isc2chaptersocalie.org, shows only a placeholder page, and the ISC2 chapter portal lists no events yet. An earlier post warned the chapter might close if its Treasurer post stayed unfilled by October; the October post introduces an updated leadership team.
