Data Security & Breach Notification

California data breach notification law

CA Breach Notification

California · Varies by state

Requires "reasonable security procedures and practices" for any business owning/licensing CA residents' personal information. SB 446 (effective Jan 1, 2026) added California's first hard breach-notification deadlines: 30 calendar days to notify affected consumers, plus a new 15-day AG notice deadline (for breaches affecting 500+ residents) and a processor-to-owner notice duty. Applies regardless of company size whenever you hold covered personal information about a resident of this state.
