2026 Data Breach Notification Requirements by Regulation

2026 sees no major changes, but enforcement ramps up post-Nike/Match breaches (PKWARE). Compare:

GDPR (EU/UK)	72 hrs to DPA (Art 33); individuals if high-risk (Art 34)	DPA + affected	€10-20M or 2-4% turnover	Personal data breaches risking rights
HIPAA (US Health)	60 days to individuals; HHS if >500	Individuals + media/HHS	Up to $1.5M/year	Unsecured PHI
US State Laws	Varies (e.g., CA 45 days)	Residents + AG	CA: $1-7.5M for 10K affected	Personal info (no federal law)
