Massachusetts Data Breach Law

Massachusetts Data Security Regulations (201 CMR 17.00) & M.G.L. c. 93H

Massachusetts has some of the nation's most rigorous data security requirements. 201 CMR 17.00 requires every company holding Massachusetts resident data to maintain a written information security program (WISP) — and failure to have one is itself a violation. Notification is required within a reasonable time and AG must be notified.

Notification Window
As soon as reasonably possible
Available Damages
Civil penalties under Ch. 93A ($25 per violation minimum, treble damages for willful violations); AG enforcement

Are You Eligible to File a Claim?

Massachusetts residents can pursue claims under Chapter 93A, which provides minimum $25 per violation — and triple damages for intentional violations. If a company lacked a proper security program, that's automatic liability.
