Florida Data Breach Notification Law: What Your Business Must Do Within 30 Days

Under Florida Statute 501.171, businesses have up to 30 days to notify affected individuals after determining a data breach occurred — with a possible 15-day extension for good cause, bringing the outer limit to 45 days. That sounds like breathing room, but the clock effectively starts running the moment you have reason to believe a breach happened, and the steps you take in the days immediately after discovery are what determine whether your business meets that 30-day deadline in control, or misses it in chaos.

Step 1: Contain and Confirm, Right Away

The immediate priority is stopping ongoing data loss without destroying the evidence needed to understand what happened. That means isolating affected systems from the network, preserving logs rather than wiping and rebuilding immediately, and getting a factual answer — not a guess — on whether personal information was actually accessed or just potentially exposed. Florida law is specifically triggered by unauthorized access to personal information, so this determination matters legally, not just technically.

Step 2: Bring In Counsel and Forensics Early

This is the point where most South Florida SMBs first involve outside expertise, and it should happen earlier than most businesses expect. Breach counsel helps preserve attorney-client privilege over the investigation, determines whether the incident meets Florida's legal definition of a breach requiring notification, and coordinates with a forensic investigator to scope exactly what data and how many individuals were affected — a number that directly determines your notification obligations.

Step 3: Scope the Notification Requirement

Florida's law has specific thresholds that change your obligations: notify affected individuals within 30 days of determining a breach occurred (45 days with a valid extension), notify the Florida Attorney General within 30 days if 500 or more Florida residents are affected, and notify the major consumer reporting agencies if more than 1,000 individuals are notified. Getting an accurate count of affected individuals as early as possible is what lets your legal and communications teams build a notification plan against a real deadline instead of a moving target.

The 30-Day Deadline (and the 45-Day Extension)

Once containment, counsel, and scoping are done, the remaining window is spent finalizing notification content, coordinating with any required credit monitoring offer, and filing with the Attorney General if the 500-person threshold is met. Missing the 30-day deadline is not a minor technicality — Florida imposes penalties starting at $1,000 per day for the first 30 days late, escalating to $50,000 per 30-day period after that, up to a $500,000 cap.

The businesses that handle breach notification well are almost never the ones without incidents — they are the ones with a plan written before the incident happened. If your business does not have a documented, tested incident response plan that covers Florida's specific notification thresholds, that is a gap worth closing now.
