When a company gets breached, the legal fallout rarely stops at regulatory fines. More often than not, a class action lawsuit follows, sometimes within days of a public disclosure.
For affected consumers, these lawsuits represent one of the few practical ways to seek accountability. For companies, they represent a growing and costly legal exposure. Here is how the landscape has shifted, and what the current trends look like.
Class Action Filings After Data Breaches Have Increased Sharply.
Data breach litigation has grown significantly over the past decade. As breaches become more frequent and more damaging, plaintiff attorneys have become faster and more organized in their response.
According to the Identity Theft Resource Center, there were 3,205 reported data compromises in the U.S. in 2023, a 72% increase over the previous record. Each one is a potential trigger for litigation.
Courts have seen a corresponding rise in breach-related class action filings, particularly in states with strong consumer protection statutes like California, Illinois, and New York.
Standing Has Been The Biggest Legal Hurdle For Plaintiffs.
For years, one question dominated breach litigation: Can you sue if you have not suffered actual financial harm yet?
The U.S. Supreme Court’s decision in TransUnion LLC v. Ramirez (2021) tightened the requirements for standing in federal court, making it harder for plaintiffs to proceed based on risk of future harm alone.
However, state courts have been more receptive. Many plaintiffs now file in state court specifically to sidestep the stricter federal standing threshold. This shift has kept class action litigation alive and active, just redistributed across different court systems.
Settlements In Breach Class Actions Have Reached Record Highs.
The financial stakes have never been higher. A few landmark settlements illustrate the trend: Cybersecurity &
| Company | Year | Settlement Amount |
| T-Mobile | 2023 | $350 million |
| Equifax | 2019 | $575 million (FTC-led) |
| Yahoo | 2020 | $117.5 million |
| Capital One | 2022 | $190 million |
These are not outliers. IBM’s 2023 Cost of a Data Breach Report put the average total cost of a U.S. breach at $9.48 million, the highest globally, with litigation costs factored in as a significant driver.
Illinois BIPA Cases Have Reshaped Biometric Data Litigation.
One of the most consequential legal trends in recent years involves biometric data.
Illinois’ Biometric Information Privacy Act (BIPA) allows individuals to sue companies for collecting or mishandling biometric identifiers, such as fingerprints, facial scans, and voiceprints, without proper consent.
BIPA has generated a wave of class actions against employers, retailers, and tech companies. In 2023, Meta settled a BIPA-related class action for $725 million, one of the largest privacy settlements in U.S. history.
Other states are now moving to pass similar legislation, which means this category of litigation is only going to expand.
What Plaintiffs Typically Seek In Breach Class Actions.
Most breach class actions pursue a combination of the following:
- Compensation for out-of-pocket losses like fraudulent charges or credit monitoring costs.
- Statutory damages, where allowed by law (BIPA, for example, allows $1,000–$5,000 per violation).
- Injunctive relief requiring the company to improve its security practices.
- Attorney fees, which are often the primary driver of settlement size.
Companies With Weak Security Practices Face The Greatest Legal Exposure.
Courts and juries have shown little patience for companies that suffered breaches due to known, preventable vulnerabilities.
Failure to encrypt data, ignoring prior security warnings, or delaying patches, these facts surface in discovery and tend to strengthen plaintiffs’ cases considerably.
The legal trend is clear: data security is no longer just an IT issue. It is a direct liability question, and class action litigation has made that undeniable.
