What is a Data Breach Class Action lawsuit?

A company is subjected to legal action in a lawsuit when a group collects and submits a complaint regarding the same issue. A data breach class action lawsuit collects the complaints of a group of individuals that have suffered from the same data breach.

These complaints stem from companies protecting sensitive information poorly, such as financial records, Social Security numbers, healthcare data, or login credentials.

Victims of a data breach are at risk of suffering from Identity theft, as well. This lawsuit allows a group to collect and submit a complaint, and it also forces the company to answer for their failings in cybersecurity.
