WERE YOU AFFECTED?

Data Breach Lawsuits & Investigations

Every year, hundreds of millions of people are affected by data breaches that can leave them vulnerable to identity theft, credit damage, reputational harm and more.

Class action lawsuits remain one of the strongest ways to hold companies accountable for leaving consumers’, employees’ and patients’ private information unprotected. Indeed, some have resulted in multi-million-dollar settlements on behalf of those who – through no fault of their own – had their information stolen and, in the worst cases, even published on the dark web.

When a data breach lawsuit is successful, it can also require the company at fault to implement new security protocols to ensure the information it is entrusted with – medical, financial and otherwise – stays safe.
