Cognizant Data Breach May Have Leaked Social Security Numbers

Cognizant notified customers about an April data breach that may have leaked Social Security numbers. Here’s what happened, what information was involved, and how you can protect yourself today.

What Happened in the Cognizant Data Breach?

According to Outlook Business, Cognizant — an IT services company — notified customers about a data breach that happened on April 21, 2026.

The company said personal information may have been leaked during the incident. However, it has found no evidence that the information was misused.

Outlook Business cited a Moneycontrol report about the notification. Cognizant also apologized to affected customers and advised them to contact the company with questions.

Personal information stolen in a breach can remain useful to criminals long after the incident. They may use it for phishing, identity theft, or impersonation attempts.

And Cognizant may not be the only company holding your information. Your data could already appear in another breach without you knowing.
