Cognizant, a leading global professional services and technology consulting firm, formally disclosed a data security incident to the Illinois Attorney General's office on April 1, 2026. The company reported that unauthorized access occurred within its systems, initiating an investigation into the event.

Due to the nature of its business, Cognizant processes and stores a significant volume of sensitive employee and client data. While the specific categories of information involved in this incident were not detailed in the public record, the filing confirms that personal information may have been exposed as a result of the unauthorized activity.

Individuals who have received an official data breach notification letter from Cognizant are encouraged to carefully examine its contents. This letter typically provides specific information regarding the scope of the exposure and outlines any protective measures or identity monitoring services the company is offering.

In the wake of such an event, it is prudent to exercise increased caution regarding personal data security.

These general precautions are widely recommended to help mitigate potential risks.

This information is based on the official filing submitted to state regulators, providing a public record for individuals to verify their notifications and understand the reported circumstances of the breach.
