Understanding Your Letter

Why Did You Receive This Letter?

You received this letter because COGNIZANT was required by Illinois law to notify every individual whose personal information was exposed in a confirmed data breach.

This is not a mistake and not a scam. Under Illinois 815 ILCS 530/10, COGNIZANT was legally obligated to identify every affected person and mail or email them a written notice once the breach was confirmed.

The fact that you received this letter means your personal data was specifically identified as being among the records that were compromised. The letter is your official, legal notice of that fact.

Illinois Law

What Illinois Law Requires

Illinois 815 ILCS 530/10

Illinois's data breach notification statute — the law that required COGNIZANT to send you this letter.

Under Illinois law, companies that suffer a data breach affecting residents must notify each individual in writing. COGNIZANT was required to:

  • Investigate and confirm the scope of the breach
  • Notify the Illinois Attorney General's office
  • Mail or email a written notice to every affected individual
  • Describe what data was exposed and when
  • Provide guidance on protective steps

The letter you received is proof that COGNIZANT completed this legal obligation — and it also serves as documentation of your potential claim.

Your Legal Rights

What You Can Do as a Victim

Join a Class Action Lawsuit

Seek Compensation for Damages
