Why you received this letter
Sentry Insurance Company is an insurance provider that manages complex policyholder information and financial records. As part of their standard business operations, they collect and store sensitive personal data including Social Security numbers, policy details, financial account information, and personal identification records. In 2025, the company officially reported a data security incident to the Indiana Attorney General, confirming that unauthorized access to their systems occurred. If you have received a formal data breach notification letter from Sentry Insurance, it indicates that your personal information was likely involved in this incident. This notification is intended to inform you of the nature of the breach and provide guidance on the steps you should take to protect your identity and financial security moving forward.
What to do after the letter
Confirm the notice is genuine

Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
