This breach involved unauthorized access to an employee’s email account, compromising sensitive data. If you were affected, read on to learn what happened and how you can take action.

Sentry Advisors’ Data Breach Investigation

The breach was discovered on June 16, 2025, after unusual activity was detected in an employee’s email account. Sentry Advisors initiated an immediate investigation with the help of third-party forensic specialists to determine the extent of the breach. The investigation revealed that the unauthorized access took place between June 12, 2025, and June 16, 2025. Afterward, Sentry Advisors reviewed the email account’s contents to understand the data exposed and identify the affected individuals.

By October 23, 2025, Sentry Advisors had completed their review and verified the data that had been exposed. They found that sensitive personal information, including names, addresses, and phone numbers, was compromised. While the breach involved a single employee’s email account, the potential risk to individuals’ personal information was significant, prompting Sentry Advisors to notify all affected individuals and take further actions to safeguard their data.

In response to the breach, Sentry Advisors took swift actions to secure their systems, including changing account passwords and reviewing internal security policies and procedures. They also began offering affected individuals 12 months of free credit monitoring services through Cyberscout, a TransUnion company.
