**Sentry Advisors Reports Data Breach Exposing Sensitive Personal Information**
Sentry Advisors, LLC, a regulatory risk consulting firm serving financial institutions, disclosed a data breach affecting individuals in Massachusetts. The incident, reported to the Massachusetts Attorney General’s office on December 18, 2025, exposed highly sensitive personally identifiable information (PII), including names, addresses, phone numbers, and Social Security numbers.
Details surrounding the breach remain unclear—neither the cause (whether a cyberattack, unauthorized access, or another incident) nor the timeline of the exposure has been specified. It is also unknown whether individuals outside Massachusetts were impacted.
Due to the nature of the exposed data, affected individuals face elevated risks of identity theft and financial fraud. In response, Sentry Advisors is providing complimentary credit monitoring, credit reports, and credit scores for 24 months through Cyberscout, a TransUnion subsidiary specializing in fraud remediation.
Affected individuals can contact Sentry Advisors’ dedicated call center at 1-800-405-6108 (Monday–Friday, 8 a.m.–8 p.m. ET) for further assistance.
