Sentinel Security Life Insurance Data Breach Exposes Sensitive Policyholder Information
In April 2025, Sentinel Security Life Insurance Company, a Utah-based insurer specializing in annuity and health products for seniors, disclosed a significant data breach affecting current and former policyholders, beneficiaries, and other individuals. The company detected suspicious network activity on April 15, 2025, revealing that an unauthorized actor had accessed its systems between April 7 and April 15, 2025, potentially exfiltrating sensitive files.
The exposed data includes names, Social Security numbers, taxpayer identification numbers, financial account details, dates of birth, and medical or health insurance information. Sentinel has begun notifying affected individuals via mail, with a public notice available for those without confirmed contact information.
As part of its response, Sentinel is offering free one-year credit monitoring and identity restoration services through IDX to impacted parties. Individuals can verify eligibility by contacting the company’s assistance line. Federal protections, such as fraud alerts and credit freezes, remain available to those concerned about identity theft.
The breach comes amid financial instability for Sentinel, which was ordered by regulators in December 2024 to halt new business due to solvency concerns. The company, founded in 1948, reported $879.8 million in admitted assets and $4.96 billion in gross annuity reserves as of December 2022.
Legal firms, including Shamis & Gentile P.A., are investigating potential compensation claims for affected individuals. The incident underscores the ongoing risks of cyber threats in the financial and insurance sectors.
