Horizon Financial Management, LLC experienced a cybersecurity breach in late 2024 involving unauthorized access to sensitive personal data.

Horizon Financial Management, LLC’s Data Breach Investigation

Horizon Financial Management, LLC—a company involved in financial operations and data processing—has disclosed a data breach stemming from an external system hacking event. The breach was discovered on October 30, 2025, though the initial unauthorized access occurred back on December 27, 2024.

The breach involved unauthorized individuals gaining access to personal identifiers, specifically names combined with other sensitive data points. While the company has not released a total number of affected individuals, 11 residents of Maine were notified. Written notices were issued to those impacted on November 26, 2025, in accordance with state data breach notification laws.

This event marks Horizon’s second reported breach in 12 months, with a previous notification filed in June 2025. While there is no indication that the compromised data has been misused, the breach raises concerns about the company’s ongoing ability to secure sensitive information entrusted to it by consumers.

In response, Horizon has partnered with Kroll to provide affected individuals with 12 months of complimentary credit monitoring services. While these steps are helpful, victims of data breaches often suffer long-term consequences and deserve the opportunity to hold companies accountable for their failure to safeguard private information.
