Understanding your The Arc of Southern Maryland data breach notification letter

Why you received this letter
The Arc of Southern Maryland is a non-profit organization that provides comprehensive support services and advocacy for individuals with intellectual and developmental disabilities. Given the nature of their operations, they typically collect and store sensitive personal information, including health records, disability-related diagnosis information, and government identification numbers required for program eligibility and billing. In 2025, the organization officially reported a data security incident to the Maryland Attorney General, confirming that unauthorized parties may have accessed their systems. If you have received a formal data breach notification letter from the organization, it indicates that your personal or health-related information was likely involved in this incident. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered.
