RSM US LLP appears to be a professional services firm specializing in audit, tax, and consulting services for businesses. In the course of providing these services, the firm typically collects and stores sensitive personal and financial data, including client details, employee information, and proprietary financial records. In 2025, the organization officially reported a security incident to the Massachusetts Attorney General. Affected individuals have since received a data breach notification letter detailing the event. If you received one of these letters, it indicates that your personal information may have been involved in the incident.
