Why you received this letter
Marquis Software Solutions appears to be a technology company specializing in enterprise software development and digital infrastructure services. In the course of providing these services, such firms typically collect and store sensitive information including client contact details, system access credentials, proprietary business data, and potentially personal information related to end-users or employees. This data breach was officially reported to the Illinois Attorney General in 2025, confirming that unauthorized access to their systems occurred. If you received a data breach notification letter from the company, it indicates that your personal information may have been included among the files accessed during this incident. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity protection services being offered.
