Understanding your Interstate Commercial Glass & Door data breach notification letter
If a Interstate Commercial Glass & Door letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
Interstate Commercial Glass & Door is a construction and building services company specializing in the installation and maintenance of commercial glass and door systems. As part of their standard business operations, the company collects and maintains sensitive information related to employees, contractors, and corporate clients, including payroll records, tax documentation, and project-related financial data. In 2025, the company officially reported a data security incident to the Indiana Attorney General, confirming that unauthorized access to their systems occurred. If you have received a formal data breach notification letter from the company, it indicates that your personal information was likely stored within their systems at the time of the incident. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the protective measures being offered.
