Understanding your Lion Brothers data breach notification letter
If a Lion Brothers 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
Lion Brothers appears to be a professional services or manufacturing firm, likely specializing in custom embroidery, apparel branding, or textile supply chain management. As a business that manages complex client accounts and employee records, they typically collect and store sensitive information including names, addresses, Social Security numbers, and financial account details necessary for payroll and commercial transactions. This security incident was officially reported to the New Hampshire Attorney General in 2025 following the discovery of unauthorized access to their systems. If you have received a formal data breach notification letter from the company, it indicates that your personal information may have been involved in this event. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered.

Keep the letter — it is your proof of connection
