Investigation notes
The John Buck Company is a prominent real estate development and investment firm, managing complex commercial and residential property portfolios. In the course of their business operations, the company typically collects and stores sensitive personal information, including names, Social Security numbers, financial account details, and government-issued identification for employees, tenants, and business partners.
