The Gramm-Leach-Bliley Act (GLBA) removed regulations prohibiting mergers between banks, insurance companies, and brokerage firms. Title V of GLBA addressed privacy concerns by requiring financial institutions to implement safeguards to protect customers' personal information, disclose privacy policies, and allow customers to opt out of information sharing. The GLBA oversaw regulations for financial institutions, their service providers, and any companies receiving customer information.
