Gramm-Leach-Bliley Act: Definition & Example
Also called: GLBA

What Is the Gramm-Leach-Bliley Act?
The Gramm-Leach-Bliley Act (GLBA) is a 1999 federal law that requires financial institutions to explain how they share customers’ nonpublic personal information and to safeguard that information.
What does Gramm-Leach-Bliley Act mean?
GLBA has three main parts relevant to privacy: the Financial Privacy Rule, which requires privacy notices and, in many cases, a chance to opt out of sharing with unaffiliated third parties; the Safeguards Rule, which requires a written information security program; and pretexting provisions that prohibit obtaining customer information under false pretenses.
"Financial institution" is defined broadly and can include lenders, mortgage brokers, tax preparers, some data aggregators, and other companies significantly engaged in financial activities.
The FTC’s updated Safeguards Rule requires covered companies to designate a qualified individual to run the security program, perform risk assessments, use encryption and multi-factor authentication, and report certain security events.
Gramm-Leach-Bliley Act example
A small mortgage broker keeps borrower tax returns and bank statements. To comply with the GLBA Safeguards Rule, the broker names a security lead, encrypts stored files, requires multi-factor authentication for staff, and sends borrowers a privacy notice explaining how their information is shared.
