All you need to know: the Gramm-Leach-Bliley Act (GLBA)

The Gramm-Leach-Bliley Act (GLBA), also known as “the Financial Modernization Act of 1999”, stands as a cornerstone of data privacy regulation in the United States. It sets forth stringent guidelines for how financial institutions handle individuals' private information. 


Understanding GLBA's core provisions

At its core, the GLBA encompasses three crucial rules:

  • Financial Privacy Rule: This mandates the regulation of the collection and disclosure of private financial information.

  • Safeguards Rule: It requires financial institutions to implement comprehensive security programs to protect information.

  • Pretexting Provisions: These prohibit the acquisition of private information under false pretences.

The GLBA empowers consumers with rights to privacy notices and choices in information sharing. This includes a wide array of personal data ranging from financial to biometric and internet data. The act has a broad scope; affecting banks, brokerage houses, insurance firms, and even universities. 

The act places a significant emphasis on safeguarding personally identifiable information (PII) against unauthorised access. The enforcement of GLBA is carried out by various authorities such as the Federal Trade Commission (FTC), the Federal Deposit Insurance Corporation (FDIC), and the Consumer Financial Protection Bureau (CFPB).


Impact of the 2008 financial crisis and the Dodd-Frank Act

The 2008 financial crisis exposed significant vulnerabilities in the financial sector, leading to the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act in 2010. This act significantly reformed financial regulation, aiming to reduce risks in the financial system. 

One of its key outcomes was the creation of the CFPB, which plays a crucial role in enforcing consumer protection laws, including aspects related to the GLBA. The bureau's involvement has strengthened the enforcement of privacy regulations, ensuring better protection of consumer financial information.


Recent amendments and their impact

The GLBA has recently undergone significant amendments. The Safeguards Rule, in particular, was updated in 2021 to provide a more detailed framework for the security measures financial institutions must implement. These amendments, effective from June 2023, include:

  • Mandatory encryption of customer information

  • Requirement of multi-factor authentication for system access

  • Conducting periodic risk assessments to inform security programs

  • Procedures for evaluating third-party applications and secure disposal of customer information

  • Implementation of robust user activity monitoring systems

  • Regular training for personnel on security awareness

  • Development of a comprehensive incident response plan

The definition of "financial institutions" has now also been expanded under the FTC’s newer Final Rule, to include entities engaged in activities that the Federal Reserve Board deems incidental to financial activities. However, national banks and federal credit unions are exempt from the FTC’s jurisdiction.


What do you need to do to comply?

Businesses, particularly those newly classified as financial institutions, must familiarise themselves with these regulations and ensure strict adherence. Regular audits and robust data security measures are essential. IT professionals should also prioritise GLBA compliance in their data management and security strategies.

Additionally, consumers must stay informed about their rights under the GLBA. Awareness of privacy notices and exercising choices in information sharing are critical steps in safeguarding personal financial information.


The Gramm-Leach-Bliley Act is more than just a regulatory framework; it's a fundamental aspect of how financial information is protected in the digital age. With its recent updates, the GLBA continues to evolve, ensuring that financial institutions maintain the highest standards of privacy and data security. Whether you're a business or consumer, understanding and adhering to the GLBA is crucial in the landscape of financial data privacy.
