Introduction: Does Gramm–Leach–Bliley Act (GLBA) Apply to Your Business?
If your company collects, stores, or shares consumer financial data, there’s a good chance the Gramm–Leach–Bliley Act (GLBA) applies to you. But here’s the catch: many businesses outside of traditional banks—like fintech apps, insurance providers, and mortgage tech platforms—don’t realize they fall under GLBA oversight.
GLBA’s Safeguards Rule and Privacy Rule mandate strong consumer protections, including limits on data sharing and strict information security requirements. The challenge? Much of today’s financial data collection happens client-side through web apps, customer portals, and digital onboarding flows. Third-party scripts, tracking pixels, and tag managers often operate invisibly, creating compliance blind spots.
That’s where Feroot comes in. Unlike PCI DSS and HIPAA, Gramm–Leach–Bliley Act (GLBA) compliance isn’t just about regulated sectors—it’s about every digital touchpoint where financial data moves. Feroot gives financial institutions visibility, control, and assurance across the client-side, ensuring GLBA compliance in a modern web environment.
What Is the Gramm–Leach–Bliley Act (GLBA)?
The Gramm–Leach–Bliley Act of 1999 is a U.S. law overseen by the Federal Trade Commission (FTC) and various financial regulators. It was designed to protect consumers’ personal financial information.
Gramm–Leach–Bliley Act (GLBA) applies to:
- Banks and credit unions
- Mortgage brokers and lenders
- Insurance providers
- Fintech apps and payment providers
- Any business offering consumer financial products or services
Gramm–Leach–Bliley Act (GLBA) includes three main components:
- Privacy Rule – Requires institutions to provide clear notices on how they share customer data and gives consumers the right to opt-out of certain sharing.
- Safeguards Rule – Requires financial institutions to maintain a comprehensive information security program.
- Pretexting Provisions – Prohibits the practice of accessing private financial information under false pretenses.

Key Compliance Requirements Under Gramm–Leach–Bliley Act (GLBA)
To comply with Gramm–Leach–Bliley Act (GLBA), organizations must:
- Protect consumer financial data with appropriate administrative, technical, and physical safeguards (Safeguards Rule).
- Provide annual privacy notices explaining information-sharing practices (Privacy Rule, 16 CFR Part 313).
- Allow consumers to opt out of nonessential third-party data sharing.
- Assess and monitor risks associated with customer information systems.
- Oversee service providers to ensure they also maintain GLBA-level protections.
- Document and regularly update the information security program.
Common Gramm–Leach–Bliley Act (GLBA) Compliance Failures
Despite GLBA being law for over 20 years, compliance failures remain common:
- Hidden third-party tracking: Financial websites frequently load scripts from analytics platforms, social media pixels, and advertising networks that access consumer financial data.
- Weak vendor oversight: Institutions often fail to assess how third-party scripts and service providers handle data on client-facing apps.
- Inadequate safeguards for portals: Customer login pages, loan application forms, and online banking dashboards are prime targets for client-side attacks like Magecart-style skimming.
- Real-world consequences: In 2022, the FTC fined financial institutions for failing to implement adequate safeguards under the updated GLBA Safeguards Rule, which explicitly requires risk assessments and security monitoring.
