Financial institutions handle some of the most sensitive personal data there is, which makes data protection a regulatory requirement rather than a best practice. In the United States, this responsibility is governed by the Gramm-Leach-Bliley Act (GLBA), a federal law designed to protect consumers’ nonpublic financial information.
GLBA compliance sets clear expectations for how this data must be collected, stored, and safeguarded. Understanding GLBA compliance is important for organizations that operate in or support the financial sector. In this guide, we’ll explain what GLBA compliance means, who it applies to, what data it protects, and how enforcement works.
What is GLBA Compliance?
GLBA compliance refers to an organization’s obligation to follow the requirements set out in the Gramm-Leach-Bliley Act to secure consumers’ nonpublic personal financial information. It involves implementing policies, procedures, and safeguards that control how financial data is collected, used, shared, and secured throughout its lifecycle.
In practice, GLBA compliance focuses on reducing the risk of unauthorized access, disclosure, or misuse of financial information. Covered businesses are expected to assess potential risks to customer data, apply appropriate administrative, technical, and physical safeguards, and regularly review and update those protections.
What is the Gramm-Leach-Bliley Act (GLBA)?
The Gramm-Leach-Bliley Act (or GLBA) is a U.S. federal law enacted to safeguard consumers’ nonpublic personal financial information held by financial institutions. It establishes legal requirements for how covered organizations must handle, safeguard, and disclose customer financial data.
GLBA applies to the collection and use of financial information obtained through providing financial products or services. The law does not prescribe a single security standard but instead requires organizations to implement reasonable safeguards based on their size, complexity, and the nature of the data they handle.
Who enforces GLBA?
GLBA is enforced by multiple U.S. regulatory authorities, depending on the type of financial institution involved. The Federal Trade Commission (FTC) oversees GLBA compliance for many non-bank financial institutions, while federal banking regulators enforce the law for banks, credit unions, and similar entities under their supervision.
In addition to federal oversight, state regulators may also play a role in enforcement for certain institutions. These authorities have the power to investigate compliance failures, require corrective actions, and impose penalties when businesses have failed to meet GLBA requirements.
Who must comply with GLBA?
GLBA compliance requirements vary across organizations involved in delivering and supporting financial services:
Financial institutions
Banks, credit unions, mortgage lenders, investment firms, and insurance companies are directly subject to GLBA. These businesses routinely collect and manage sensitive financial information and are therefore required to implement safeguards that protect customer data throughout its lifecycle.
Fintech and digital financial service providers
Financial technology companies that offer services such as payment processing, lending, investment platforms, or digital financial tools may also fall under GLBA. If a company provides financial products or services and accesses consumers’ nonpublic financial information, it may be considered a covered entity under the law.
Third-party service providers
Vendors and service providers that access, process, or store financial customer data on behalf of covered financial institutions are also subject to GLBA-related obligations. While they may not be directly regulated in the same way, they are typically required to maintain appropriate safeguards and support compliance through contractual and operational controls.
What data does GLBA protect?
GLBA protects nonpublic personal information (NPI) collected by covered organizations in connection with providing financial products or services. NPI refers to personally identifiable financial information not publicly available and provided by a consumer to obtain a financial service.
This can include account numbers, transaction details, income data, credit history, Social Security numbers, and any other data derived from a consumer’s relationship with a financial institution. GLBA also covers information obtained from third parties when it is used to deliver financial services to a consumer.
GLBA does not apply to information lawfully made public, such as data from government records or widely available public sources. The law focuses specifically on safeguarding sensitive financial information that could cause harm if improperly accessed, disclosed, or misused.
Definition of Non-Public Personal Information (NPI) Under GLBA
Non-Public Personal Information (NPI) is a critical concept under the Gramm-Leach-Bliley Act (GLBA), referring to personally identifiable financial information that is not publicly available and is collected or maintained by financial institutions. NPI encompasses information that:
- Is provided by a consumer to a financial institution to obtain or apply for a financial product or service, such as a loan, credit card, or bank account.
- Results from a transaction between the consumer and the institution involving a financial product or service, including deposits, withdrawals, or loan repayments.
- Is otherwise obtained by the institution in connection with offering or providing a financial product or service, including ongoing account management or customer support interactions.
In addition, NPI also includes aggregated or derived information, such as lists, classifications, or groupings of consumers created using non-public personal data, even if combined with publicly available information.
What NPI Does Not Include
Information is not considered NPI if a financial institution or covered entity has a reasonable basis to believe that it is lawfully publicly available. To make this determination, the entity must assess:
- Whether the information is generally accessible to the public through legal means, such as public records or directories.
- Whether the individual has the ability to prevent the information from being made public and has not exercised that option.
Common Examples of Non-Public Personal Information
NPI typically includes sensitive information that could be used to identify or exploit a consumer if exposed. Common examples include:
- Personal Identifiers: Names, phone numbers, home or email addresses
- Government Identifiers: Social Security numbers, tax ID numbers
- Financial Information: Credit histories, income records, account numbers, loan balances
- Transaction Data: Details about account activity, payment history, or purchases
Effectively, NPI represents the information a consumer entrusts to a financial institution, which requires robust safeguards to protect privacy, prevent identity theft, and comply with GLBA regulations.
What are the three sections of GLBA?
GLBA is built around three core sections, rules, or provisions that define how financial institutions must handle consumers’ nonpublic personal financial information:
The Financial Privacy Rule
The Financial Privacy Rule governs how financial institutions collect, use, and share consumers’ nonpublic personal information. It requires organizations to provide clear privacy notices explaining their information-sharing practices and to give consumers the right to limit certain disclosures of their data to non-affiliated third parties.
The Safeguards Rule
The Safeguards Rule requires covered businesses to develop, implement, and maintain a written information security program to safeguard customer data. Appropriate administrative, technical, and physical safeguards must be applied based on the organization’s size, complexity, and data sensitivity.
The Pretexting Rule
The Pretexting Rule focuses on preventing unauthorized access to customer information through false pretenses or deception. It is designed to protect consumers from social engineering tactics, such as impersonation or misrepresentation, used to obtain financial data without authorization.
Requirements for GLBA compliance
GLBA compliance centers on several core obligations. These include:
- Designating responsibility for data security: Organizations must assign responsibility for developing, implementing, and overseeing the information security program, and hold those individuals accountable for maintaining safeguards.
- Conducting risk assessments: Covered businesses are expected to identify and assess risks to customer information across their systems, processes, and service providers. Risk assessments should inform the selection and prioritization of safeguards.
- Implementing appropriate safeguards: Organizations must apply administrative, technical, and physical safeguards that address identified risks. Safeguards should be proportionate to the organization’s size, complexity, and the nature of the data it handles.
- Overseeing service providers: When third-party service providers access or process customer information, businesses must take reasonable steps, including ongoing oversight, to confirm they maintain appropriate safeguards.
- Monitoring, testing, and updating safeguards: Information security programs must be monitored and tested regularly to confirm their effectiveness. Safeguards should be updated as business practices, technologies, and threats evolve.

Common GLBA compliance challenges
While GLBA requirements are clearly defined, organizations often face unique challenges:
Managing third-party risk
Many businesses rely on vendors and service providers that access or process customer financial information. Ensuring those third parties maintain appropriate safeguards, and continuously monitoring their compliance, is a common challenge.
Securing distributed and remote operations
Remote work, cloud services, and decentralized systems can increase exposure to unauthorized access if controls are not applied consistently. Managing secure access across locations and devices requires ongoing oversight.
Limited visibility into data flows
Organizations may lack a complete understanding of where customer information is stored, how it moves between systems, or who has access to it. That makes risk assessment and safeguard implementation more difficult.
Keeping safeguards up to date
Technology, business processes, and the threat landscape continues to change over time. Safeguards that were once effective may become outdated if security programs are not regularly reviewed and updated.
Resource and expertise constraints
Smaller organizations, in particular, may face challenges due to limited staffing, budgets, or security expertise. Meeting GLBA requirements still requires structured processes, even when resources are constrained.
Penalties for non-compliance with GLBA
Failure to comply with GLBA can lead to these consequences:
Regulatory enforcement actions
Regulators may investigate organizations that fail to meet GLBA requirements and take enforcement action when violations are identified. These actions can require businesses to address security gaps, revise policies, or implement corrective measures to bring their data protection practices into compliance.
Civil penalties and legal liability
Non-compliance may result in civil penalties and legal exposure, particularly when failures lead to unauthorized access or misuse of consumer data. Organizations may face monetary penalties imposed by regulators, as well as potential legal claims depending on the nature and impact of the violation.
Reputational and operational impact
GLBA violations can also damage a company’s reputation and disrupt day-to-day operations. Consequences such as loss of customer trust, increased regulatory scrutiny, and the cost of remediation efforts can create long-term business and compliance challenges beyond formal penalties.
Benefits of GLBA compliance
Organizations that comply with GLBA may experience various benefits:
- Clearer data handling standards: GLBA compliance formalizes how customer financial information is collected, accessed, stored, and shared. Defined safeguards and responsibilities reduce ambiguity in data handling practices across an organization’s teams and systems.
- Greater customer trust: Consistent adherence to GLBA requirements signals accountability in managing nonpublic personal financial information. Transparent data protection practices can strengthen customer confidence with regards to how financial data is handled.
- Lower regulatory and legal exposure: Businesses that maintain GLBA compliance face fewer regulatory findings related to data protection failures. Documented safeguards and oversight processes also support more efficient responses to audits and regulatory reviews.
- Stronger oversight of third parties: GLBA compliance places explicit expectations on how vendors and service providers handle customer data. Defined oversight requirements improve visibility into third-party practices and reinforce consistent security standards across external relationships.
