The New York Department of Financial Services (NYDFS) is a regulatory body that oversees financial products and services in New York. It was established in 2011 through the merger of the New York State Banking Department and the New York State Insurance Department. The NYDFS has a broad mandate to protect consumers, ensure the integrity of financial markets, and enforce financial laws and regulations.

One of the key areas of focus for the NYDFS is information security. In response to the increasing number and sophistication of cyber threats, the NYDFS has implemented a comprehensive set of cybersecurity regulations that apply to all financial services companies operating in New York.

NYDFS Cybersecurity Regulations

The NYDFS Cybersecurity Regulations (23 NYCRR 500) came into effect on March 1, 2017. These regulations require financial services companies to have a cybersecurity program designed to protect consumers' private data, a written policy or policies that are approved by a senior officer or the entity’s board of directors, a Chief Information Security Officer to help protect data and systems, and controls and plans in place to help ensure the safety and soundness of New York’s financial services industry.

Key Requirements

The regulations include several key requirements:

  1. Cybersecurity Program: Each company must establish and maintain a cybersecurity program designed to protect the confidentiality, integrity, and availability of its information systems.
  2. Cybersecurity Policy: Each company must implement a written cybersecurity policy that sets out the company's policies and procedures for the protection of its information systems and nonpublic information.
  3. Chief Information Security Officer (CISO): Each company must designate a qualified individual to serve as the CISO, who is responsible for overseeing and implementing the company's cybersecurity program and enforcing its cybersecurity policy.
  4. Penetration Testing and Vulnerability Assessments: Each company must conduct annual penetration testing and bi-annual vulnerability assessments of its information systems.
  5. Risk Assessment: Each company must conduct a periodic risk assessment of its information systems.
  6. Third-Party Service Provider Security Policy: Each company must implement written policies and procedures designed to ensure the security of information systems and nonpublic information that are accessible to, or held by, third-party service providers.
  7. Incident Response Plan: Each company must establish a written incident response plan designed to promptly respond to, and recover from, a cybersecurity event.

Compliance and Enforcement

Companies must certify compliance with the regulations annually. The NYDFS has the authority to enforce the regulations and can take action against companies that fail to comply, including imposing fines and other penalties.


The NYDFS Cybersecurity Regulations represent one of the most comprehensive sets of cybersecurity regulations in the United States. They reflect the growing recognition of the critical importance of cybersecurity in the financial services industry and the need for robust regulatory oversight to protect consumers and ensure the integrity of financial markets.

While the regulations impose significant obligations on financial services companies, they also provide a framework for companies to develop and implement effective cybersecurity programs. By doing so, companies can not only comply with the regulations but also better protect themselves against cyber threats, thereby enhancing their overall risk management and business resilience.
