Understanding New York’s Cybersecurity Regulation: What Every Business Needs to Know


Understanding New York’s Cybersecurity Regulation: What Every Business Needs to Know

Cyber threats are no longer rare incidents; they’re daily realities for organizations of every size. Recognizing this growing risk, the New York State Department of Financial Services (DFS) implemented 23 NYCRR 500, a set of cybersecurity requirements designed to protect businesses and consumers from data breaches and operational disruptions.

This regulation, often referred to as the NYDFS Cybersecurity Regulation, outlines a framework every financial services company, and increasingly, organizations working with them, should understand and adopt.


Why the Regulation Exists

The DFS created this framework in response to the increasing number of cyberattacks targeting sensitive financial and personal data. From organized crime to state-sponsored hacking, the potential for catastrophic loss is significant.
The regulation ensures that all covered entities (banks, insurance companies, and financial institutions licensed in New York) maintain a minimum standard of cybersecurity while allowing flexibility for companies to scale their programs based on size, complexity, and risk.


Core Components of the NYDFS Cybersecurity Requirements

1. Establish a Comprehensive Cybersecurity Program

Every covered entity must maintain a program that protects the confidentiality, integrity, and availability of its information systems. This includes:

  • Identifying internal and external risks
  • Implementing protective measures
  • Detecting and responding to cybersecurity events
  • Recovering and reporting incidents

2. Develop a Written Cybersecurity Policy

Organizations must document and maintain written policies approved by senior leadership. These policies should cover everything from data governance and asset management to incident response, third-party management, and business continuity.

3. Designate a Chief Information Security Officer (CISO)

A qualified individual must oversee the cybersecurity program, enforce policy, and report annually to the board or senior management. The CISO may be internal or outsourced but remains ultimately accountable to the organization.

4. Conduct Risk Assessments and Testing

Regular risk assessments help organizations adapt to emerging threats. Companies must also conduct:

  • Annual penetration testing
  • Bi-annual vulnerability assessments
    to ensure systems are secure and controls remain effective.

5. Manage Access and Data Retention

Access to sensitive systems and nonpublic information must be limited to authorized users, with privileges reviewed regularly.
Additionally, data retention policies should ensure secure disposal of information no longer needed for business or legal purposes.

6. Implement Multi-Factor Authentication (MFA)

MFA or risk-based authentication must be used for all external network access, a key safeguard against unauthorized entry and compromised credentials.

7. Protect Data Through Encryption

Nonpublic data must be encrypted both in transit and at rest. If encryption is not feasible, equivalent compensating controls approved by the CISO must be in place and reviewed annually.

8. Create an Incident Response Plan

Companies must have a written plan outlining how they will detect, contain, and recover from cyber incidents. This includes communication protocols, documentation, and post-incident reviews.

9. Notify the Superintendent of Cybersecurity Events

Covered entities are required to report qualifying cybersecurity events to the DFS within 72 hours and submit an annual compliance certification by April 15 each year.


Exemptions and Enforcement

Small businesses (those with fewer than 10 employees, less than $5 million in annual NY revenue, or under $10 million in total assets) may qualify for limited exemptions. However, even exempt entities are encouraged to maintain strong cybersecurity practices.

The DFS has authority to enforce compliance, and violations can lead to significant penalties and reputational damage.


Why This Matters for All Businesses

Even if your organization isn’t directly regulated by DFS, many clients, vendors, and insurers now expect compliance with NYDFS-style standards as part of their due diligence process.
Building a cybersecurity program aligned with 23 NYCRR 500 demonstrates trust, accountability, and resilience, three values customers and partners increasingly demand.


Key Takeaway

Cybersecurity isn’t just an IT issue; it’s a business imperative. By following the guidance laid out in the NYDFS Cybersecurity Regulation, New York businesses can reduce risk, meet compliance requirements, and protect the people who depend on them.
