CISO Requirements: In-House vs Virtual

Understanding the NY DFS CISO requirement and whether a virtual CISO is right for your organization.

Section 500.04 of NY DFS 23 NYCRR 500 (now titled Cybersecurity Governance) requires covered entities to designate a CISO: a qualified individual responsible for overseeing and implementing the cybersecurity program and enforcing the cybersecurity policy. For many small businesses, hiring a full-time CISO isn't practical—but there are alternatives.

Limited Exemption Note

If your organization qualifies for the limited exemption under Section 500.19(a), you are exempt from all of 500.4, including the CISO requirement. You should still designate someone responsible for your cybersecurity program: without a CISO, the senior officer responsible for the program co-signs your annual certification or acknowledgment with your highest-ranking executive.

What Does Section 500.04 Require?

The CISO must:

  • Be qualified to oversee and implement the cybersecurity program
  • Report in writing at least annually to the senior governing body (such as the board) on the cybersecurity program
  • Cover, as applicable: confidentiality of nonpublic information and integrity and security of systems; policies and procedures; material cybersecurity risks; overall program effectiveness; material cybersecurity events; and plans for remediating material inadequacies
  • Report timely to the senior governing body or senior officers on material cybersecurity issues, such as significant events or program changes
  • Co-sign the annual certification or acknowledgment with your highest-ranking executive (500.17(b))

Section 500.4(d) also requires the senior governing body to oversee cybersecurity risk management: understanding cybersecurity matters well enough (advisors are allowed), requiring management to run the program, regularly reviewing management reports, and confirming resources are sufficient.

Option 1: In-House CISO

Hiring a full-time CISO provides dedicated security leadership but comes with significant costs.

Advantages

  • • Full-time dedicated attention
  • • Deep knowledge of your systems
  • • Immediate availability for incidents
  • • Direct integration with your team

Challenges

  • • High cost ($150K-$300K+ salary)
  • • Difficult to recruit qualified candidates
  • • May be underutilized in smaller organizations
  • • Single point of failure

Option 2: Virtual CISO (vCISO)

Section 500.04(a) says the CISO "may be employed by the covered entity, one of its affiliates or a third-party service provider." This opens the door to virtual CISO arrangements. If you use one, you must retain responsibility for compliance, designate a senior member of your staff to direct and oversee the provider, and require the provider to maintain a cybersecurity program that protects you in line with Part 500.

Advantages

  • • Fraction of the cost of full-time
  • • Access to experienced professionals
  • • Breadth of experience across industries
  • • Scalable based on your needs
  • • No recruitment or retention challenges

Considerations

  • • Not full-time on-site presence
  • • Shared attention with other clients
  • • Need clear communication protocols
  • • Must ensure proper access and authority

vCISO Requirements for DFS Compliance

For a vCISO arrangement to satisfy Section 500.04, ensure:

  • Qualified Individual: The vCISO should have relevant certifications (CISSP, CISM, etc.) and experience
  • Governing Body Access: The vCISO must be able to report directly to your senior governing body
  • Documented Arrangement: Have a written agreement defining the vCISO's responsibilities and requiring the provider to maintain a cybersecurity program that protects you
  • Internal Oversight: Designate a senior member of your staff to direct and oversee the vCISO; your company keeps responsibility for compliance
  • Adequate Time: Ensure sufficient hours are allocated for your organization's needs
  • System Access: The vCISO should have appropriate access to assess your security posture

What Should Your CISO Do?

Regardless of whether you have an in-house or virtual CISO, they should:

  1. Develop and maintain your cybersecurity policies
  2. Oversee the cybersecurity program implementation
  3. Conduct or coordinate risk assessments
  4. Manage incident response
  5. Coordinate vulnerability management and penetration testing
  6. Ensure adequate cybersecurity training
  7. Report in writing to the senior governing body at least annually
  8. Co-sign the annual certification or acknowledgment
