A single expired security certificate can bring your entire NYDFS Cybersecurity Regulation compliance to a halt.

The New York Department of Financial Services (NYDFS) Cybersecurity Regulation requires covered organizations to maintain strict controls over all sensitive systems. One key control is the management and validation of security certificates. These certificates authenticate systems, encrypt data in transit, and prove compliance during audits. Without valid certificates, your endpoints and APIs become non‑compliant by default.

Under 23 NYCRR 500, regulated entities must implement a cybersecurity program capable of detecting and preventing unauthorized access. Certificates are a core part of that program. They secure communication channels, protect customer data, and form the foundation of your public key infrastructure. The regulation also demands ongoing monitoring and immediate remediation of vulnerabilities—this includes expired, misconfigured, or revoked certificates.

Best practice is automated certificate lifecycle management:

• Discover every certificate—internal and external—across your network.
• Track expiration dates and issue alerts well before renewal deadlines.
• Automate renewals and deployments to prevent downtime.
• Maintain an immutable audit log for NYDFS examiners.

Failing to manage certificates correctly risks fines, legal exposure, and reputational damage. NYDFS auditors will review your processes in detail. They will expect proof that you can identify, replace, and log every certificate event. Manual tracking with spreadsheets or static lists is prone to error and does not meet the spirit of the regulation.

Security teams should integrate certificate management into their broader compliance automation stack. This keeps systems secure, reduces human error, and ensures your organization meets the continuous monitoring requirement. With the right tools, this process can run silently in the background, reducing operational overhead while satisfying NYDFS standards.
