NYDFS Cybersecurity Compliance for Self-Hosted Systems

A breach can drain your company before you even see it coming. The NYDFS Cybersecurity Regulation was built to stop that. If you self-host systems, the stakes are higher and the margin for error is smaller.

Self-hosted infrastructure gives you control, but it also makes you the primary line of defense. Under the NYDFS Cybersecurity Regulation, covered entities must maintain strong access controls, continuous monitoring, and robust incident response. It is not a checklist you pass once. It is an ongoing discipline enforced by audits, documentation, and penalties for failure.

Section 500.02 requires a documented cybersecurity program based on risk assessment. For self-hosted environments, that means mapping every asset, service, and endpoint, then locking down each point of ingress. Section 500.03 demands written policies approved by senior management. If you self-host, these policies must match the reality of your deployment — firewall configurations, patch pipelines, log retention schedules.

Continuous monitoring is explicit in Section 500.05. In cloud deployments, some of that comes baked in. In self-hosted setups, you must build it. Logging agents, SIEM integration, automated alerting, and forensic-ready storage are table stakes. Section 500.07 enforces multi-factor authentication on any remote access, including VPN and SSH.

The NYDFS Cybersecurity Regulation also requires regular vulnerability assessments (Section 500.09) and penetration testing. Self-hosted systems demand tight version control and prioritized patching to remove exposed CVEs fast. Failure to act can be considered a violation.

For incident response (Section 500.16), your plan must be more than a PDF in a shared folder. It should be tested against a live environment, with clear roles, communication channels, and escalation paths. In self-hosted contexts, restore procedures depend on solid backups isolated from production.

Compliance is not optional. NYDFS can levy fines and revoke licenses. The cost of building a secure, compliant self-hosted stack is large, but the cost of ignoring it is bigger.
