Penetration Testing Frequency by Compliance Framework

Framework Testing Frequency Summary

• NYDFS 23 NYCRR 500: Annual penetration testing, bi-annual vulnerability assessments. Testing must be conducted based on the entity's risk assessment.
• PCI DSS 4.0: Annual testing minimum, plus testing after any significant infrastructure or application change.
• SOC 2: Not explicitly defined; auditors expect testing within the audit period. For Type II audits covering 12 months, annual testing is the standard expectation.
• HIPAA (current): No explicit frequency specified; testing should occur as part of the periodic evaluation process and whenever the environment changes materially.
• HIPAA (proposed amendments): Annual testing expected if the amendments are enacted as drafted.
• CMMC Level 2: Not explicitly named in the standard, but NIST SP 800-171 CA-8 calls for periodic testing and testing upon significant changes.
• CMMC Level 3: More frequent testing aligned with the advanced NIST SP 800-172 control set.
• Cyber Insurance: Most carriers require annual testing evidence at renewal, with some requiring it prior to initial coverage.

Building a Testing Calendar

Organizations subject to multiple frameworks can often satisfy several requirements with a single well-scoped annual engagement. A network and application penetration test conducted in Q4 can produce documentation usable for NYDFS certification (due April 15), SOC 2 audit evidence, PCI DSS Requirement 11.4, and cyber insurance renewal, all from one engagement. Grid32 helps clients plan their testing calendar to maximize compliance coverage from each engagement.

When to Test More Frequently

Annual testing satisfies most frameworks, but more frequent testing is warranted when your environment changes significantly. Major infrastructure migrations, cloud transitions, significant application launches, mergers and acquisitions, and network redesigns all represent trigger events for additional testing. PCI DSS explicitly requires this; the others strongly imply it.

Consolidating Multi-Framework Testing

Organizations subject to several frameworks do not need a separate test for each. Because most require annual, risk-based penetration testing, one well-scoped engagement can produce evidence for all of them at once, provided the scope covers the union of what each expects. Mapping a single report to each framework's requirement is more efficient and avoids redundant engagements. Grid32 structures documentation so the same test supports NYDFS, SOC 2, PCI, and cyber insurance evidence where the scope overlaps.

Frequently Asked Questions

How often does each compliance framework require penetration testing?

PCI DSS requires testing at least annually and after significant changes. NYDFS requires annual testing for covered entities. SOC 2 does not name a frequency but auditors generally expect annual testing. CMMC and federal frameworks carry periodic expectations most organizations meet with annual testing.

Should I test more often than my framework requires?

Often yes. Test again after major infrastructure or application changes, after a security incident, before or after a merger, and when a cyber insurer requires it. High-risk industries frequently move to semi-annual or quarterly cycles.

How do I build a compliance testing calendar?

Map each framework's required cadence, align testing to your audit periods, and schedule additional tests around significant changes. A predictable annual baseline with event-driven tests keeps you continuously compliant rather than scrambling before an audit.
