SEC Regulation S-P Compliance

What Regulation S-P Requires from Small Firms

The SEC’s 2024 amendments to Regulation S-P introduced significant new cybersecurity obligations for broker-dealers, investment advisers, investment companies, funding portals, and transfer agents. For small firms (those under $1.5B AUM), the compliance deadline is June 3, 2026.

The core requirements are:

• Written incident response program that covers how your firm detects, contains, and recovers from unauthorized access to customer information
• Customer notification within 30 days of discovering a breach involving sensitive customer information
• Service provider oversight policies requiring vendors to notify your firm within 72 hours of a breach on their systems
• Written recordkeeping for 5 years documenting your safeguards and disposal procedures
• Monitoring and logging capable of making an affirmative determination about whether data was accessed or exfiltrated in the event of an incident

SEC examiners have been clear: they are not just looking for written policies. They want to see evidence that those policies are actually implemented and enforced.

What SEC Examiners Look for

When SEC examiners arrive, they request documentation including:

• Your written incident response plan with all three required elements: assess, contain, and notify
• Vendor contracts showing negotiated cybersecurity obligations and 72-hour notification provisions
• A data flow map showing where customer non-public personal information (NPPI) lives, how it moves, and how it is decommissioned
• Evidence that monitoring and detection tools are purchased, enabled, and properly configured
• Log data sufficient to determine whether customer data was accessed following an incident
• Your IT/cybersecurity risk matrix showing identification, rating, mitigation, and iteration over time

A common finding from SEC examinations: firms purchase security tools but fail to enable key modules. Buying the tool is not sufficient. The SEC expects to verify it is actually in use.

How SIMAPTIC Closes the Gap

SIMAPTIC provides automated internal network security assessments that generate exam-ready documentation mapped to NIST 800-53 Rev 5 controls and the MITRE ATT&CK framework, industry-standard benchmarks for demonstrating the administrative, technical, and physical safeguards Reg S-P requires.

Automated Risk Identification

SIMAPTIC runs realistic attack scenarios across your internal network, identifying vulnerabilities before an examiner (or a real attacker) finds them. Every test produces a documented risk profile that forms the foundation of your cybersecurity risk matrix: exactly what the SEC expects to see evidence of.

Control Validation Before Examiners Arrive

SEC examiners don’t just read your policies. They look for artifacts proving your controls actually fired. As one SEC examiner put it at the agency’s January 2026 small firms outreach event: “It’s not just written for us. It’s written and executed in the office.” SIMAPTIC’s automated campaigns generate timestamped evidence of controls in action, giving your firm the artifacts examiners expect to see.

NIST 800-53 Mapped Reports

Every SIMAPTIC assessment generates a report mapping findings to NIST 800-53 Rev 5 controls. The result is a direct, auditable line from your security posture to the regulatory framework the SEC recognizes, with a clear remediation plan for any gaps.

Independent Validation of MSP and Vendor Controls

Many small RIAs rely on managed service providers for day-to-day IT and security operations. But the SEC’s position is clear: your firm is responsible for verifying what your vendors are doing, not just taking their word for it. SEC examiners have specifically described independent third-party validation of MSP controls as helpful during examinations. SIMAPTIC provides that independent view by running real attack scenarios against your environment regardless of who manages it, producing findings your firm can act on.

On-Demand, Repeatable Testing

SEC examiners expect to see that security is an ongoing practice, not a one-time event. SIMAPTIC assessments can be run on demand and repeated across compliance cycles, giving your firm a continuous record of security validation that demonstrates the iterative risk management the SEC looks for.

A Practical Path to Compliance for Small Firms

The SEC has acknowledged that small firms operate under real resource constraints. The good news: firms that have structured their operations carefully, limiting where customer data actually resides, can significantly reduce the scope of required controls.

SIMAPTIC is built with small firms in mind. With assessments starting at $4,000, enterprise-grade security validation is finally within reach. Each assessment produces:

For firms facing SEC examination, this means walking in with documented evidence of a working security program, not just a policy binder.
