SOC 2 Penetration Testing Requirements

SOC 2 is the de facto standard for proving that your organization handles customer data responsibly. While the framework does not prescribe specific security tools, auditors consistently expect penetration testing as evidence that your controls work in practice, not just on paper.

This guide breaks down how penetration testing fits into the SOC 2 Trust Services Criteria, the differences between Type I and Type II audits, and what your auditor will look for in a pentest report.

What SOC 2 Requires for Security Testing

SOC 2 is built around five Trust Services Criteria (TSC) defined by the AICPA. Penetration testing directly supports several of these criteria by providing independent verification that your security controls actually prevent unauthorized access and data exposure.

Security (CC6/CC7)

Controls that protect against unauthorized access. Pentesting validates that firewalls, access controls, and authentication mechanisms function correctly.

Availability (A1)

Controls ensuring systems remain operational. Pentesting identifies denial-of-service risks and infrastructure weaknesses that could cause downtime.

Confidentiality (C1)

Controls that restrict access to sensitive data. Pentesting checks for data exposure through insecure APIs, misconfigured storage, and broken authorization.

Risk Assessment (CC3)

Processes for identifying and evaluating threats. A penetration test provides concrete evidence that your risk assessment covers real-world attack scenarios.

Auditors reviewing your SOC 2 controls want to see that you test your own defenses. Vulnerability scans alone are not sufficient. A manual penetration test demonstrates that a skilled tester attempted to bypass your controls and documents what they found. This is the strongest evidence you can provide for control effectiveness.

Type I vs Type II: When Pentesting Matters Most

SOC 2 audits come in two forms, and each has different implications for penetration testing:

Type I (Point-in-Time)

Evaluates control design at a single date
Often used as a first step toward Type II
One pentest report covering your current state is typically sufficient
Faster to achieve, but less trusted by enterprise buyers
Good starting point for startups pursuing their first SOC 2

Type II (Over a Period)

Evaluates control effectiveness over 6 to 12 months
Requires evidence of ongoing security practices
Annual pentesting (or more frequent) is expected
Remediation evidence strengthens your report
Required by most enterprise procurement teams

For Type II audits, a single pentest is rarely enough. Auditors want to see that you test regularly and that you act on the findings. Showing a pentest report alongside evidence of remediation (retesting, patched vulnerabilities, updated configurations) is what separates a clean audit from one with exceptions noted.

How Budget Security Helps You Pass Your SOC 2 Audit

Budget Security delivers penetration testing built for organizations going through SOC 2 audits. You can scope your engagement, get a quote, and schedule testing through our online platform. Pricing starts at €849 per day.

Scope your test online

Use our platform to define what needs testing: web applications, APIs, cloud infrastructure, or internal networks. Our scoping tool helps you cover the systems that map to your SOC 2 Trust Services Criteria.

Certified testers, manual methodology

Every engagement is performed by OSCP and OSWE certified penetration testers. We follow OWASP, PTES, and NIST SP 800-115 methodologies to ensure thorough coverage.

Audit-ready reports with TSC mapping

Our reports include an executive summary, detailed technical findings with CVSS scores, exploitation evidence, and clear remediation steps. Each finding references the relevant SOC 2 control criteria so your auditor can trace it directly.

Remediation verification included

After you fix the reported issues, we retest to confirm the vulnerabilities are resolved. This gives your auditor documented proof that findings were addressed, which is critical for Type II engagements.

SOC 2 Penetration Testing FAQ

What is SOC 2?

SOC 2 (System and Organization Controls 2) is an auditing framework developed by the AICPA (American Institute of Certified Public Accountants). It evaluates how organizations manage customer data based on five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy.

Is penetration testing required for SOC 2?

SOC 2 does not explicitly mandate penetration testing. However, auditors expect evidence that you proactively identify and address security vulnerabilities. A penetration test is the most effective way to demonstrate this, and most auditors will flag its absence as a gap in your security controls.

How often should you perform a pentest for SOC 2?

Most organizations conduct penetration tests annually to align with the SOC 2 audit cycle. If your environment changes significantly (new infrastructure, major application releases, or acquisitions), additional testing is recommended before the next audit period.

What is the difference between SOC 2 Type I and Type II?

Type I evaluates whether your security controls are properly designed at a specific point in time. Type II examines whether those controls operate effectively over a period, typically 6 to 12 months. Type II is considered more rigorous because it requires sustained evidence of control effectiveness.

How much does a SOC 2 penetration test cost?

A SOC 2 penetration test with Budget Security starts at €849 per day. Total cost depends on the number of applications, APIs, and network segments in scope. You can get a detailed estimate through our online cost calculator.

What should a SOC 2 pentest report contain?

A SOC 2 pentest report should include the scope and methodology, a list of all findings with CVSS severity scores, proof-of-concept evidence, business impact analysis, and prioritized remediation guidance. The report must clearly map findings to the relevant Trust Services Criteria so your auditor can verify control effectiveness.
