Penetration Testing for Compliance

Penetration testing is a controlled, authorized simulation of cyberattacks against an organization's systems, applications, and network infrastructure conducted by qualified security professionals to identify vulnerabilities that could be exploited by malicious actors. While not explicitly mandated by SOC 2, penetration testing is considered a best practice for demonstrating the effectiveness of security controls and is often expected by auditors evaluating the Security and Availability Trust Services Criteria. Penetration tests typically cover external network testing, internal network testing, web application testing, API security testing, and social engineering assessments, with findings categorized by severity from critical to informational. Organizations should conduct penetration tests at least annually and after significant infrastructure changes, with results feeding into the vulnerability management and remediation process that auditors will evaluate. The cost of penetration testing varies significantly based on scope — from $10,000–$30,000 for a focused web application test to $50,000–$150,000 for comprehensive enterprise-wide assessments — and should be factored into overall compliance program budgets.
