FAQs
How often should US-based businesses do pentesting for compliance and security purpose?
The pentesting frequency will depend on industry regulations, data sensitivity and how often your systems undergo change. For example, PCI DSS mandates annual pentesting and after any big infra or app changes you make. However, the best practices would be to test at least quarterly or adopt continuous pentesting. This ensures that vulnerabilities introduced through updates, third-party integrations or configuration drift are found.
Which U.S. regulations require pentesting for compliance?
Many U.S. regulatory frameworks either require or strongly recommend penetration testing. PCI DSS for businesses handling credit card data requires annual testing and after system changes. HIPAA for healthcare organizations recommends regular testing as part of its security rule. The CMMC (Cybersecurity Maturity Model Certification) for defense contractors mandates security assessments including pentesting for certain levels. Then, there are State-specific data protection laws such as the California Consumer Privacy Act (CCPA) which may not explicitly mandate testing but require reasonable security measures, for which pen tests are a good option.
How can U.S. companies evaluate the credibility of a pentesting vendor?
Your company should assess technical and operational credibility when selecting a penetration testing vendor. Look for pentesters with industry-recognized certifications such as OSCP, OSCE, or CISSP. Verify if the company follows recognized testing frameworks like OWASP, NIST SP 800-115 or MITRE ATT&CK. Ask for sample reports to evaluate clarity, depth and remediation guidance. Assess whether the vendor has experience in your industry and understands compliance needs relevant to your business.
What should U.S. businesses include in the scope of a penetration test to get maximum value?
U.S. businesses should focus the scope of a penetration test on assets that, if compromised, would cause the greatest operational, financial or regulatory harm. This often includes customer-facing web applications, employee access points, cloud environments, APIs and systems handling sensitive data. Prioritizing recently updated infrastructure, third-party integrations or remote access channels ensures the test reflects current risks. A tailored scope aligned with compliance needs—such as PCI DSS or HIPAA—helps translate findings into meaningful action and regulatory readiness.
