SOX Penetration Testing Providers

Sarbanes-Oxley Act · North America

The Sarbanes-Oxley Act requires publicly traded companies to maintain internal controls over financial reporting and have those controls independently audited. Section 404 specifically requires management and external auditors to assess the effectiveness of internal controls, which increasingly includes IT general controls (ITGCs) covering access management, change management, and IT operations.

Penetration testing supports SOX compliance by identifying vulnerabilities in systems that process, store, or transmit financial data, including ERP systems, financial databases, reporting platforms, and the network infrastructure that supports them.

While SOX does not explicitly require penetration testing, auditors increasingly expect evidence of security testing as part of the IT control environment. Financial institutions and publicly traded companies that demonstrate regular penetration testing and vulnerability management are better positioned during SOX audits and reduce the risk of material weaknesses related to IT controls being identified.
