Sarbanes-Oxley Sections 302 and 404 require public companies to maintain effective internal control over financial reporting — and your external auditor tests the IT general controls (ITGC) underneath it. Change management is the ITGC domain where auditors sample hardest, and DNS changes to the systems in your financial reporting scope are exactly the kind of change they ask about. ZoneWatcher gives you that evidence automatically.
The applications behind your financial statements — your ERP, billing platform, payroll provider, banking integrations — are all reached through DNS. A modified CNAME can silently reroute an integration. A hijacked MX record can intercept invoices and payment instructions, the opening move in business email compromise and wire fraud. When auditors evaluate whether unauthorized changes to financially relevant systems would be detected, the DNS layer is part of the honest answer.
SOX audits reward controls that run continuously and produce their own evidence. DNS monitoring is a low-effort, high-coverage addition to your ITGC story: it runs without manual effort, its logs are complete by construction, and it demonstrates management's attention to an attack path — email interception and system redirection — that connects directly to financial reporting risk and fraud prevention.
