A multinational employer with EU operations and US public-company exposure has to satisfy three whistleblowing regimes from a single platform: EU Directive 2019/1937, Sarbanes-Oxley Section 806, and Dodd-Frank Section 922. The engineering rule of thumb, verified against the three statutes as of April 2026, is to default every workflow to the strictest regime (the EU directive’s 7-day acknowledgement and 3-month feedback timers), then layer SOX-specific audit-committee routing and Dodd-Frank’s “anonymous via counsel” carve-out as overlays on top. Configure once to the EU baseline and the US obligations fall into place as additive routing rules, not as competing pipelines.
