Banks, insurance companies, fintechs, and investment firms face overlapping compliance requirements from multiple regulators. SOC 2 is table stakes for B2B fintech. PCI DSS applies to any entity handling card data. SOX ITGC applies to publicly traded firms. In the EU, DORA imposes ICT risk management requirements on financial entities starting January 2025. State-level regulations (NY DFS Cybersecurity Regulation) add additional layers. Vendor risk management is especially critical given the interconnected nature of financial services.
