Financial services organisations face some of the most sophisticated cyber threats and stringent regulatory requirements of any industry. Banks, insurance companies, investment firms, payment processors, and fintech startups are high-value targets for cybercriminals seeking financial data, customer PII, and access to payment systems.
Penetration testing for financial services must address unique challenges including complex legacy systems, interconnected third-party ecosystems, real-time transaction processing, and regulatory requirements from multiple frameworks simultaneously. Financial institutions must comply with PCI DSS, SOC 2, DORA, NIST CSF, and often SWIFT CSP, requiring comprehensive testing programmes that cover web applications, APIs, mobile banking, payment gateways, and internal infrastructure.
Advanced testing such as red teaming and TIBER-EU threat-led pen testing is increasingly required by financial regulators to validate detection and response capabilities against sophisticated threat actors.
