DORA Penetration Testing Providers

Digital Operational Resilience Act · Europe

DORA is the EU regulation establishing a comprehensive framework for digital operational resilience in the financial sector. Effective from January 2025, DORA requires financial entities to implement advanced testing of ICT tools, systems, and processes. Article 26 specifically mandates threat-led penetration testing (TLPT) for significant financial entities, to be conducted at least every three years using frameworks like TIBER-EU.

DORA goes beyond traditional penetration testing requirements by mandating that testing be conducted by qualified, independent testers using threat intelligence to simulate real adversary tactics, techniques, and procedures. The regulation covers banks, insurance companies, investment firms, payment institutions, and ICT third-party service providers to the financial sector.

DORA's TLPT requirements are among the most rigorous in any regulatory framework, requiring testers to demonstrate advanced capabilities in adversary simulation, threat intelligence, and financial sector expertise. Non-compliance can result in significant penalties and regulatory action from financial supervisory authorities.
