The EU's Digital Operational Resilience Act (DORA) aims to enhance cyber security, manage ICT risks, and unify digital resilience requirements in the financial sector. It impacts financial entities already under IT supervision, those not yet supervised, and ICT third-party service providers (ICT-TSPs), who face significant implementation costs. Compliance with DORA is crucial for post-quantum security standards. Achieving compliance involves a two-phase strategy: detailed process planning and best practices in project management. DORA also presents competitive opportunities for ICT-TSPs. The white paper evaluates Brexit banks and the Swiss financial sector, highlighting differing challenges and cooperation models with the EU.
