Start with the legal perimeter. DORA applies to the financial-entity categories listed in Article 2, including credit institutions, payment institutions, account information service providers, electronic money institutions, investment firms, crypto-asset service providers, central securities depositories, central counterparties, trading venues, trade repositories, fund managers, management companies, data reporting service providers, insurance and reinsurance undertakings, insurance intermediaries, institutions for occupational retirement provision, credit rating agencies, administrators of critical benchmarks, crowdfunding service providers, and securitisation repositories. Article 2 also lists ICT third-party service providers separately from the financial-entity categories.
Then record exclusions and boundary questions. Article 2 excludes several categories, including certain AIFMs, certain insurance and reinsurance undertakings, IORPs operating pension schemes with no more than 15 members in total, persons exempted under MiFID II Articles 2 and 3, insurance intermediaries that are microenterprises or SMEs, and post office giro institutions. It also lets Member States exclude specified CRD-exempt entities located in their territory.
