The European Supervisory Authorities (the European Banking Authority, the European Insurance and Occupational Pensions Authority and the European Securities and Markets Authority) published a guide explaining how they will oversee critical Information and communication technology (ICT) third party service providers (CTPPs) under the Digital Operational Resilience Act (DORA). The document is intended to give external stakeholders a practical overview of the CTPP Oversight framework and support preparation for its implementation. The guide outlines the governance structure, founding principles, and oversight processes, including how Joint Examination Teams (JET) will be used, and describes the tools available to overseers. It is explicitly non-binding and does not replace legal requirements in applicable European Union law. The ESAs invite the public, financial entities and third-party providers to use the guide to prepare for oversight implementation and refer to a separate presentation for further information on implementing the DORA Oversight framework.
