(15)As evidenced by the experience of the implementation of the TIBER-EU framework, holding in-person or virtual meetings including all stakeholders concerned (financial entities, authorities, testers and threat intelligence providers) is the most efficient way to ensure the appropriate conduct of the testing. In-person and virtual meetings should therefore be held at various steps of the process, and in particular during the preparation phase at the launch of the TLPT and to finalise on its scope, during the testing phase, to finalise the threat intelligence report and the red team test plan and for the weekly updates, and during the closure phase for replaying testers and blue team actions, purple teaming and to exchange feedback on the TLPT.
