Recital 103 — essential entities notifying service recipients threats

Where applicable, essential and important entities should communicate, without undue delay, to their service recipients any measures or remedies that they can take to mitigate the resulting risks from a significant cyber threat. Those entities should, where appropriate and in particular where the significant cyber threat is likely to materialise, also inform their service recipients of the threat itself. The requirement to inform those recipients of significant cyber threats should be met on a best efforts basis but should not discharge those entities from the obligation to take, at their own expense, appropriate and immediate measures to prevent or remedy any such threats and restore the normal security level of the service. The provision of such information about significant cyber threats to the service recipients should be free of charge and drafted in easily comprehensible language.
