DORA Article 19 incident reporting interacts with NIS2 Article 23 in ways that surprise financial entities. Both regulations require incident reporting on similar timelines (24h, 72h, longer-form). For purely financial incidents, DORA reporting takes precedence. For incidents affecting non-financial subsidiaries or non-DORA scope, NIS2 reporting may apply. The complexity: many incidents have mixed scope. A cyber attack affecting both the bank's core operations (DORA scope) and a non-financial subsidiary's operations (NIS2 scope) triggers both reporting regimes. Mature financial entities have integrated incident command structures that produce coordinated notifications: - Single incident commander - Coordinated content across DORA and NIS2 notifications - Single timeline for both reporting streams - Documented reconciliation of any differences Immature entities run parallel notification streams, often producing inconsistent information that creates supervisory follow-up complications. -> Integrate incident command. Don't run parallel streams.
