MDR does not eliminate the need for an incident response plan. Where should the handoff begin?
MDR can do more than investigate and escalate alerts. Depending on the agreement, the provider may also contain threats by isolating endpoints, disabling accounts, or taking other pre-authorized actions.
But a serious incident can involve decisions beyond those agreed actions: whether to take a critical service offline, how to preserve evidence while restoring operations, and when to involve legal, leadership, or customer communications. Someone needs to own those decisions and coordinate the wider response.
The handoff should be defined before an incident, not negotiated during one.
For teams using MDR, which response actions can your provider take without waiting for approval? What triggers involvement from your internal incident owner?
