Not quite. Insurance is a product that provides compensation in the event of loss. Deploying CrowdStrike with an eye toward enterprise risk management falls under one of either changing behaviors or modifying outcomes (or perhaps both).
If the idea is "we'll hire Crowdstrike for CYA" when things like this happen, the blame is on CS and they pay with their reputation.
EDR deployment is an outcome-modifying measure, usually required as underwritten in a cybersecurity insurance policy for it to be in force. It isn't itself insurance.
