Shouldn't that hit Crowdstrike's stock price much more than it has then? (so far I see ~11% down which is definitely a lot but it looks like they will survive).
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).
Pay for what exactly though? Cybersecurity incidents result in material loss, and someone somewhere needs to provide dollars for the accrued costs. Reputation can't do that, particularly when legal liability (or, hell, culpability) is involved.
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.
