The vast majority of damages from last month’s CrowdStrike Holdings Inc.’s global IT outage will go uninsured, according to new estimates from Guy Carpenter and CyberCube Analytics Inc.

The days-long cyberincident — which grounded planes, shuttered businesses and stopped markets — cost Fortune 500 companies about $5.4 billion in damages, according to insurance company Parametrix. But insured losses are expected to be far less than that. Reinsurance broker Guy Carpenter estimated this week that insured losses will range from $300 million to $1 billion, while the risk analytics firm CyberCube puts that figure between $400 million and $1.5 billion.
