I'm confused. This is a security product for your local machine. Not the cloud.
Unless you call software auto-update "the cloud", but that's not what people usually mean. The cloud isn't about downloading files, it's about running programs and storage remotely.
I mean, if CloudStrike were running entirely on the cloud, it seems like the problem would be vastly easier to catch immediately and fix. Cloud engineers can roll back software versions a lot easier than millions of end users can figure out how to safe boot and follow a bunch of instructions.
