(the VMWare owned product isn't CrowdStrike, that just had the best SEO page with a clear description. VMWare have Carbon Black which is the other dominant player in this market https://www.vmware.com/uk/products/whats-new/carbon-black.ht... )
I work for CrowdStrike just so any potential bias is out there in the open, but do not speak for them.
