What CrowdStrike is actually selling, is someone who actually looks at the system logs and who pushes a button when something pops up. Roughly.
There are better solutions on the market. Unfortunately CrowdStrike has the more aggressive sales team.
For those wondering, I’m referring to *nix based solutions like SElinux, appArmor, iptables, nftables, cgroups, … But you need to monitor your logs if you want to take appropriate action.
