Apparently it’s the next iteration of AI based antivirus where it uses smart algorithms to detect system behaviours and makes assessments on whether they’re malicious or not
I know there is a lot of marketing fluff, but yes, it is an EDR. Which means instead of just checking file signatures against a database if known bad stuff, it actually examines what applications do and makes a sort of judgement on if it is acting maliciously or not. I use a similar product. Although the false positives can sometimes be baffling, it honestly can catch a legit program misbehaving.
On top of that, everything is logged. Every file, network connection, or registry key that every process on the computer touches is logged. That means when something happens, you can see the full and complete list of actions taken by the malicious system. Thus can actually be a drain on the computer, but modern systems handle it well enough.
SentinelOne. They are more reseller/MSP friendly, but the product is very similar to CrowdStrike.
