Never herd of CrowdStrike !
I believe another user talked about CrowdStrike in this thread, but I'd like to add a bit more of information: CrowdStrike shouldn't really be in that comparison, as their solution isn't an antivirus per se, rather, it's an
advanced threat protection solution, as they focus on
advanced persistent threat (APT). They "lie" a bit telling that their solution can replace signature based AVs, but in the end, they can't (yet). The best scenario (which is very costly) is having endpoint AV + ATP.
Their main solution is CrowdStrike Falcon, an ATP solution for enterprise endpoints. They also sell the Falcon Search Engine (previously named as Falcon MalQuery), which is a search engine for IOCs. They claim (and I believe in them) that their database is the largest out there, as they have integration with Virustotal and also have their own sensors, the search engine is very powerful. Their solutions are all clouds based, so this is a thing to consider if you have subnets in your network that are not allowed to go to Internet (they don't have the option to deploy internal cloud). They are the #2 AWS client, only losing to Netflix, so this might show you the scale we are talking about.
They also offer threat intelligence services and other things. There is a lot more to be said about them, but I believe that will give you a hint.
I know about that because I ran a POC with their ATP solution for my company, and they did a great job spotting APT techniques, but failed to spot some community malwares that any "big name" AV would spot.
