Not just Crowdstrike
Seems rather a mess.
Crowdstrike Vs NSS Labs, more here: http://www.csoonline.com/article/3169582/techology-business/crowdstrike-attempts-to-sue-nss-labs-to-prevent-test-release-court-denies-request.html
Which has a link to a nice twitter spiel here : https://twitter.com/da_667/status/831350334912069636 relating to issues with NNS Labs in general
and a further few links relating to Cylance and it's similar issues.
Which could all be sour grapes.
Add into that mix that people are stating that AV is pretty much useless anyway (a google bod and an ex-FBI bod just recently) and you have a nice steaming pile to wade through.
