Cylance was comparable several years ago. But, as you say, Blackberry bought it. Development effectively stopped at that moment. Reported bugs were going un-triaged and the software stopped moving forwards and AV software that isn't constantly adapting becomes a security risk in itself. The two are not comparable now - CS has a lot of extra features, especially in attack monitoring and analysis.

We were Cylance customers, and we changed to Crowdstrike when our contract expired. It was the right choice at the time, as was our decision to choose Cylance before them. Turns out we have pretty crappy luck.
