I was curious enough to buy a cylance license Been running it for several months. I like it. Very light and trouble-free, system impact, if any, is not noticeable. I can't really comment on detection, as I don't intentionally throw malware at it. I do not get false positives either. Plays nice with other security apps, but not all. It did block Panda Cloud Cleaner from running, so you might consider that a false positive, but I did not, I saw it as cylance protecting itself from getting "corrupted" by incompatible software. Not mean as a negative comment on Panda, just my observation.
