We're testing Cylance (consumer edition) in the lab.
It's actually really slick. Fast installer. Looks great. Exceedingly lightweight. We're not finding *ANY* telemetry coming off this thing, which is surprising but the SIEM is still pointed at it for more examination. It examines every file activity on your system, even Windows system processes in some cases.
I actually like the fact it doesn't have 'extra' garbage.. I don't want URL scanners, phishing protection, password managers, system cleanup tools or any of that rubbish. Cylance paired with Heimdal should be really good as Heimdal would pick up the slack of Cylance not utilizing HTTP/HTTPS scanning technology. Since Heimdal is better than most AV HTTP/s scanners, it's a better choice IMO.
For some people, for example those with ASUS Trend AiProtection routers, Gryphon Secure Router (ESET/Zvelo), Cujo, Dojo, Norton Sphere, F-Secured Safe Router, Bit Defender box, they certainly would be totally fine running only Cylance on their Windows boxes because the URL scanning heavy lifting is on the router/UTM. Cylance might be a perfect solution for those under those conditions. It might even be enough using Chrome and Google's own site protection, along with just a malware blocking DNS.
Overall - I'm impressed with it. I was super-skeptical at first, largely because of the initial CIA seed money. However the CIA seed money amounts to peanuts now compared to the 500million+ valuation of Cylance, as evidenced by their 800 employees and giant new office. I'm emboldened by the fact you can turn off ALL file submission without risking security, and that they have seemingly decided to forego telemetry gathering and intrusive logging.
I think their newer competitor is Crowdstrike which has released their Falcon Artificially intelligent endpoint protection. However Crowdstrike, while very advanced, does not sell to consumers.
