What our shortlists say about the one we picked.
Best for: Smaller teams wanting one light agent
It earns a place because prevention, detection and patching share one agent and one console, which means fewer products for a small team to run. It fits small and mid-sized companies first, though it scales to enterprises. Its SIEM links cover Splunk, QRadar and Sentinel, so check the fit if you use something else.
