What our shortlists say about the one we picked.
Best for: Security teams joining endpoint, network and identity alerts
This is the pick when you want the endpoint to be one source in a wider detection program. Its size fit is mid-market and enterprise, and it is the base for Cortex XSIAM if you later want a full SOC platform. That breadth suits a staffed SOC, so if you have one or two analysts, ask how much of it you would run.
