What our shortlists say about the one we picked.
Best for: Large companies standardizing on Cortex XSIAM
Unit 42 Managed XSIAM is on the list for scope, because one service covers endpoints, cloud, network, identity and email with threat hunting and custom detection engineering. It fits mid-market and enterprise companies that are standardizing on Cortex XSIAM, since the service runs on that platform. Weigh that commitment before you sign, because leaving the service also means leaving the platform.
