What our shortlists say about the one we picked.
Best for: Teams with a major EDR that want experts on top
Zscaler MDR is on the list because it adds experts on top of the EDR, cloud and identity products you already run, without asking you to switch. That suits teams of any size that have a major EDR in place but no one to watch it around the clock. Set up the no-code playbooks with care, because they decide which responses run on their own and which wait for your approval.
