Competitive Comparison

GhostAnalyst vs Microsoft Sentinel

Microsoft Sentinel is the natural choice for Microsoft-centric environments. GhostAnalyst is vendor-agnostic, deploys on any infrastructure, and keeps your data outside US CLOUD Act jurisdiction, regardless of where Microsoft stores it. If your environment includes non-Microsoft devices or your jurisdiction requires data-residency guarantees, GhostAnalyst addresses both without compromise.
