Thank you for outlining your environment so clearly. This is a common challenge for very large enterprise deployments.
Hexnode addresses this through Fleet Sharding, an architecture designed for high scale UEM environments. Instead of relying on a single monolithic backend, large fleets are split into multiple autonomous regional nodes.
Each node independently handles device records, policy execution, compliance checks, and telemetry, which improves performance, limits failure impact, and aligns device data with regional compliance requirements. At the same time, administrators retain centralized visibility, license governance, and policy consistency through a master-level console.
