Decision rule

Stellar Cyber's native multi-tenant architecture and whitelabel are the structural advantage for MSSPs running heterogeneous customer fleets. Exabeam's UEBA depth wins for identity-led services; the per-user pricing model fits direct-enterprise resale less well than per-node fits MSSP.

Roadmap risk

Post-merger Exabeam carries integration execution risk on the combined catalog. Stellar Cyber's standalone position is steady; product cadence is predictable.
