SIEMs were built for single tenants or for the cloud.
open-source SIEM tools is powerful but single-tenant by design. Running it for multiple clients means multiple deployments, multiple management planes, and no shared intelligence layer. enterprise SIEM platforms scales but requires cloud infrastructure you do not own and contracts you cannot afford.
For MSSPs and sovereign security operations, neither option is acceptable. You need per-client isolation, a shared intelligence layer, and infrastructure you control outright.
Per-client database isolation — not schema separation, not row-level filtering
Shared threat intelligence from the omniapan.ai• engine across all tenants
No cloud dependency — runs on infrastructure you own
