Microsoft Sentinel Alternative

nPro vs Microsoft Sentinel

Microsoft Sentinel is a powerful cloud-native SIEM — but it is cloud-only, priced per GB ingested, and keeps your security data in Microsoft Azure. nPro gives you self-hosted control, predictable flat pricing, and full data sovereignty.

The Ingestion Bill and the Sovereignty Question

Sentinel is deeply integrated with the Microsoft ecosystem and excellent for organisations already all-in on Azure. But two structural realities push many teams to look for an alternative. First, the per-GB ingestion-and-retention pricing means costs scale with your data — and security teams often cut logging to control the bill, creating blind spots. Second, the data lives in Azure, which is a problem for organisations under data-residency or sovereignty mandates.

nPro inverts both: a flat licence with no ingestion penalty (see our cloud vs on-premise TCO analysis), and full self-hosting so your data never leaves your infrastructure. For regulated industries and the public sector across Southeast Asia, that combination is often decisive.
