ZonForge Sentinel vs Microsoft Sentinel
Last updated: 2026-07-03 · Vendor-authored (ZonForge); written to be factual and fair. Verify both products with trials — ZonForge has a no-signup live demo and a free plan.
Microsoft Sentinel is Microsoft's cloud-native SIEM/SOAR, running on Azure and priced primarily by data ingest. ZonForge Sentinel (no relation, despite the shared word) is an AI-native SOC platform. The difference that matters: Microsoft Sentinel equips analysts with a SIEM inside the Azure ecosystem; ZonForge Sentinel autonomously performs the Tier 1–2 investigation layer.
Comparison table
| ZonForge Sentinel | Microsoft Sentinel | |
|---|---|---|
| Category | AI-native SOC platform (autonomous alert investigation + detection + response) | Cloud-native SIEM + SOAR on Azure |
| Alert investigation | Autonomous AI investigation of every alert (Tier 1–2), with evidence trails | Human analysts using incidents/workbooks; Security Copilot assists but analysts drive |
| Deployment | SaaS only, agentless (API connectors); setup in hours | Azure resource; requires Log Analytics workspace design, connector and analytics-rule configuration |
| Pricing model | Flat plans: Free / Growth $299/mo / Scale $999/mo / Enterprise custom — not usage-metered | Per-GB ingest (pay-as-you-go or commitment tiers); Microsoft 365 E5 includes some free ingest allowances |
| Ecosystem | Cross-cloud: AWS, Azure, GCP, Okta, Google Workspace, GitHub and 35+ connectors | Deepest with Microsoft stack (Defender, Entra ID, M365); good third-party connector library |
| Query language | Guided investigation + hunt queries | KQL — powerful, requires analyst skill investment |
| Target customer | Startups, SaaS companies, SMEs, MSPs/MSSPs, lean security teams | Azure-committed enterprises, often with E5 licensing and SOC staff |
Best fit
Microsoft Sentinel fits organizations deeply committed to Azure and Microsoft 365 — especially E5 licensees whose bundled benefits change the economics — with analysts who know or will learn KQL. ZonForge Sentinel fits multi-cloud or Google-Workspace/AWS-centric teams, and any lean team that needs investigation done for them rather than a workbench to do it in.
When to choose Microsoft Sentinel
- Your identity, email, endpoints, and cloud are predominantly Microsoft — the native Defender/Entra integration is unmatched.
- You hold E5 licenses whose included ingest allowances materially cut the SIEM bill.
- Your analysts already work in KQL/Azure tooling.
- Procurement strongly prefers consolidating on the Microsoft agreement.
When to choose ZonForge Sentinel
- You're multi-cloud or Google-first — AWS/GWS/Okta telemetry is first-class in Sentinel, not an add-on connector exercise.
- Nobody on the team has KQL time: ZonForge investigates autonomously instead of handing analysts a query language.
- You want predictable flat pricing rather than per-GB ingest planning.
- You're an MSP serving clients across Microsoft AND Google ecosystems from one console.
Honest caveat: ZonForge Sentinel is not a full replacement for every enterprise use case — very large SOCs with custom data-pipeline requirements, on-premises mandates, or petabyte-scale log analytics needs may still require a traditional platform (sometimes alongside Sentinel).
Migration considerations
- Naming care: the products are unrelated — in RFPs and docs, distinguish "Microsoft Sentinel" from "ZonForge Sentinel" explicitly.
- E5 math first: compute your effective Microsoft Sentinel cost after E5 benefits before comparing bills.
- Analytics rules: inventory which Microsoft Sentinel analytics rules actually produced true positives; ZonForge's managed detections cover common cloud/identity techniques out of the box.
- Keep Defender products: ZonForge ingests Microsoft 365/Defender signals — replacing the SIEM layer doesn't mean replacing Microsoft security tooling.

Frequently asked questions
Are ZonForge Sentinel and Microsoft Sentinel related?
No. Microsoft Sentinel is Microsoft's Azure cloud SIEM. ZonForge Sentinel is an independent AI-native SOC platform by ZonForge (founded 2024). They share only the word "Sentinel."
Which is cheaper?
It depends on ingest volume and E5 licensing. Microsoft Sentinel bills per GB ingested; ZonForge uses flat plans from $0 to $999/month plus custom enterprise. High-volume environments without E5 benefits typically find flat pricing more predictable.
Can ZonForge Sentinel monitor Microsoft 365?
Yes — Microsoft 365, Entra ID (Azure AD), and Azure activity logs are supported integrations alongside AWS, GCP, Okta, and Google Workspace.
