- SIEM combines log collection, real-time correlation, UEBA (user/entity behavior analytics), and compliance reporting into one platform
- Enterprise SIEM deployments (Splunk, QRadar) routinely run into six or seven figures annually once licensing, storage, and skilled staff are counted
- Log360 bundles log management, UEBA, and compliance reporting (HIPAA, PCI-DSS, GDPR, SOX) at a price point built for the mid-market, not the largest enterprises
What SIEM Actually Solves
Without a SIEM, a security team is managing dozens of disconnected tools, each with its own alerts and dashboards — a breach might trigger alerts across multiple systems, but nobody sees the full attack chain until it's too late. SIEM centralizes log collection from firewalls, servers, and applications, normalizes it into a common format, and correlates events across systems and time to surface the alerts that actually matter instead of drowning analysts in noise. See our full guide on what SIEM is and how it works for the underlying mechanics.
Where SIEM platforms actually differ is less about whether they can do this in principle, and more about ingestion scale, ease of deployment, and total cost — which is exactly where the market splits into enterprise-scale platforms and mid-market-focused ones.
ManageEngine Log360
Who It's For
Mid-size IT/security teams that need real SIEM capability — log management, UEBA, compliance reporting — without the multi-terabyte-per-day ingestion scale or seven-figure budget that Splunk and QRadar are built around. It's not built to compete with those platforms at the largest-enterprise end; it's built for the much larger segment of organizations below that scale who still have genuine compliance and threat-detection requirements.
How It Compares
Splunk Enterprise Security
The market leader — ingests virtually any data source, excels at correlation, and offers the most powerful visualization and search of any tool here. Used heavily by Fortune 500 companies and government agencies. Also the most expensive and operationally heaviest platform in this comparison by a wide margin.
IBM QRadar
Strong in threat intelligence integration and compliance reporting, popular in regulated industries, and handles high-volume environments well. Similar enterprise pricing and operational weight to Splunk — a fit for the same scale of organization, not a lighter-weight alternative to it.
Microsoft Sentinel
Microsoft's cloud-native SIEM, deeply integrated with Azure and Microsoft 365 — the natural default if your organization is already Microsoft-centric. Consumption-based pricing can be lower than legacy platforms at moderate scale, though costs scale with ingestion volume in a way that needs active monitoring.
ManageEngine Log360
A unified SIEM aimed squarely at mid-market IT teams who find Splunk or QRadar overkill on both price and operational complexity. Bundles log management, UEBA, and compliance reporting (HIPAA, PCI-DSS, GDPR, SOX) into one console, with pricing that's typically a fraction of the enterprise incumbents above. The tradeoff is scale — it's not built for the multi-terabyte-per-day ingestion that Splunk or QRadar handle at the largest enterprises, so it fits best for organizations needing real SIEM capability without a seven-figure line item.
Elastic Security
Built on the open-source Elastic Stack (Elasticsearch, Logstash, Kibana), with commercial support available. Growing quickly because it's more affordable and more customizable than the legacy enterprise platforms — the tradeoff is more hands-on configuration work to get the same out-of-box compliance reporting that Log360 or QRadar ship with by default.
| Tool | Best fit | Relative cost |
|---|---|---|
| Splunk Enterprise Security | Largest enterprises, maximum flexibility | Highest |
| IBM QRadar | Regulated, high-volume enterprise environments | High |
| Microsoft Sentinel | Already Azure/M365-centric | Consumption-based |
| Log360 | Mid-market, real SIEM without enterprise budget | Lower, fixed-tier |
| Elastic Security | Budget-conscious, comfortable with more setup | Lower, more DIY |
Bottom Line
- Largest-scale enterprise, need maximum ingestion and correlation flexibility, budget isn't the constraint? Splunk or QRadar.
- Already deep in the Azure/Microsoft 365 ecosystem? Sentinel keeps SIEM in the same platform.
- Mid-size team needing real SIEM — log management, UEBA, compliance reporting — without enterprise-tier pricing? Log360 is built for exactly that gap.
- Comfortable with more hands-on configuration in exchange for lower cost and full customization? Elastic Security.
