Wazuh is a capable open-source security platform, and for teams with the engineering time to run it, it can be excellent value. But "free software" is not the same as "free SIEM": you operate the indexers, dashboards, agents, upgrades, and scaling yourself, and the hiring market for people who want to babysit a self-hosted security stack is thin.
This comparison is for teams hitting that wall: you want the detection and monitoring capability, without the operations burden. We compare managed platforms and self-hosted alternatives on the criteria that actually decide the choice: who runs it, how pricing behaves as volume grows, and where your data falls under which jurisdiction.
Why teams look for a Wazuh alternative
- Operations burden: you run and scale the indexer cluster, dashboards, and agent fleet yourself, and upgrades are on you.
- Engineering time: tuning rules, decoders, and storage is a part-time job that competes with everything else on the roadmap.
- Scaling pains: high event volumes mean cluster engineering, not a support ticket.
- No vendor accountability: community support is good, but there is no SLA when ingestion breaks during an incident.
- The total cost of "free": infrastructure plus engineer hours often exceeds the price of a managed platform well before enterprise scale.
The alternatives
1. LogPulse
A managed, EU-hosted log management and SIEM platform on ClickHouse. Flat monthly pricing instead of per-GB metering, 50+ built-in MITRE ATT&CK-tagged detections, risk-based alerting that raises a handful of high-confidence notables instead of thousands of alerts, and Sigma rule import so existing detection content carries over. Data stays in the EU (GCP Amsterdam).
Best for: EU teams that want SIEM capability as a service, with predictable pricing and no cluster to run.
2. Graylog (Open / Security)
Open-core log management with a commercial Security tier. The open edition is a solid self-hosted log platform; SIEM features such as anomaly detection, correlation, and SOAR-style workflows live in the paid tiers.
Best for: Teams that want to keep self-hosting log management and are willing to pay for the security layer.
3. Elastic Security
SIEM built on the Elastic Stack, available self-hosted or as Elastic Cloud. Deep search capability and a large detection rule repository; sizing and tuning an Elastic cluster remains a real skill, and cloud pricing is resource-based.
Best for: Teams already invested in Elasticsearch expertise.
4. Microsoft Sentinel
Microsoft’s cloud-native SIEM on Azure, with strong integration into Microsoft 365 and Defender telemetry. Pricing is metered per ingested GB plus retention and automation, which is powerful but hard to predict.
Best for: Microsoft-centric enterprises with Azure expertise and budget flexibility.
5. Splunk Enterprise Security
The most mature SIEM on the market with an unmatched app ecosystem and the SPL query language. Licensing is ingest- or workload-based and is typically the most expensive option in this list by a wide margin.
Best for: Large SOCs with dedicated Splunk engineers and enterprise budgets.
6. Blumira
A US-based managed SIEM aimed at small and mid-size teams, known for fast deployment and per-user pricing. A strong option in its home market; hosting and jurisdiction are US-centric.
Best for: US-based SMBs that want a hands-off SIEM.
7. Security Onion
A free and open platform for threat hunting, network security monitoring, and log management, packaged as a distribution. Like Wazuh, capability is high and so is the operational commitment.
Best for: Network-monitoring-heavy teams that consciously choose the self-hosted path.
Side-by-side comparison
| Alternative | Model | Pricing model | You operate it? | EU data residency |
|---|---|---|---|---|
| LogPulse | Managed SaaS | Flat per month | No | Yes, EU-only by design |
| Graylog Security | Self-hosted / cloud | Tiered licence | Mostly | Depends on deployment |
| Elastic Security | Self-hosted / cloud | Resource-based | Partly | Configurable region |
| Microsoft Sentinel | Cloud (Azure) | Per-GB + meters | No | EU region, US provider |
| Splunk ES | Self-hosted / cloud | Ingest / workload | Partly | Configurable region |
| Blumira | Managed SaaS | Per user | No | US-centric |
| Security Onion | Self-hosted | Free (infra + time) | Yes | Wherever you run it |
