Wazuh SIEM vs. Commercial Solutions for MSPs

Updated: August 2026

Splunk's traditional ingest pricing model charges approximately $1,800 annually per GB/day, with 100GB/day deployments facing base licensing costs around $69,000 annually while Wazuh delivers the same security operations for zero licensing fees with only infrastructure costs. A growing community of 12.8k GitHub stars and Fortune 100 organizations is discovering how open-source SIEM platforms can transform SOC economics without sacrificing enterprise detection capabilities.

MSPs operating security operations centers face a critical challenge: commercial SIEM solutions consume 15-25% of SOC revenue through licensing alone. The newer Splunk workload pricing model allows unlimited data ingestion but ties costs to search activity, with 100GB/day deployments typically requiring 2-5 SVCs and costing $200,000-$400,000 annually. However, enterprise-grade open-source alternatives now provide equivalent functionality with dramatically different cost structures.

This technical comparison analyzes Wazuh versus commercial SIEM platforms across MSP-specific requirements including multi-tenancy, cost predictability, and detection capabilities. We examined real MSP deployments handling 500GB-2TB daily log volumes to demonstrate actual implementation differences and total cost of ownership implications.

Wazuh Open Source Deployment Costs

Hidden Cost Analysis

Commercial SIEM Additional Expenses:

• Annual price increases ranging from 5-9% depending on contract length
• Multi-tenancy requiring separate instances per tenant
• Vendor lock-in migration costs exceeding $100,000
• Complex licensing negotiations and compliance audits

Wazuh Deployment Considerations:

• Staff training time: 40-80 hours initial learning curve
• Community support dependency with 24-48 hour response times
• Custom rule development requiring in-house expertise
• Infrastructure costs varying from $125 monthly for small deployments to $3,938 monthly for large enterprise clusters

Many of these concerns reflect common myths about open-source MSP tools that don't hold up under scrutiny.
