Frequently Asked Questions
Should I choose Wazuh or Suricata for enterprise security monitoring?
Choose Wazuh (`wazuh/wazuh`, 17.4k stars, GPL-2.0) when you need host-based intrusion detection (HIDS), file integrity monitoring (FIM), endpoint compliance (PCI DSS, HIPAA, NIST), and container workload vulnerability scanning. Choose Suricata (`OISF/suricata`, 6.8k stars, GPL-2.0) when inspecting raw network traffic at 10Gbps+ line rate, detecting lateral movement over TLS/HTTP/DNS, and extracting PCAP packet captures without placing agents on endpoints.
How do Wazuh and Suricata eliminate $5,000+/mo Splunk and CrowdStrike bills?
Splunk Enterprise SIEM charges aggressive daily ingest volume fees ($1.20/GB/day) while CrowdStrike Falcon charges $180-$300/endpoint/year. For an infrastructure of 500 endpoints and 50GB/day log volume, commercial software invoices exceed $5,000/month. Deploying self-hosted Wazuh managers paired with Suricata on dedicated NVMe instances costs ~$280/month total (-94.4%) with zero per-GB ingest caps and zero per-agent license taxes.
