Roundups of the self-hosted SIEM and network monitoring options, each comparing three or more open-source platforms on license, coverage and operating cost.
Wazuh, Security Onion and Graylog side by side, with OpenSearch and Elastic Security as backends or alternatives: what each covers (endpoints, network, logs), which licenses are OSI open source and which are source-available, and the paid tiers.
Suricata, Snort and Zeek compared for network IDS and network security monitoring: signature versus behavioral analysis, rule and script sources, licenses, outputs into a SIEM and hardware scaling.
Falco, Tetragon and Tracee compared for runtime threat detection on Kubernetes: eBPF approach, alerting versus in-kernel enforcement, rule and policy formats, governance and release activity. Also names KubeArmor as a fourth option without detailed facts.
Security Onion, Malcolm and standalone Arkime compared as complete network security monitoring stacks: bundled tools, packet capture, licenses, OT protocol coverage, Kubernetes and ISO deployment and the hardware each needs.
CrowdSec, Fail2ban and OSSEC compared for detecting and blocking attacks on Linux servers: log parsing, banning through firewalls or remediation components, shared blocklists, central management and licensing. Points to Wazuh for full SIEM needs.
Velociraptor, Wazuh and osquery compared for endpoint visibility, hunting and incident response without a commercial EDR: agents, query languages, central management, detection versus collection and licenses. Also names GRR Rapid Response.
