Wazuh vs Graylog
Wazuh and Graylog both have free, open cores, and they start from different places. Wazuh is endpoint-first: its agent collects logs and also runs file integrity monitoring, vulnerability detection and configuration checks, with SIEM and XDR in one interface. Graylog is log-management-first: it collects, indexes and processes log data at scale, with its security analytics in the paid Graylog Security edition.
