Wazuh could replace a number of tools that we are aggregating inside AniNIX/Sharingan:

lynis
arch-audit
graylog+elasticsearch+mongodb
rkhunter
AIDE

However, the agent is heavy, wanting gigs of storage, two cores, and a gig of memory. This is a tradeoff, at the moment -- the syslog aggregation would be the same, but we are using daily inspections with our host tool stack to reduce persistent resource utilization. This makes our current stack more cost-effective. We can revisit this as resources become cheaper.

Example deployment on Arch:

Note, agent-based security tools tend to require privileged access for the agents, which makes remote access to the dashboard a major issue. In our deployment, agents file data via syslog to the aggregator which prevents compromise of the aggregator from infecting servers. Examples of why this is bad:
