+The Mistborn Security Operations Center provides SIEM services with Wazuh. The Wazuh Manager requires an Open Distro for Elasticsearch backend. When the Mistborn host has >8 GB RAM the provided Elasticsearch backend can be used. Just click "Start Wazuh" on the `Security Center` page and enjoy your Enterprise-grade SIEM. Wazuh agents can be installed on just about any OS and all Wazuh agent traffic is communicated over the Wireguard connections. Instructions for adding endpoint agents can be found within Wazuh itself.
