Security
Self-host Wazuh on a VPS
Open-source SIEM and endpoint detection.
Collect logs, detect intrusions and monitor file integrity and vulnerabilities across your hosts from one stack.
Why self-host Wazuh?
Wazuh gives you a genuine SIEM and HIDS you can run yourself, for the price of the server rather than per-GB licensing.

Practical tips
- Give Wazuh its own database user with rights only on its own schema.
- Reverse-proxy Wazuh and terminate TLS at the proxy so certificates are managed in one place.
- Take a VPS snapshot before major upgrades so you can roll back cleanly.
- Keep Wazuh patched — most self-hosting incidents are unpatched software.
