What it is
PatchMon provides a central dashboard for patch monitoring across Linux, FreeBSD, and Windows server fleets. Policies can schedule patches immediately, after a delay, or at a fixed time, with dry-run validation, approval workflows, and assignment by host or host group. Automated patch deployment is available on Linux and FreeBSD; Windows deployment is on the roadmap. Patch runs record who triggered and approved them, timestamps, policy details, affected packages, and command output. OpenSCAP CIS benchmark scans include per-rule results, severity, remediation guidance, and score tracking. Listed integrations span Proxmox LXC, Ansible, Docker, REST API, OpenSCAP, SSH, Windows RDP, and messaging and AI services. Monitoring agents connect outbound over WebSocket, use TLS in transit, and do not require root for monitoring operations. The free Community Edition is self-hosted under AGPLv3, with users responsible for the server, updates, backups, and uptime. Cloud plans start at $1 a month per endpoint. Cloud trials last 14 days, include Plus features, require a card at signup, and are not charged if cancelled before they end.
