Summary

PatchMon is an enterprise-grade platform for monitoring, managing, and securing Linux fleets, offering operations teams a single pane of glass for real-time visibility into package health, compliance, and system status. It provides essential tooling, automation, and auditability for infrastructure teams managing environments of any scale.

How It Works

The platform employs lightweight, outbound-only agents that communicate securely with the PatchMon server, eliminating inbound port requirements on monitored hosts.
