NetPol
NetPol is network monitoring software for OT, SCADA, and industrial networks.
What NetPol is
NetPol is network monitoring software for OT, SCADA, and industrial networks. It polls managed switches using SNMP v2c and displays CPU, memory, interface status, errors, and uptime. Automatic CDP and LLDP discovery creates a live map of device relationships and link states. Users can set per-switch alarm thresholds, acknowledge or silence alarms, and review action history. NetPol also supports SSH configuration backups, side-by-side differences, and full restore. Polling classes range from Core at 30–90 seconds to Slow at 300–900 seconds, with Standard and Maintenance options and jitter intended to protect OT control planes. It runs self-hosted on a local server, VM, or Raspberry Pi without a cloud dependency. The maker says switch data stays on the customer’s server and day-to-day monitoring uses no telemetry, cloud sync, or third-party data processors. PDF reports summarize switch status, alerts, and recommendations.
Good
- Live device and link maps use CDP and LLDP.
- Per-switch alarms can be acknowledged or silenced.
- SSH backups include diffs and full restore.
- Runs locally without a cloud dependency.
- PDF reports summarize status and alerts.
Watch out

Who it suits
NetPol suits industrial operators and OT service providers monitoring managed switches, including teams in mining, utilities, water, manufacturing, oil and gas, and transport infrastructure. It is aimed at deployments that can run a self-hosted system and enable SNMP v2c on switches.
Verdict
NetPol combines switch monitoring, topology discovery, alarms, backups, and reporting in a self-hosted package for industrial networks. Check platform limits and per-node plan details against the intended deployment before choosing it.
