NetPol vs Siemens SINEC Security Monitor

NetPol is self-hosted 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. Operators can set per-switch alarm thresholds, acknowledge or silence alerts, and review an action history. The software also supports SSH configuration backups, side-by-side diffs, and full restore. Polling classes range from Core at 30–90 seconds to Slow at 300–900 seconds, with jitter intended to protect OT control planes. NetPol can run on a local server, VM, or Raspberry Pi without a cloud dependency. Its maker says switch data stays on the customer’s server and routine monitoring uses no telemetry, cloud sync, or third-party data processors. PDF reports cover switch status, alert summaries, and recommendations. Lite costs A$1,000 a month per node for up to 25 switches; Medium is 1500.00 AUD and Pro is A$2,000 a month per node. A seven-day trial is listed; there is no free plan.
