NetPol vs Radiflow iSID

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.

Radiflow iSID provides OT network visibility, threat detection and monitoring for industrial operations and critical infrastructure. It passively analyzes mirrored network traffic to discover OT assets and build an inventory that records their roles and impacts on the environment. The system learns normal network, asset and communication behavior, then detects deviations alongside known threats and vulnerabilities using threat intelligence, SNORT-based and common attack signatures, and CVE mapping. It also monitors configuration changes in PLCs and other network devices without disrupting operations. Deployment can be centralized with iSAP Smart Collectors, placed locally at remote sites, or use a mix of both. The iCEN web interface offers enterprise-wide and site-specific views and centralized management of multiple iSID instances. MSSPs can manage multiple customers with client-based view permissions. A documented Cisco ISE integration shares OT asset context through pxGrid and supports Adaptive Network Control quarantine policies. The iSID 6.0 guide specifies Google Chrome for browser management. Radiflow describes its solutions as serving industrial enterprises and utilities, including critical infrastructure operators. Pricing is available on request.
