A complete SCADA package built to run entirely offline on an isolated or air-gapped network — live dashboards, alarm rules, and a local historian, with no outbound network calls at any point.
No credit card · No internet required · Windows 10/11 (64-bit)
Some networks can't and shouldn't touch the internet — critical infrastructure, defense-adjacent facilities, and plants under strict segmentation policy. This is SCADA built for exactly that: install it, connect your devices over the local network, and it never needs to phone home.
Once installed, SCADA Desktop makes no internet requests during normal operation — no license server callback, no telemetry, no cloud sync.
Connects to PLCs, meters, and drives over Ethernet or RS-485/RS-232 serial on the local network — no external protocol gateway required.
Build gauges, trend charts, and status indicators that render entirely from local data, with no dependency on an external rendering service.
Threshold alarms are evaluated and logged on the host machine; email notification can be disabled entirely for fully isolated segments.
Every tag is logged to a local database file. Export CSV reports manually via approved removable media when data needs to leave the segment.
The installer and license activation work without internet access, so the entire deployment can happen on a network with no outside connectivity.
Air-gapping is a deliberate security control, not a limitation to work around. Isolating the control network removes an entire class of remote attack surface — there is no cloud account to compromise, no API endpoint to probe, and no update channel that could be hijacked. For operators governed by IEC 62443 zone/conduit segmentation, NERC CIP, or internal policies that prohibit outbound connections from OT networks, a SCADA platform that simply doesn't need the internet is often the only compliant option. It also removes a practical dependency: a plant running air-gapped SCADA keeps monitoring, alarming, and historian logging fully functional even if the corporate network, ISP, or a cloud vendor has an outage. The tradeoff is that you manage updates and data export manually — SCADA Desktop's offline installer and CSV historian export are built around that workflow rather than assuming always-on connectivity.
Copy the installer to the air-gapped segment via approved media and run it — no internet connection is contacted during setup or license activation.
Add each PLC, meter, or drive as a Modbus TCP or RTU device over the local network or serial link and configure the tags you want to monitor.
Build your dashboard, set alarm thresholds, and let the local historian log data — the whole system keeps running with zero outbound connectivity.
| Consideration | Air-Gapped SCADA (Desktop) | Cloud-Connected SCADA |
|---|---|---|
| Internet required | No, ever | Yes, for remote access |
| Remote/multi-site access | No — local only | Yes, from any browser |
| Attack surface | Local network only | Includes cloud endpoints |
| Data export | Manual CSV via approved media | Automatic, cloud-hosted |
| Best fit | Isolated, high-security, regulated OT networks | Multi-site plants needing remote visibility |
It runs on a network with no physical or logical connection to the internet. SCADA Desktop installs as a standalone app, connects only to local Modbus devices, and stores everything locally.
No. Installation and license activation both work fully offline, so the whole deployment can happen on a network with no outside connectivity.
Yes. With no cloud dependency and no outbound network calls, it fits environments requiring strict OT/IT segmentation, such as critical infrastructure or IEC 62443-governed plants.
Yes. The local historian supports CSV export, so you can move trend and alarm history off the network using approved removable media or file transfer.
30-day full trial. Local HMI dashboards, alarms, and historian included — installs and runs with zero internet connectivity.
