What Trihedral Engineering does

Trihedral Engineering Limited, founded in 1986 and headquartered in Bedford, Nova Scotia, Canada, develops and sells VTScada, an integrated SCADA (Supervisory Control and Data Acquisition) and HMI software platform used for industrial monitoring and control. VTScada is built on one of the world's first reactive programming languages, with a single-install architecture that bundles polling management, historian, trends, reports, application version control, alarm management, and cybersecurity (IEC 62443 Maturity Level 3 certified) into one license. The product scales from 50 I/O on a laptop to multi-million tag distributed systems, supports over 100 native device drivers, and ships in a commercial edition plus a free VTScadaLIGHT tier.

Trihedral serves customers across water and wastewater utilities, oil and gas, power generation, broadcasting, marine vessels, manufacturing, airports, and food and beverage, with named deployments at the City of Houston's $1.4B NEWPP water project, Aker Solutions on 190+ offshore platforms, the two largest North American energy producers, North America's largest broadcast system, and the Canadian Coast Guard. The company operates nine offices across Canada, the United States, and the United Kingdom, and reaches 166 countries through a global network of certified VTScada integrators. Trihedral is a wholly owned subsidiary of Delta Electronics following a 2020 acquisition, and it has reported continuous growth in sales and installations for 37 consecutive years.

Revenue is generated through annual commercial VTScada software licenses (priced by concurrent thin-client users), SupportPlus 24/7 support contracts, and engineering and integration services, with a freemium entry point via VTScadaLIGHT and a 90-day trial. Distribution combines direct enterprise field sales through regional offices with a certified system-integrator channel.

Partnerships

Three partnerships are on record, tiered core and flagship.

• Owl Cyber DefensecoreTechnology or Integration · 2 June 2026Owl Cyber Defense and Trihedral Engineering announced a technology integration enabling secure transfer of operational data from OT environments to IT systems using VTScada and Owl's data diodes. This solution eliminates cyber risks associated with data transfer and has been deployed at U.S. cities including Houston and Nashville in water and wastewater facilities. The partnership aims to extend secure data mobility across critical infrastructure sectors with SCADA systems.
• Madsen GroupcoreImplementation/ SI/ Consulting PartnerVTScada's partnership with Madsen Controls reflects a shared commitment to delivering resilient, mission-critical solutions for clients operating in demanding environments. Madsen Controls brings deep expertise in system integration and local support, helping ensure Coast Guard systems remain reliable, secure, and easy to maintain. Together the organizations have supported deployment and ongoing success of advanced monitoring and control solutions for Canada's vast coastline.
• Aker SolutionsflagshipOEM/ Whitelabel/ Licensing PartnerMajor solution provider Aker Solutions standardized on VTScada for their Subsea Monitoring and Control System (SMACS). This partnership has resulted in VTScada being installed on over 190 oil platforms worldwide through the SMACS system.

Scale indicators10 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• GE Digital (iFIX / CIMPLICITY): GE Digital's iFIX and CIMPLICITY are legacy SCADA/HMI platforms used in power, water, and O&G — directly substitutable for VTScada in process industries, with stronger enterprise OT integration through GE's broader Predix and APM stack.
• Siemens (SIMATIC WinCC): Siemens offers WinCC as the SCADA/HMI layer within its SIMATIC automation portfolio. Competes head-to-head with VTScada in power generation and manufacturing, typically as part of a broader Siemens plant-automation bundle.
• Rockwell Automation (FactoryTalk View): Rockwell's FactoryTalk View SE and View ME are SCADA/HMI products bundled with Allen-Bradley PLCs. They overlap with VTScada in manufacturing, F&B, and water, and benefit from Rockwell's installed PLC base and integrator network.
• Honeywell (Experion / HMIWeb): Honeywell's Experion process-control and HMIWeb/SCADA offering competes with VTScada in power generation, O&G upstream, and water, especially where customers want a single-vendor DCS-plus-SCADA solution.
• Emerson (Movicon.NExT): Emerson's Movicon.NExT SCADA/HMI platform competes with VTScada in O&G, water, and power, and is tightly integrated with Emerson's DeltaV DCS — a typical advantage in larger process plants.

Others

• Canary Labs: Canary Labs provides the Canary Historian, an industrial historian and trending platform that frequently sits alongside VTScada in water/utilities and overlaps with VTScada's native historian — making it both complement and competitive substitute in some deployments.
• OSIsoft / AVEVA PI: OSIsoft's PI System is a dominant industrial data historian and asset-framework platform — complementary rather than directly competing with VTScada, but increasingly overlapping as customers consolidate OT data architectures around PI.

Direct peers

• AVEVA (Schneider Electric): AVEVA, now part of Schneider Electric, ships Wonderware/InTouch and the AVEVA Industrial Platform — direct SCADA/HMI competitors to VTScada with overlapping water, power, and O&G customer bases and substantially larger enterprise reach.
• ICONICS (Mitsubishi Electric): ICONICS' Genesis64 HMI/SCADA suite and AssetWorx — now under Mitsubishi Electric — competes directly with VTScada as an independent, integrator-friendly SCADA/HMI platform serving water/wastewater, O&G, and facilities automation.
• Inductive Automation: Vendor of Ignition, a modern cross-platform SCADA/MES stack. Closest comparable to VTScada in being independent, vertical-agnostic, and integrator-driven, with strong adoption in water/wastewater and a more recent cloud-friendly architecture.
