Meet the Contenders: Trihedral & Canary Labs
Trihedral Engineering Systems is a Canadian-based company founded in 1986. It’s best known for its flagship SCADA software, VTScada. The platform has built a reputation for its integrated design, scalability, and strong visualization tools. Trusted in sectors like water treatment, oil & gas, manufacturing, and utilities, VTScada offers a full suite of monitoring and control capabilities.
Their strength lies in delivering a unified platform without a patchwork of third-party add-ons. VTScada’s all-in-one architecture minimizes reliance on multiple external modules, which improves speed, reliability, and user experience.
Canary Labs Systems, founded in 1985 and now part of the Certec-EDV group, is a Pennsylvania-based software company with a strong foothold in scalable, fast, and cost-effective data historian solutions. Their signature product, the Canary Historian, is coupled with SCADA visualization through partnerships and integrations, rather than offering a traditional SCADA platform. Unlike Trihedral, Canary’s focus is on storing time-series data and presenting it with lightning-fast querying capabilities and visual tools like Axiom.
Canary is perfect for organizations heavily focused on data retention, reporting, and long-term analytics—especially where visualizations and insights on performance indicators are mission-critical.
Deployment Approach: Unified vs Modular
Trihedral’s VTScada is often referred to as a “one-box solution.” It’s built to handle everything internally—from HMI, alarms, reports, historian data, redundancies to security—all baked right in. This design choice simplifies system architecture and reduces the need for third-party components.
Canary Labs, on the other hand, takes a more modular approach. While the Canary System can function as a powerful back-end historian, you’ll typically require separate tools for HMI/SCADA functionality. Most customers pair it with external system integrators like Ignition by Inductive Automation or other open-source HMI layers.
Pros of Trihedral’s Unified Design:
- Quick deployment with fewer integration headaches
- Fewer vendors to manage
- Higher reliability due to tighter integration
Cons:
- Less customizable compared to modular open architectures
- Some features may feel overwhelming for smaller installations
Pros of Canary’s Modular Design:
- Exceptional data handling speed and efficiency
- More flexibility in visualization tools and customization
- Easier to adopt in systems where historian functionality is the focus
Cons:
- Requires integration with third-party tools for full SCADA visualization
- Higher setup complexity for users wanting a full SCADA build-out
User Experience and Interface
VTScada offers a well-designed and intuitive interface that’s customizable and user-friendly. Operators can visualize operations, acknowledge alarms, trigger actions, and analyze data from the same dashboard. Everything is centralized, which speeds up learning curves and daily usage.
Canary’s visualization platform—Axiom—is web-based and responsive. It’s geared more toward data analysts or engineers looking to spot trends and generate reports rather than operators needing high-frequency control interfaces.
A good analogy here is: while VTScada is like a performance sedan ready to race right out of the box, Canary is like a modular racing kit—you pick the parts and assemble exactly what you want, but you’ll need time and tuning.
Performance and Scalability
Both platforms shine when it comes to performance, but in different ways.
Trihedral (VTScada) is built to scale with your project. Whether you’re managing a small wastewater facility or hundreds of remote oil rigs, VTScada scales up elegantly with minimal architectural changes. High-speed data polling, native redundancy, and seamless failovers make it robust for critical environments.
Canary Labs focuses primarily on data. Its historian can handle millions of data points quickly and without slowing down. It’s especially effective in energy operations, utilities, and manufacturing environments where time-series analysis determines operational efficiency and compliance.
One notable performance edge is Canary’s ultra-compressed time-series storage engine that doesn’t compromise speed. It minimizes disk use and accelerates data visualization. Here’s how they compare visually:
| Feature | Trihedral VTScada | Canary Historian |
|---|---|---|
| Primary Focus | Full SCADA Suite | High-Speed Data Historian |
| Real-Time Control | Yes | Limited* |
| Data Compression | Average | High |
| Custom Dashboards | Yes (HMI + Trend Tools) | Yes (via Axiom) |
| Modular Integrations | Limited | Extensive |
| Ease of Deployment | Plug & Play | Advanced Required |
*Canary focuses on data storage and analysis, not real-time control interfaces.
Security and Reliability
Security is no longer just a feature—it’s a requirement. Trihedral takes cybersecurity seriously with VTScada’s role-based access controls, Active Directory integration, encrypted data transport, and built-in backup and redundancy protocols.
Canary also offers robust security, especially at the data storage and access levels. It utilizes read-only architecture to eliminate potential overwriting issues and support for Windows authentication. However, real-time control security typically falls to whatever front-end SCADA you integrate.
If your business involves critical infrastructure or regulated markets, Trihedral’s consolidated, secured environment might offer more peace of mind.
Support Services and Community
Both companies offer technical assistance, training, and developer resources. But there are differences in approach.
VTScada wins on direct developer support. Since everything’s under one roof, issues rarely end in finger-pointing between vendors. Their documentation is extensive, and users have access to online training portals, a supportive forum, and even direct consultations. This is a significant perk.
Canary’s support is also responsive, and the company provides in-depth training materials, but because their approach is modular, troubleshooting often requires cross-vendor conversations. The community forums are helpful, especially for larger Canary users and integrators working with multiple vendors.
Cost Styles: Licensing & ROI
Trihedral uses a traditional licensing structure based on the number of I/O points or tag counts. While the upfront cost can seem higher, the all-in-one package means fewer expenses down the road—no software stacking or additional modules needed.
Canary’s licensing can be more affordable initially, particularly if you’re only in need of a historian. Their pay-for-what-you-use scheme makes sense for companies just starting with analytics or that already have another SCADA system in place.
So essentially:
- VTScada = Higher initial cost, but fewer moving parts long term
- Canary = Lower entry cost, but you’re responsible for assembling your toolbox
Industries and Use Cases
Trihedral shines in:
- Water and wastewater systems
- Oil and gas
- Power distribution control
- Food & beverage manufacturing
Canary is optimal for:
- Long-term data analysis and reporting
- Energy management and compliance
- IOT applications
- Integration with existing SCADA stacks
Final Thoughts: Choosing the Right SCADA Partner
No two operations are exactly the same, and the “best” SCADA solution really depends on your business needs. Here’s a quick summary to help guide the decision:
Choose Trihedral VTScada if you:
- Want a complete SCADA platform out-of-the-box
- Need high reliability with built-in redundancy
- Have critical infrastructure needing centralized control
- Prefer dealing with a single vendor across the board
Choose Canary Labs if you:
- Need a high-speed data historian at the core
- Already have a SCADA/HMI system and want to improve data analysis
- Want ultimate flexibility in how you visualize and store data
- Operate in environments with large volumes of time-series data
For hybrid use cases, many enterprises today use both, integrating Canary’s Historian within a larger Trihedral (or other) SCADA framework, combining best-of-breed tools.
