What Technilog does

Technilog is a French private software publisher founded in 1985 and headquartered in Saint-Rémy-lès-Chevreuse, near Paris. The company builds multiprotocol industrial communication software — most notably the DevI/O communication front-end, the WebI/O centralized supervision platform, and the recently launched Qualitrack intelligent traceability module for connected torque tools. Its core technology unifies more than 150 industrial protocols (OPC UA, MQTT, Modbus, BACnet, LoRa, Sigfox, REST, CT503, etc.) to bridge operational technology (PLCs, sensors, IoT devices) with enterprise IT systems (SCADA, MES, ERP, BI, CMMS). DeepConnect, introduced in 2022, layers automatic thresholding and behavioral projection analytics onto the data pipeline to support predictive maintenance and anomaly detection.

The company monetizes through a mix of enterprise software licenses (perpetual and subscription/SaaS for WebI/O), annual maintenance and support contracts (AMS/TMA), and project-based professional services covering integration, training, and custom development. Pricing is opaque and handled entirely through direct enterprise engagement; there are no published tiers or self-serve channels. Distribution is exclusively direct field sales supported by pre-sales consultants, targeting large industrial organizations (aerospace, automotive, manufacturing), infrastructure operators (water, energy, gas), and public authorities managing distributed assets. Verified customer logos include SNCF Réseau, Dassault Aviation, Airbus, ArianeGroup, Safran, Stellantis, IRSN, Engie Solutions, Saur, Ville de Paris, Conseil Départemental 13, Aquafin, and Regaz.

Technilog deploys its software on 50,000+ sites globally. Strategic milestones include the 2007 integration into the Applitude group, sustained R&D investment at 25% of sales since 2010-2011, OPC Foundation and BACnet Association memberships, ISO 27001 compliance for WebI/O, the 2022 AI integration milestone, the 2025 SNCF national tender win (80 DevI/O racks across 100+ railway assets), and the October 2025 launch of Qualitrack. The company maintains a partnership ecosystem spanning Alstom, Hitachi, Vossloh, SIS, Sofrel, and the Smart Buildings Alliance, and exhibits at industry events such as Global Industrie Paris.

Revenue model

1. Software Licenses (DevI/O, WebI/O, Qualitrack): Technilog sells software licenses for its DevI/O multiprotocol front-end, WebI/O supervision platform, and Qualitrack traceability solution. These are deployed either on-premise or in SaaS mode. Licensing is enterprise-oriented, with pricing based on deployment scale, number of servers/devices, and number of sites. The company also offers perpetual licenses alongside subscription models for SaaS deployments.
2. Annual Maintenance and Support (AMS / TMA): Technilog extends sales contracts through an after-sales support team offering Application Management Services (AMS/TMA). This covers technical support, software updates, bug fixes, and remote diagnostics. These contracts provide recurring maintenance revenue and reinforce customer stickiness.
3. Professional Services (Integration, Training, Custom Development): Technilog provides pre-sale consulting, production launch support, and custom development services for specific customer projects. As an approved training organization (No. 11.78.81540.78), the company also offers paid training programs to build customer competency. Professional services are quoted on a project basis and complement the software revenue.
4. SaaS / Cloud Subscription (WebI/O): WebI/O is offered in SaaS mode alongside its On-Premise deployment option. SaaS subscriptions provide centralized supervision as a recurring service, billed on an annual or multi-year cadence. This provides predictable recurring revenue and lower entry barriers for certain customer segments.

Core offering

Technilog develops and sells multiprotocol industrial communication software for OT/IT convergence, including the DevI/O communication front-end, the WebI/O centralized supervision platform, and the Qualitrack intelligent traceability solution. Its products enable industrial organizations to acquire, supervise, and trace data from heterogeneous equipment across 150+ industrial protocols. The portfolio targets manufacturers, infrastructure operators, and public authorities requiring interoperability between field-level devices and enterprise IT systems.

Product overview

Technilog offers a unified software suite centered on three core products: DevI/O (multiprotocol communication front-end for data acquisition and unification), WebI/O (centralized supervision platform for monitoring and remote control), and Qualitrack (intelligent traceability module for connected torque tools). DevI/O serves as the foundational data collection and protocol translation layer, WebI/O provides the centralized monitoring and management interface, and Qualitrack extends the ecosystem specifically for manufacturing quality and traceability. Together, they form a complete chain for collecting, unifying, securing, and distributing industrial data across heterogeneous environments.

Broad incumbents

• Schneider Electric (EcoStruxure): Schneider Electric's EcoStruxure platform combines industrial automation, energy management, and IoT connectivity for plants, buildings, and grids. EcoStruxure's industrial edge and connectivity layers overlap with DevI/O and WebI/O, and Schneider's broader portfolio (including AVEVA partnership) represents a much larger competitive force in the same accounts.
• AVEVA: AVEVA (formerly Wonderware) provides a broad industrial software portfolio spanning SCADA, MES, asset performance, and digital twin — overlapping with Technilog's DevI/O and WebI/O offerings. Its CONNECT platform includes edge connectivity and multi-protocol device drivers, positioning it as a broad incumbent in the industrial OT/IT space.
• PTC (ThingWorx): PTC's ThingWorx is an enterprise IIoT platform combining Kepware connectivity, analytics, and augmented reality for industrial use cases. It competes with Technilog's broader DevI/O + Qualitrack + WebI/O stack, particularly for manufacturers seeking a single vendor for connectivity, analytics, and visualization.
• Siemens (Industrial Software): Siemens offers SIMATIC, REX6000, MindSphere, and the OPC UA ecosystem with extensive industrial communication capabilities for factory automation. It addresses the same industrial connectivity and supervision use case as Technilog, particularly in European manufacturing and process industries where Siemens holds strong incumbency.

Direct peers

• Software AG (Cumulocity IoT): Software AG's Cumulocity IoT is an edge-to-cloud IoT platform with multi-protocol device management, asset connectivity, and analytics — directly comparable to Technilog's DevI/O + WebI/O stack for industrial and infrastructure operators seeking a managed connectivity and supervision solution.
• Kepware (PTC): Kepware is the leading standalone OPC/multiprotocol industrial connectivity server, now part of PTC's ThingWorx. It competes directly with Technilog's DevI/O by connecting PLCs, sensors, and industrial equipment to enterprise applications across 150+ protocols — addressing the same OT/IT integration use case for manufacturing and infrastructure operators.
• HMS Networks: HMS Networks (Anybus, Ewon, Ixxat) provides industrial communication gateways, remote access, and connectivity solutions bridging fieldbus, industrial Ethernet, and IoT protocols. It targets the same multiprotocol OT/IT integration problem as DevI/O, particularly in factory automation and remote equipment monitoring.
• Inductive Automation (Ignition): Ignition by Inductive Automation is a web-based SCADA/MES platform with extensive multi-protocol device connectivity via its MQTT and OPC UA modules. It competes with Technilog's combined DevI/O + WebI/O offering, particularly for industrial customers seeking unified supervision and unlimited-client licensing.

Emerging players

• Litmus Automation: Litmus Automation provides an edge-to-cloud Industrial IoT data platform with protocol translation, edge computing, and analytics. It targets the same industrial connectivity and data unification problem as DevI/O, particularly for manufacturers building data pipelines for AI and machine learning.
• Cogent DataHub / Skkynet: Cogent DataHub and Skkynet provide industrial middleware for protocol bridging, OPC UA/MQTT tunneling, and bidirectional data exchange between PLCs and enterprise systems. They are niche competitors in the multiprotocol industrial connectivity space where Technilog's DevI/O operates.
