Business promise
A failure should become a forecast, not a surprise
The IoT page is about visibility into physical assets: equipment state, downtime risk, telemetry and decisions made before an incident.
Industrial IoT, SCADA integration, predictive maintenance, digital twins for critical infrastructure. From sensor to CEO dashboard.
The IoT practice covers design and implementation of industrial IoT systems: telemetry collection from sensors, SCADA integration, edge processing, time-series analytics, predictive maintenance, digital twins.
We work primarily for critical infrastructure (energy, oil & gas, water supply) and manufacturing holdings, where reliability matters more than features, and OT environment cybersecurity is a separate layer of complexity.

The real IoT complexity is not sensors. It is connecting OT reality, IT architecture and business metrics without risking production.
We do not put sensors everywhere. We choose equipment where downtime is expensive, verify historian data and build a pilot with the OT team.
Spare parts savings are a side effect. Main value — ability to schedule maintenance for night shift instead of stopping the production line in daytime. Without this understanding, ROI calculations do not add up.
IT team thinks SLA 99.5%. OT team thinks "zero downtime on this turbine in 20 years". Integration is done via DMZ with one-way data diodes for critical flows, not through usual enterprise patterns.
Before building a digital twin, you need at least 12 months of historical data from measurement points. Without this the model cannot be calibrated and gives inaccurate predictions.
It is more honest to say "you do not need this yet" than to sell an engagement that will not deliver ROI.
Inventory of sensors, controllers, SCADA systems. Audit of historian data. Interviews with OT team to understand operational constraints.
Design of edge collection layer, time-series data lake, ML pipeline for predictive maintenance, DMZ for OT/IT integration with cybersecurity-by-design.
Usually — a critical unit with known failure history. Pilot proves predictive model precision/recall and operational adoption with OT team.
Phased expansion to full equipment fleet. Adapting models by equipment type. Developing digital twins for most critical systems.
Model drift monitoring, retraining for new failure patterns, integration with maintenance management, regular OT cybersecurity audits.
Project lead: AZIOT (IoT platform, edge collection, SCADA integration) and Softengi (ML models for predictive maintenance, digital twins).
Brought in when needed: Softline (OT cybersecurity, NIS2 compliance for critical infrastructure).
They enter the project with the idea "let's install sensors and figure out later what to do with them". A year later — 10 TB of historical data and zero operational insight.
What we do instead: we start from the business problem: which equipment is critical? which failure modes do we want to predict? Only then we choose sensors.
IT team opens a VPN tunnel into the OT segment "for analytics". Six months later — ransomware attack via compromised IT user reaches OT.
What we do instead: DMZ with one-way data diodes for critical flows. The OT segment is never accessible for back-queries from IT.
Data scientists train models on historical data without OT engineers. The model produces alerts that OT ignores because they do not correlate with actual failure patterns.
What we do instead: OT engineer as model co-author. Every new model version — joint review with OT before deployment.
Each example shows the client-side story: what was getting in the way, what changed, and what result the team got.

With the most critical — equipment whose failure costs most per incident. Then — equipment with known failure history (for model training). Avoid "new flagship" equipment that has not accumulated 12 months of data yet.
Pilot on one equipment unit — 3–4 months. Full coverage for critical infrastructure — 12–18 months. First truly reliable predictions — 6–9 months after production start (because validation on real failures is needed).
For typical scenarios (monitoring, predictive maintenance) — yes, with outsourced OT expertise. For critical infrastructure — categorically no. The OT team must be in-house, because equipment knowledge is an asset that cannot be outsourced.
IEC 62443 as base framework. Principles: (1) network segmentation with DMZ; (2) one-way data diodes for critical flows from OT to IT; (3) never allow back-queries from IT to OT; (4) separate IAM for OT; (5) regular OT-specific penetration testing.
Digital twin — a software copy of a physical object with real-time telemetry and physical model. Pays off for critical equipment where experiment errors are costly. Does not pay off for typical equipment where predictive maintenance is enough.
Real projects rarely fit in one competency. See which other areas we work in.
30-minute discovery call with an IoT architect. We will discuss equipment, historical data and realistic expectations.
Intecracy Group does not force a single delivery team. We clarify the task, identify the required competencies and help involve the relevant alliance members.
