OT security and industrial connectivity
Kroemtech helps small and medium sized industrial companies strengthen the security, connectivity, and visibility of their production (OT) environments.
We combine OT cybersecurity with hands on experience in industrial automation, machine software, embedded systems, and connected devices. This allows us to understand the complete system, from controller logic and machine behavior to networks, data platforms, and user interfaces.
Our work is focused around two closely connected areas: OT Security and Industrial IoT & Monitoring.
OT Security
Protect production with security designed for industrial environments
Industrial cybersecurity goes far beyond networks and firewalls. Security measures must work with PLCs, engineering workstations, legacy equipment, remote maintenance, and the operational requirements of production.
Our engineering background helps us understand which communications production really needs, where exposure can be reduced, and how security controls can be introduced without creating unnecessary operational risk.
Risk Assessments & Security Architecture
Gain a clear view of your OT environment, understand your most relevant risks, and define a practical roadmap for improvement.
Our work includes asset and network visibility, risk assessments, zones and conduits, segmentation concepts, and security architecture aligned with IEC 62443 principles.
Explore OT SecuritySecure Remote Access & Segmentation
Remote maintenance and connected production networks improve efficiency, but they can also create critical attack paths.
We help establish clear network boundaries, controlled remote access, and secure communication between users, systems, and production equipment.
OT Awareness Training
People are an essential part of your security architecture.
Our training helps shop floor personnel, engineers, IT teams, and plant managers recognize industrial cyber risks, avoid common mistakes, and respond effectively when an incident occurs.

Connect existing equipment and turn machine data into useful information
Industrial machines already generate valuable data, but that information often remains trapped inside PLCs, local PCs, proprietary interfaces, or isolated systems.
We connect these systems using modern industrial technologies and make the right data available for monitoring, analysis, reporting, and integration with other processes.
Machine Connectivity & Industrial Data
Connect PLCs, machines, sensors, test equipment, databases, and higher level systems using technologies such as OPC UA, MQTTS, APIs, and industrial communication protocols.
The goal is not connectivity for its own sake. It is reliable and secure access to the data that helps you operate, maintain, and improve production.
Condition Monitoring
Continuous monitoring gives you visibility into equipment, processes, and environmental conditions before small issues become operational problems.
We combine sensing, edge processing, secure connectivity, dashboards, alerts, and reporting into complete monitoring solutions.
Test & Production Equipment Modernization
Existing machinery can remain mechanically reliable long after its controls, software, or connectivity have become obsolete.
We modernize test and production equipment with updated controls, software, data acquisition, connectivity, and reporting while preserving the parts that still provide value.
Explore Test Equipment ModernizationWhat we monitor
Indoor Air Quality Monitoring
Our indoor air quality monitoring solution is one example of how we combine industrial IoT, secure connectivity, and actionable data.
Connected monitoring devices continuously measure parameters such as CO₂, particulate matter, VOCs, temperature, humidity, and other environmental indicators. Data is securely transmitted to a centralized platform for dashboards, alerts, reporting, and optional automated interaction with systems such as HVAC.
From a single monitoring point to larger multi site deployments, the solution combines sensing, secure connectivity, cybersecurity, and reliable data interpretation from the beginning.
Our perspective
From the Machine to the Network
Our technical background spans the complete industrial technology stack.
We understand how sensor signals become control decisions, how PLC logic interacts with machines, how production data travels through networks, and how that information eventually reaches applications, databases, and users.
That perspective matters as industrial systems become increasingly connected.
A machine becomes part of a network.
The network becomes part of the wider business infrastructure.
Every new connection creates new opportunities, but also new risks.
This is why we approach connectivity and cybersecurity together.
Why Kroemtech
Engineering expertise built around industrial reality
OT security with machine level understanding
We came to OT cybersecurity from inside the machine. Our experience with control systems and industrial software helps us understand what security decisions mean for the equipment and processes they protect.
Built for real production environments
Security and connectivity must coexist with availability, safety, maintenance, and existing equipment. Our solutions are designed around those operational realities.
Practical for small and medium sized companies
Improving OT security or connectivity does not have to begin with a large transformation project. We focus on clear priorities and improvements that can deliver value step by step.
Security by design
Secure communication, authentication, access control, segmentation, updates, and system hardening are considered from the beginning, not added after the system is built.
Our approach
Start With What Matters
Not every problem needs a complete redesign, a new platform, or another layer of complexity.
We focus first on the risks, limitations, and opportunities that have the greatest impact on your operation.
From there, we define practical improvements that can be implemented step by step and remain maintainable as your systems evolve.
