OT / ICS / IoT Security
OT/ICS and IoT industrial systems are growing targets for directed attacks. We assess PLCs, SCADA, HMIs, industrial protocols (Modbus, DNP3, OPC-UA, EtherNet/IP) and IoT/IIoT devices with an approach that minimizes operational risk and aligns with IEC 62443 and NIST CSF.

Reference framework
We assess industrial security under the IEC 62443 zones-and-conduits model (extended Purdue Model), validating the 7 foundational requirements (FRs) at each level.
Corporate IT layer: ERP, offices, internet. The most common entry point for OT-targeted threats.
Industrial DMZ between IT and OT: jump servers, replication servers, centralized AV, traffic validation.
Historian, MES, batch management — operational management layer with interfaces to IT and OT.
Operator stations, SCADA, HMIs, process engineer. The human-machine interface.
Logic controllers: PLCs, RTUs, SIS. Real-time control logic, industrial protocols.
Sensors, actuators, motors, valves. The physical layer of the production process.
Unique identification of humans, software, devices. Authentication proportional to risk.
Restriction of actions authorized per user and context. Least-privilege principle.
Integrity of software, data and communications. Detection of unauthorized changes.
Resilience against DoS and degradation. Operational continuity as a security requirement.
OT environments do not tolerate the intrusive techniques common in IT: an aggressive scan can halt a production line. We therefore use passive techniques, agreed windows and, where possible, lab or replica environments. Availability comes first.
It is the separation between the corporate network and the industrial network. When that boundary is porous, a compromise in corporate email can end up reaching a PLC. We verify that segmentation truly exists and not only on the network diagram.
It is the international reference standard for the cybersecurity of industrial automation and control systems. It defines security levels, zones and conduits, and it is the framework we align the assessment with.
Yes. We assess firmware, communication protocols, management interfaces and default credentials, both in consumer devices attached to the corporate network and in connected industrial equipment.
