Safety-first assessments of SCADA, PLCs, HMIs and industrial networks, aligned with IEC 62443 and the Purdue model, with passive techniques wherever live plant is involved.
Operational technology was built for reliability, not security, and it is increasingly connected to IT networks and the internet. A single weak link between the two can stop production or worse.
SafCY tests industrial environments without putting operations at risk. We start passively, agree every active step with your engineers, and test against simulators or offline equipment where we can.
What we cover
- Asset discovery of PLCs, RTUs, HMIs and historians from passive traffic
- IT/OT segmentation across Purdue levels 0–4 and the industrial DMZ
- Protocol review of Modbus, DNP3, IEC 61850, OPC UA and others
- Remote access paths used by vendors and integrators
- IEC 62443 gap assessment for zones, conduits and security levels
