Operational Technology (OT) & ICS/SCADA Cybersecurity
Safe, non-destructive cybersecurity assessments for critical infrastructure, SCADA networks, Distributed Control Systems (DCS), and programmable logic controllers (PLCs) complying with IEC 62443 and the Purdue Model.
// DIRECT EXECUTIVE BRIEFING: Can OT/ICS industrial control systems be pentested safely?
Yes. OT penetration testing requires specialized, non-intrusive methodologies following the IEC 62443 framework and Purdue Model. Parasym utilizes passive network monitoring, hardware-in-the-loop testbeds, and safe read-only protocol analysis (Modbus, DNP3, OPC-UA) to validate industrial security without causing production downtime or equipment damage.
