– Perform asset inventory mapping, network zoning, and data flow analysis
– Identify vulnerabilities in OT environments (PLC/SCADA/DCS/RTU systems)
– Develop risk treatment plans, cybersecurity roadmaps, and disaster recovery plans
– Create network architecture diagrams and zoning segmentation designs
2. Implementation & Configuration
– Configure and deploy OT firewalls, switches, and segmentation appliances (e.g., Fortinet, Juniper, Hirschmann, Cisco, Moxa)
– Implement endpoint protection, application whitelisting, patching, and USB control solutions

– Hands-on experience with industrial firewalls, SIEM, EDR, backup systems
– Familiarity with OT protocols (Modbus, OPC, DNP3, IEC 61850, etc.)
– Understanding of standards: ISA/IEC 62443, NIST SP 800-82, ISO 27001 (with OT alignment)
– Experience with cloud security technologies (e.g., AWS, Azure) is considered a strong plus, especially in environments involving IT/OT integration or industrial digitalization.
– Ability to work independently on customer sites and lead technical delivery activities
Preferred Certifications (any of the following):
– GICSP, ISA/IEC 62443, CISSP, CRISC, CISM
– CCNP Security, Fortinet NSE, CySA+, CEH, or equivalent
