Benchmark and uplift cybersecurity controls against OT standards (ISA/IEC 62443, NIST 800-82, ISO 27001 mappings).
•
Define and enforce standard OT reference architectures (segmentation, firewalls, VPN, DMZ/jump hosts, backup links, time-sync).

•
Partner with Corporate IT/Network/Security teams on secure IT/OT integration (identity, backups, SIEM, cloud data flows).
