Cybersecurity OT

Our own Industry 4.0 Cybersecurity Framework, aligned with NIST and ISA99/IEC-62443, to protect production environments without affecting operations.

Context and approach

Applying IT cybersecurity practices directly to OT environments usually fails: patching on the same schedule as corporate IT, or blocking traffic without understanding the industrial protocol, can stop production. OT cybersecurity requires an approach designed for the plant floor.

Netmask's Cybersecurity OT service is built on our own framework for Industry 4.0, aligned with NIST and ISA99/IEC-62443, covering segmentation, perimeter security, PLC backup, and passive vulnerability analysis.

What's included in this service?

  • Network area segmentation and interconnection — architecture aligned with the ISA95/IEC-62264 model (Field, Process, Supervision, Operations).
  • IT/OT perimeter security — deep packet inspection (Layer 7), IPS, content filtering, IPsec VPN.
  • PLC and plant station backup — guaranteed continuity in the event of operational incidents.
  • Passive vulnerability analysis — detection through non-intrusive inspection of OT traffic.
  • Secure remote and local access control — for vendors and contractors working on the plant floor.
  • OT incident management policy — documented and actionable, without stopping production.
Expected outcome

Protection that respects the production line

Your industrial environment gets a documented, standards-aligned cybersecurity posture that protects the plant without disrupting the operation it depends on.
