Security for the plant floor

Your PLCs, HMIs, and historians cannot run an endpoint agent — and your IT security stack was never designed for them. Cyber Pillar monitors production networks passively, without touching a controller.

Why Production Networks Get Breached

Manufacturing cybersecurity fails in predictable ways. These are the three weaknesses we find on almost every plant floor.

Flat Networks

Corporate and production sit on the same broadcast domain, so ransomware in the front office reaches the line.

Standing Vendor Access

Machine builders and integrators hold permanent VPN or cellular access that nobody audits.

No Inventory

Most plants cannot produce a current list of what is on the production network.

Controller-Safe by Design

OT cybersecurity only works if it cannot hurt production. Our monitoring model is built around that constraint and aligned with IEC 62443 and the NIST CSF Manufacturing Profile.

  • Passive Monitoring Only

    We deploy a network sensor at the IT/OT boundary (Purdue model Level 3 / DMZ). No agents on controllers, no active scanning of production assets, no traffic injected onto the plant network.

  • We Do Not Touch a Running Line

    Response actions on OT assets are recommended by our analysts and executed by your team under runbooks agreed in advance.

  • Framework-Aligned

    Assessments, detections, and reporting map to IEC 62443 and the NIST CSF Manufacturing Profile, so progress is measurable against recognized standards.
