It runs. It’s stable. But is it secure?
Modern operations blend old and new: Proven PLCs, smart sensors, remote access, cloud-connected historians…
But somewhere between uptime and innovation, security became a checkbox or worse— a half-documented “temporary” fix.
We were asked to review such a system.
It worked, until we looked closer:
Static IPs and tribal knowledge holding the network together
Firmware older than the field engineers
Remote access permanently in test mode
Zone segmentation based on a layout that hasn’t been valid since 2019
🔍 What we did?
We rebuilt the foundation — without touching the process logic:
✔️ Hardened key assets, patched the right places
✔️ Real OT segmentation, not just VLAN wishful thinking
✔️ Remote access secured, logged and monitored
✔️ System fully aligned with IEC 62443 — and with what your insurer actually expects
Same process. Same team.
But now with a system that’s resilient by design, not just by luck.
