1 Die Herausforderung
Aging firewalls across 14 distributed substations had divergent rule sets, no central change control, and inconsistent IDS coverage — a structural risk for an OT-adjacent network.
2 Unser Vorgehen
WPROIT's NSE-certified team rolled out a unified FortiGate fabric with a golden-config baseline, central policy management, and a phased migration plan that preserved operational continuity at each substation.
3 Ergebnis
All 14 sites are now under a single policy plane with unified IDS/IPS coverage; quarterly audit findings on perimeter consistency dropped to zero.
"A genuinely zero-surprise migration. The phased plan let us keep production running while we modernised every site."
