Vendor-agnostic adaptation
We do not replace SCADA/PLC/DCS in production: we layer on top of the existing infrastructure, preserving the investments you have made, with visibility, segmentation and passive detection.
Cybersécurité pour machines industrielles et réseaux OT.
Usines de production, SCADA, PLC et réseaux de contrôle sont dans le viseur. Fortgale protège les infrastructures OT en s'adaptant au stack existant — sans arrêter la production.

Why Fortgale for OT
Adapts to your existing stack. It does not replace it.
OT is not IT. Decade-long lifecycles, availability constraints, proprietary protocols. Our approach is non-invasive by design.
02 ·
Strategic partnership
For new plants or OT digitalisation, we support the customer in selecting market technologies and designing secure architecture. Compatible with Siemens, Rockwell, Schneider, ABB.
03 ·
Zero-impact passive monitoring
Only passive monitoring of OT traffic (Modbus, Profinet, DNP3, OPC-UA): no active scanning that could halt a PLC or interfere with critical processes.
Proof · the OT risk numbers
Four data points industry cannot ignore.

Our approach
Two protection models, one objective: security that works in the real environment.
There is no single way to protect an industrial company. Two models depending on the starting point.
Model 01 · Adaptation
We integrate into the existing stack
Passive monitoring, integration with existing SCADA, automatic asset inventory, detection on Modbus/Profinet/DNP3, IT/OT segmentation without replacements, compensating controls on legacy systems. Onboarding in 4-6 weeks.
Model 02 · Partnership
We become the strategic cyber partner
Vendor-agnostic evaluation, secure industrial architecture design (segmentation, OT DMZ), deployment support, remote-access policy, IT/OT team training. Ideal for new plants or digitalisation.
The pillars of OT protection
Six modules that protect the entire industrial infrastructure.
From asset discovery to NIS2 compliance, under the governance of the Fortgale European SOC.
01
Asset Discovery & OT visibility
Passive inventory of PLC, HMI, SCADA, DCS, sensors and IIoT. Continuously updated asset map, criticality classification, identification of unlisted systems.
02
Passive network monitoring
Automatic learning of the traffic baseline for Modbus/Profinet/DNP3/OPC-UA, deviation detection without active scanning. Zero operational impact.
03
OT incident detection & response
The Fortgale European SOC extends MDR to the OT network: triage in <15 min, IT/OT-aware runbooks, orchestrated containment without halting critical processes.
04
Risk Assessment & vulnerability
OT-aware contextual evaluation of vulnerabilities (CVEs not always patchable), compensating controls, prioritisation by operational impact.
05
IEC 62443 & NIS2 compliance
Gap assessment against IEC 62443-3-3, NIS2, NIST CSF, remediation plan, audit-ready documentation, support for CSIRT notification sous 72 heures.
06
OT training & awareness
Dedicated training for IT/OT teams, automation suppliers, maintenance crews. Secure remote access procedures, jump server, MFA everywhere.

Everything to know before talking to our analysts.
What is the difference between IT and OT security?
IT protects information systems (servers, PCs, cloud, data). OT Security protects systems that control physical processes (machines, SCADA, PLC, DCS): an incident halts production or puts people at risk. It requires specific approaches, tools and competences.
Does Fortgale need to replace control systems?
No. We adapt to the existing setup in a non-invasive way: visibility, segmentation and detection layered on top of the present infrastructure. For new projects, vendor-agnostic strategic partnership.
Can legacy OT systems be protected without upgrades?
Yes. Compensating approach: network segmentation to isolate vulnerable systems, passive monitoring, perimeter controls. Legacy devices are protected without touching them.
Does NIS2 apply to manufacturing with OT?
NIS2 transposition across EU member states covers energy, transport, water, food and high-criticality manufacturing. OT companies running essential services fall under NIS2 obligations with specific ICS requirements and national CSIRT notification sous 72 heures.
What is IT/OT convergence and why does it raise risk?
Integration between corporate IT and industrial OT, enabled by IIoT, remote access and digitalisation, exposes OT to IT attack vectors: ransomware on the corporate network can propagate to SCADA; unprotected remote access to HMIs is a direct doorway to plants.
