Fundamental Paradigm Shift
Why Corporate IT Security Fails on the Manufacturing Shop Floor
Industrial automation hardware and control cabinets operate under strict physical and temporal realities radically different from office and cloud environments.
Operational Priority
Data confidentiality and cloud database protection.
Absolute availability (24/7 uptime) and physical safety of operators and machinery.
Updates & Patching
Automated patch cycles and regular reboots scheduled after office hours.
An unscheduled reboot ruins production batches or misaligns robotic cells.
Network Determinism
Tolerance for jitter and hundreds of milliseconds of cloud latency.
Real-time deterministic communications in microseconds (Profinet IRT, EtherCAT, Profisafe).
Asset Lifecycles
Hardware servers and laptops replaced every 3 to 5 years.
Industrial control cabinets and process lines operating 15 to 25+ years.
Protective Engineering
The 4 Pillars of Shop-Floor Cybersecurity
We guarantee uninterrupted machine availability, process parameter integrity, and operator physical safety.
Network Segmentation (Purdue Model / IEC 62443)
Strict isolation between the corporate network (IT) and the plant control network (OT) via industrial firewalls and dedicated VLANs, preventing an office breach from reaching production PLCs.
- Zones and conduits segmentation (IEC 62443-3-3)
- Granular filtering of industrial protocols (Profinet, Modbus TCP, OPC UA)
- Perimeter containment of malware, worms and corporate ransomware
Secure Remote Assistance via Secomea
End-to-end encrypted remote access for technical support and SAT diagnostics on production lines and robotic cells, without opening incoming ports on client routers and with multi-factor authentication.
- TLS/AES encrypted VPN tunnels with zero open inbound ports
- Full client-side access control (hardware key or software authorization)
- Auditable connection logging and session traceability
Machine Control System Safety (EU Regulation 2023/1230)
Compliance with the new European Machinery Regulation: logical and physical protection of machine control circuits against tampering or cyber intrusions that could alter safety functions.
- Conformity with EN ISO 13849-1 and EN 60204-1
- Protection of safety PLCs and failsafe fieldbuses (Profisafe)
- Integrated risk assessment: functional safety + cybersecurity
PLC, HMI & SCADA Hardening
Restrictive device configuration: closing unused ports on Siemens and Omron PLCs, disabling unencrypted web servers, and implementing engineering password hierarchies.
- Closing vulnerable services and protocols (HTTP, Telnet, SNMP v1)
- Memory read/write protection on industrial controllers
- Project versioning and automated backup policies
Defensive Architecture
Shop-Floor Level Segmentation (Purdue Model)
Standardized perimeter containment according to IEC 62443-3-3: a corporate office security incident must never reach the manufacturing line.
Enterprise Network (IT) & Cloud
ERP systems (SAP, Navision), corporate email, servers, and outbound Internet access.
Industrial DMZ & Secomea SiteManager Gateways
Strict bidirectional filtering: shop-floor controllers are never directly visible or addressable from the Internet.
Manufacturing Operations & Supervision (SCADA / MES)
Line SCADA servers, local SQL process historians, and operator monitoring terminals.
Production Lines, PLCs & KUKA Robots
Siemens S7-1500 / Omron controllers, HMI touchscreen panels, variable speed drives, and Failsafe buses.
Why We Embed Secomea SiteManager in Our Control Cabinets
To provide instant technical support and rapid troubleshooting without jeopardizing client network integrity or exposing external vulnerabilities.
Zero Open Inbound Ports
The SiteManager gateway establishes an outbound connection to the central GateManager. No firewall reconfiguration or static public IPs are required on the client network.
Customer-Controlled Access
Plant staff retain total control over when remote assistance is allowed, using a physical key switch on the cabinet or time-bounded software authorizations.
BSI & IEC 62443 Certified
Certified to the highest international security standards, ensuring that technical support connections pass stringent corporate security audits.
Multi-Vendor Compatibility
Seamless remote engineering for Siemens TIA Portal, Omron Sysmac Studio, Schneider EcoStruxure, KUKA WorkVisual, and Rockwell Studio 5000.
European Legal Requirements
Regulatory Framework for Connected Industry
European directives mandate that cybersecurity is no longer just an IT matter, but an integral requirement for machine control circuits and production equipment.
NIS2 Directive
Mandatory European legal framework for critical sectors (agri-food, water, energy, and manufacturing). Mandates cybersecurity risk management in OT networks and supply chains, alongside strict incident notification protocols.
- Risk management across shop-floor networks
- Supply chain cybersecurity for machinery builders
- Operational business continuity and recovery plans
UNE-EN IEC 62443
The global benchmark standard for industrial automation cybersecurity. Defines the Zones and Conduits architecture and establishes required Security Levels (SL) to protect critical operational infrastructure.
- Purdue reference model for level segmentation
- Controlled security zones and monitored conduits
- Integrated technical system and component requirements
Machinery Regulation
Replaces Directive 2006/42/EC and makes it legally mandatory that machine control circuits are protected against deliberate or accidental network-based tampering or external device attacks.
- Protection of machine control circuits against cyber threats
- Logging of configuration changes and safety parameter edits
- Mandatory requirement in the CE technical construction file
Cyber Resilience Act
European legislation establishing cybersecurity-by-design standards across the entire product lifecycle for connected industrial hardware and software, including continuous vulnerability management.
- Cybersecurity-by-design from early engineering stages
- Secure firmware lifecycle and automated patch management
- Assessment of third-party integrated software components

Technical Clarifications
Frequently Asked Questions on OT Cybersecurity
Q. Does implementing OT cybersecurity require halting ongoing production?
No. Our network segmentation and gateway deployments are designed to execute without interrupting production schedules. Audits and traffic mapping are performed passively (using SPAN port mirroring), and physical hardware installations are scheduled during planned maintenance windows.
Q. Why cannot corporate IT security tools be applied directly to plant PLCs?
Corporate IT prioritizes confidentiality and accepts frequent reboots for security updates. In industrial OT, absolute 24/7 uptime and operator physical safety are paramount: an unscheduled reboot or network packet delay on fieldbuses can trigger emergency stops, ruined batches, or mechanical collisions.
Q. How does Secomea ensure that unauthorized actors cannot reach machines?
Secomea communicates exclusively via outbound encrypted tunnels (TLS/AES-256) authenticated by x.509 certificates and two-factor authentication (MFA). The cabinet SiteManager has zero open listening ports facing the internet, eliminating external brute force or scanning vectors.
Q. What does the new EU Machinery Regulation 2023/1230 require regarding cybersecurity?
Starting from its mandatory enforcement date in January 2027, all industrial machinery placed on the EU market must incorporate technical measures ensuring that external network connections cannot manipulate or disrupt safety-critical control functions.
