Secure Production in the Era of Industry 4.0
The digital transformation of industrial operations offers immense opportunities — but it also introduces new risks.
As production systems, control technologies, and logistics networks become increasingly interconnected, Operational Technology (OT) is emerging as a prime target for cyber threats.
msg Plaut helps organizations minimize these risks sustainably.
As an experienced partner in Cybersecurity, Compliance, and OT Engineering, we combine regulatory expertise (e.g. IEC 62443, NIS2) with technical implementation excellence.
Our goal: resilient, secure, and future-ready production environments that ensure stability, efficiency, and compliance.

Our Core Competencies in OT Security
Cybersecurity for OT Environments – Protecting Critical Systems
We secure your industrial networks, control systems (e.g. SCADA, PLC), and production equipment through multi-layered security architectures, tailored to your infrastructure and operational realities.
By implementing Zero Trust principles, network segmentation, and intrusion-resilient designs, we establish a dynamic security culture that continuously adapts to evolving threats.
Our Services at a Glance:
- Development and implementation of OT security strategies
- Establishment and operation of Cyber Security Management Systems (CSMS)
- Implementation of Zero Trust network architectures
- Protection of ICS, SCADA, and PLC environments
- OT-specific security monitoring and incident response
- Security audits and technical risk analyses
Result: A sustainable, standards-compliant security foundation for industrial control systems — robust, scalable, and future-proof.
Assessments & Certifications – Security with System and Proof
msg Plaut guides you through preparation, execution, and follow-up of OT security assessments in line with international standards.
We identify vulnerabilities, conduct gap analyses, and develop action plans for certifications according to IEC 62443, NIS2, and ISO 27001.
Our Assessment Services:
- Security maturity assessments and gap analyses
- Preparation for audits and certifications (IEC 62443, ISO 27001, NIS2)
- Development of security policies and process manuals
- Creation of testing and verification strategies for OT systems
- Continuous monitoring and compliance performance reporting
Outcome: Certification readiness and lasting compliance — achieved efficiently, transparently, and without interrupting operations.
Process Development & Optimization – Security by Integration, Not Addition
Cybersecurity isn’t an add-on — it’s a core element of operational excellence.
We integrate security requirements directly into your engineering and maintenance processes — from system architecture to lifecycle management.
Using Model-Based Systems Engineering (MBSE) and System-Theoretic Process Analysis (STPA), we close security gaps proactively and ensure process resilience.
Our Process Services:
- Implementation of Security-by-Design principles in OT processes
- Integration of security policies into engineering workflows
- Establishment of governance frameworks for OT security
- Process analysis and optimization based on IEC 62443 and NIS2
- Monitoring and continuous improvement via PDCA cycles
Result: Efficient, audit-ready processes that combine security, productivity, and regulatory compliance.
Training & Qualification – Knowledge as the Strongest Defense
Human behavior remains one of the most critical factors in cybersecurity.
We strengthen your teams’ awareness and expertise through hands-on training, simulations, and TÜV-certified qualification programs tailored to industrial environments.
Training Portfolio:
- Awareness training for production and maintenance personnel
- Technical training on IEC 62443, NIS2, and OT security principles
- In-house and TÜV-certified training programs
- Incident response simulations and red team exercises
- Coaching for security officers and operations managers
Outcome: A lived security culture in production — with employees who detect risks early, respond effectively, and take ownership of security.
