IT/OT Security & Infrastructure
Increasing connectivity is making OT systems a prime target for cyberattacks. What used to be isolated is now closely connected to IT, the cloud, and partners—and is therefore significantly more vulnerable.
At the same time, requirements are increasing due to NIS2, KRITIS, and IEC 62443. Companies must expand their OT security in a structured and traceable manner.
gefeba provides practical OT security support—combining automation expertise, modern methods, and robust network architectures to create secure, future-proof production environments.
Skills
A thorough assessment of a company’s security level is the foundation for any effective security measure. gefeba analyzes industrial facilities where it matters most: in running processes, control systems, networks, servers, and HMI systems. Vulnerabilities and misconfigurations are clearly prioritized based on their actual impact on production, availability, and security.
This will provide you with a structured action plan that takes into account both immediate improvements and long-term optimizations. Together, we’ll ensure that your plant is set up for success well into the future.
Up-to-date systems are a critical factor in ensuring secure production processes. gefeba handles patch management for your OT environments: assessing relevance, risk-based testing, coordinated implementation, and audit-compliant documentation.
System downtime is consistently avoided: Whenever possible, updates are scheduled so that they can be seamlessly integrated into planned maintenance or operational processes. You benefit directly from a stable, audit-ready, and continuously maintained infrastructure.
Transparency regarding your own security status provides clarity and confidence in taking action. The comprehensive cybersecurity assessment covers networks, control systems, servers, remote access, user policies, and interfaces—in a practical manner and without unnecessary complexity.
The results are presented in a clear, structured, and easy-to-understand format. Instead of abstract theory, decision-makers receive concrete recommendations, prioritized actions, and a clear basis for decision-making regarding next steps.
Modern OT networks must be reliable, scalable, and secure, while also supporting operational activities at all times. gefeba develops architectures that meet these requirements: segmentation, redundancy, Industrial Ethernet, secure remote access, and tailored firewall concepts.
Thanks to our many years of experience as a Siemens Solution Partner, we create network structures that offer stability while also providing room for future digitization and automation projects. Companies gain a robust foundation on which they can build for the long term.
Your benefits:
- Protection of Critical Production Processes
- Reduced attack surface
- Future-Proof Network and System Architecture
- Technical Implementation from a Single Source
Targeted security testing of industrial systems under realistic attack conditions. The OT penetration test analyzes control systems, industrial networks, HMI/SCADA systems, remote access points, and interfaces to third-party systems.
gefeba combines OT-specific attack techniques with in-depth automation expertise—without the risk of unplanned system downtime. The result: precisely identified vulnerabilities, traceable attack paths, and a prioritized set of measures for maximum operational security.
gefeba helps operators and companies efficiently implement the regulatory requirements of NIS2, compliance with the KRITIS Framework Act, the Energy Industry Act (EnWG), industry-specific security standards, and ISO management systems.
This includes gap analyses, risk and asset assessments, the development of technical and organizational measures, and the establishment of lean ISMS structures (e.g., in accordance with ISO 27001). The focus is on pragmatic, audit-ready solutions that do not burden day-to-day operations.
