Infrastructure Security

Infrastructures with security-related functions are subject to rapid change due to evolving business processes, new technologies, and increasing corporate requirements. Developments such as virtualization, cloud services, and the growing interconnectivity of industrial systems are leading to increasing complexity in modern IT and OT networks.

Network security is therefore an ongoing process within a secure infrastructure. Systems, networks, and communication interfaces must be continuously reviewed and adapted to detect known and new vulnerabilities early on and minimize potential attack vectors.

By analyzing network architectures, security mechanisms, and communication paths, risks can be identified and appropriate protective measures derived. This process takes into account both traditional IT infrastructures and industrial OT systems such as production facilities, control systems, and IoT components.

Our Network Security Services

• Analysis of IT and OT networks for security risks and misconfigurations
• Identification of known and unknown vulnerabilities (automated and manual)
• Assessment of existing security mechanisms and network architectures
• Preparation of detailed security reports and recommendations for action
• Support in the implementation of security measures
• Retesting and verification of the effectiveness of implemented security measures

Network Gateways and Segmentation

Network gateways represent particularly critical points within an infrastructure. These include, for example, internet connections, links between company locations, or interfaces between IT and OT networks. Without clear separation and controlled communication rules, attacks can quickly spread from one network segment to other systems.

Appropriate measures such as network segmentation, firewalls, access controls, or intrusion detection and prevention systems can significantly reduce these risks and effectively protect sensitive systems.
