PMRExpo 2025: IHSE, Knuerr, and Voxtronic Demo End-to-End Security Solutions

Under the motto “From signal to communication: security without gaps,” the three European technology providers IHSE, Knuerr, and Voxtronic will jointly present at PMRExpo 2025 in Cologne. Their integrated approach demonstrates how combining hardware, infrastructure, and communication solutions ensures comprehensive protection for critical systems.

Joint mission: Holistic security instead of isolated solutions

Increasing digitalization and legal requirements such as NIS-2 and the KRITIS umbrella law call for a rethink in security architecture. Operators of critical infrastructures must take a holistic view of their systems: only a consistent concept across all levels of communication, control, and infrastructure offers true resilience, redundancy, and reliability.

The joint appearance of IHSE, Knuerr, and Voxtronic shows how specialized European technologies interlock to ensure maximum security and availability.

IHSE: Secure IT and server infrastructure

For decades, IHSE has been synonymous with certified KVM technology made in Germany. IHSE’s Common Criteria-certified components, hardware access protection, and true physical isolation (“air gap”) safeguard critical control logic in control centers.

The KVM systems physically separate data and management networks from each other, preventing unauthorized access, malware infections, and network attacks. The result: maximum integrity and availability of core systems. IHSE thus creates the basis for secure, highly available infrastructures in mission-critical areas such as defense, transportation, energy, and government agencies.

Knuerr: Secure control rooms and ergonomic workplace solutions

As a specialist in control room and control center solutions, Knuerr GmbH provides the physical foundation for secure operations, combining modular, ergonomic desk systems with integrated workplace technology. With modular, ergonomic control center desks and integrated workplace solutions, Knuerr creates an environment that ensures efficiency, ergonomics, and operational safety.

The integration of secure hardware components, such as IHSE’s KVM systems, enables a robust, fail-safe control center architecture. The focus is on people: ergonomics, intuitive usability, and a clearly organized workspace are key to operational security. Knürr combines technology, design, and functionality into a control center concept that meets the high demands of critical infrastructures.

Voxtronic: Secure communication

Austria-based Voxtronic is a leading provider of mission-critical communication systems. With its Conex™ communication platform, the company ensures that voice and data communication and documentation remain encrypted, redundant, and fail-safe even under extreme conditions. Communication is the backbone of every safety-critical operation. Failures are simply not an option. Voxtronic therefore provides KRITIS solutions with secure interfaces and protocols that guarantee availability and authenticity at all times.

Security without gaps — Made in Europe

The joint appearance at PMRExpo underscores a shared belief: true security can only be achieved when every layer from signal transmission to communication works seamlessly together. Together, IHSE, Knuerr, and Voxtronic represent interoperable, trustworthy European expertise delivering resilience, recoverability, and compliance across critical infrastructures.
