KRITIS

Secure. Resilient. Future-oriented – solutions for critical infrastructures.

Critical infrastructures are essential for the functioning of modern societies and are the focus of increasing security requirements. For over 140 years, STUV has been supporting operators in this area with innovative solutions that are specially tailored to the needs of KRITIS sectors. Our PYLOCX® systems set new standards in access control and meet the most stringent standards, including the European Union's CER Directive and the KRITIS umbrella law.

CHALLENGE

Challenges in the KRITIS sector

Securing critical infrastructure is one of the most demanding tasks in the field of security technology. Operators must ensure both physical protection and cyber security in order to protect supply systems such as energy, water, telecommunications and banking. Legal requirements such as the CER Directive and the KRITIS umbrella law require resilient and crisis-proof systems that continue to function reliably even in the event of power or network failures.

SOLUTIONS

Our customised solutions

Our PYLOCX® technology has been specially developed to meet the specific requirements of critical infrastructure sectors. With battery-free, robust locking components and a secure, GDPR-compliant access system with one-time codes, we offer the ideal combination of physical protection and digital control. Our products are BSI, VdS and CER compliant and guarantee maximum resistance to external influences such as heat, cold, vandalism or network failures.

The integration of PYLOCX® with PYSUITE® software also provides seamless monitoring and documentation, while PYBOX® transport boxes ensure the safe transport of sensitive components such as smart meter gateways.
