Projects
OPNESAS
The GSMA NESAS scheme enables security assurance of 5G network components. The OPNESAS project aims to operationalize the NESAS scheme for equipment vendors, network operators, certification authorities and test labs. We are focusing on seamless integration of the scheme into existing deployment infrastructures to achieve widespread adoption of the scheme.
Radix Security
5G network technology is incredibly complex, and with the necessary security standards this complexity is even increased. At Radix Security we eliminate the complexity of 5G and we make 5G security accessible instead by providing the proper tools, training and research. We want to empower our customers to create a secure mobile network for the current generation of 5G, 6G and beyond.
