genubox by genua provides secure remote access solutions for businesses and service providers. It can be installed on industrial robots, wind turbines, or in server rooms, allowing manufacturers or service providers to monitor and manage systems remotely. In maintenance cases, genubox ensures security by establishing an encrypted connection for data transmission and restricting external access to the managed system through its firewall function, making other sensitive network areas inaccessible via the maintenance access. genubox operates on the highly secure OpenBSD operating system, which has been further hardened. It meets all requirements of the Federal Office for Information Security (BSI) for cybersecurity in the industrial environment during remote maintenance. genubox supports Zero-Trust concepts, ensuring that trust in the overall network's security is replaced by trust in the security of specific communication endpoints. The remote maintenance solution is fully set up by simply connecting the pre-configured solution to the network, allowing access to the rendezvous server from the network. genubox also supports post-quantum cryptography, ensuring trustworthy product updates now and in the future. The infrastructure components of genubox are available as hardware and virtualized appliances, including support for Azure Cloud.
