genuscreen by genua is a firewall and VPN appliance designed to protect data transfers and networks. It creates strongly encrypted Virtual Private Networks (VPN) for secure data communication over public networks, allowing the transmission of sensitive information. genuscreen precisely filters traffic at interfaces, allowing only explicitly desired connections while blocking all other requests. It meets high security requirements, evidenced by its approval for encrypted data transmission up to the confidentiality level VS-NfD and certification according to Common Criteria (CC) EAL 4+. genuscreen is scalable for installations with more than one system and is centrally manageable through the Central Management Station genucenter. It supports both IPsec and SSH-VPN, enabling secure communication between different networks without the need to align IP addresses. genuscreen also includes a Stateful Packet Filter that remembers communication history to enable comfortable communication at a high security level. It is available in various hardware variants to meet different performance requirements and can be bundled into powerful clusters to fulfill additional claims regarding bandwidth and availability. genuscreen is administered via its own web GUI and supports post-quantum cryptography with a quantum-resistant signature for future-proof software updates.
