The German cybersecurity specialist Genua GmbH has introduced genuscreen Virtual – a powerful virtual firewall and VPN gateway designed for secure, scalable deployment in modern IT infrastructures. Developed in Germany and certified by the BSI, the solution combines flexibility with strict compliance for sensitive environments.

Genua GmbH, a cybersecurity company within the Bundesdruckerei Group, has released genuscreen Virtual: a virtualised combination of a high-assurance Layer 3 firewall and a VPN gateway, built for deployment in on-premises and cloud-based environments. Optimised for KVM and VMware ESXi 8.x, the virtual appliance delivers state-grade network security "Made in Germany" – and without backdoors.

A key feature is its GEO-IP filtering capability, which enables administrators to block traffic from specific geographic regions. This adds a strong layer of policy-based access control, especially relevant for public-sector networks, critical infrastructure (KRITIS), and defence-related applications.
 For secure mobile access, the solution integrates with genuconnect, Genua’s own VPN client, and supports additional clients such as the ECOS SecureBootStick SX and Apple Indigo setups for iPhones and iPads. This allows mixed environments of mobile and fixed endpoints to be managed securely and efficiently.

Temporary identities for high-assurance authentication

The built-in TI module enables temporary identities for secure server authentication – allowing for fast and reliable authentication of large numbers of VPN clients. The concept and technical implementation have been evaluated and accepted by Germany’s Federal Office for Information Security (BSI).
 The virtual firewall can also be used for site-to-site VPNs, working in conjunction with Genua’s hardware-based genubox remote access solution. It is managed centrally via the genucenter platform, enabling streamlined administration of mixed physical and virtual environments.

Same functionality, multiple formats

Genuscreen Virtual offers the same feature set as Genua’s hardware appliance, which runs the firewall software exclusively on dedicated, BSI-certified hardware – certified to Common Criteria EAL 4+, the highest applicable level for firewall systems. While the physical version is ideal for air-gapped or hardware-only environments, the virtual version is tailored for dynamic, containerised or cloud-based infrastructure.

“Genuscreen Virtual addresses the growing need for flexible, high-security network segmentation and access control across hybrid infrastructures,” the company says. Designed and manufactured entirely in Germany, the solution is part of Genua’s broader portfolio that includes secure remote access, VPNs, and internal network protection for both IT and OT environments.
