- VPN Appliance genuscreen and VPN Client genuconnect for secure data communication infrastructure with BSI approval for German classification level “Restricted”
- Quantum-resistant VPN protects against threat of communication decryption by quantum computers
- Security "Made in Germany" strengthens digital sovereignty of public authorities, critical infrastructure operators and other security-sensitive companies
Kirchheim (Germany), September 25, 2025 – With the VPN Gateway genuscreen and VPN Client genuconnect, the security expert genua from Kirchheim near Munich, a company of the Bundesdruckerei Group, provides a fully quantum-resistant VPN solution which is approved by the German Federal Office for Information Security (BSI) up to German classification level "Restricted".
This allows public authorities, operators of critical infrastructures and companies with an obligation to maintain secrecy to protect their site networking and the remote connection of employees without fear of their communications and data being decrypted by tomorrow's quantum computers.
EU Demands Changeover to Quantum-Resistant Security
According to the EU digital strategy, all member states are required to start the changeover to quantum-resistant cryptography (post-quantum cryptography, PQC) by the end of 2026. Critical infrastructures must be converted to PQC as quickly as possible and no later than the end of 2030.
This is because the development of quantum computing is advancing at a rapid pace. The BSI anticipates that risk managers should assume a significant likelihood of quantum attackers from the beginning to middle of the 2030s.
VPN: Cornerstone of Every Post-Quantum Strategy
Companies should already be safeguarding their data now using quantum-resistant encryption in order to protect themselves against "store now, decrypt later" attacks. In such attacks, the actor – e.g., a state-sponsored attacker – exfiltrates encrypted data sets in order to decrypt them as soon as the processing power of future quantum computers is sufficient to do so.
The critical point here is the key exchange during asymmetrical encryption of the data transfer via virtual private network (VPN). Attackers with access to quantum computers could in future compromise the key exchange as well as encrypted software updates of the VPN components. The changeover to a quantum-resistant VPN should therefore be an integral part of every post-quantum strategy.
Important Criterion: BSI Approval
In public authority, critical infrastructure and confidentiality environments, a VPN solution not only needs to be quantum-resistant but must also have BSI approval up to German classification level "Restricted". With the VPN Appliance genuscreen and the VPN Software Client genuconnect, genua offers a complete VPN infrastructure which meets both conditions.
"BSI approval to German classification level "Restricted" confirms the quality of our VPN solution," says Matthias Ochs, Managing Director of genua. “It allows security-sensitive organizations to achieve an extremely high level of protection for site networking and flexible working, e.g., on the move or when working from home. At the same time, thanks to a fully 'made in Germany' security infrastructure, they are independent of foreign equipment suppliers and thus strengthen our digital sovereignty.”
"genua has been addressing the quantum issue for around 15 years now," adds Stefan-Lukas Gazdag, IT security researcher and PQC expert at genua. “We already received approval for quantum-resistant software updates for our VPN Appliance genuscreen in 2017. This was followed last year with approval for a VPN with quantum-resistant key exchange. We are actively pursuing the topic, coordinating with the responsible authorities and devising migration steps. As a result, genua is one of the prime addresses for PQC migration.”
BSI approval is an important quality criterion that provides guidance for companies and public authorities when selecting highly secure IT security components. In addition, genuscreen fulfills the requirements of the international classifications NATO RESTRICTED and RESTREINT UE/EU RESTRICTED.
At the leading IT security trade fair it-sa in Nuremberg (Germany), interested parties can find out more about the quantum-resistant, BSI-approved VPN from genua (Hall 9, Booth 424).
