Securing critical infrastructure amidst geopolitical pressure, cloud transformation and quantum-resistant cryptography

The requirements for highly secure digital infrastructure are undergoing fundamental change. Geopolitical tensions, hybrid threats and increasing dependence on digital platforms are shifting the focus of many organisations in the defence sector and in the classified industry towards a central issue: digital sovereignty. At this year’s AFCEA Trade Show 2026, genua GmbH is positioning itself with a clear guiding principle: “Mission Critical Connectivity. Secure. Sovereign. Mobile.”

The IT security specialist, part of the Bundesdruckerei Group, will be showcasing solutions for the protection of mission-critical and highly sensitive IT environments at the World Conference Center Bonn. The focus will be on Security-by-Design approaches, BSI-approved security solutions and virtualised security architectures for hybrid infrastructures.

Security architectures for emergencies

The current security landscape is also changing the requirements for government and industrial communication infrastructures. Traditional network security is no longer sufficient in highly critical environments. What is required are resilient, scalable and sovereign security architectures that remain operational even under exceptional operating conditions.

This is precisely where genua comes in. The company focuses in particular on organisations with high regulatory and security-related requirements – including the German Armed Forces, government agencies, KRITIS operators and industries subject to secrecy regulations. The solutions presented are generally approved for at least VS-NfD, NATO RESTRICTED or EU RESTRICTED.

It is clear that the discussion surrounding digital sovereignty is no longer an abstract political debate, but is increasingly becoming a core operational requirement of modern security architectures. Particularly in security-critical areas, the origin, controllability and trustworthiness of IT systems are coming under greater scrutiny.

Quantum-resistant encryption and high-speed VPN

A key exhibit at the trade fair is the new high-speed VPN gateway “genuline”. The solution connects sites in compliance with VS-NfD standards at transmission rates of up to 100 Gbit/s in full-duplex operation. Technologically, genua relies on FPGA-based hardware acceleration to combine high data rates with quantum-resistant Layer 3 encryption.

In doing so, the company is addressing a strategically relevant future field: the transition to quantum-secure cryptographic approaches. Whilst quantum computing is not yet widely available, concerns are already growing in security-critical sectors about “harvest now, decrypt later” scenarios, in which encrypted data could be stored long-term and later decrypted using powerful quantum computers.

The integration of quantum-resistant encryption methods therefore demonstrates how strongly security strategies are increasingly geared towards long-term resilience.

Mobile VS-NfD workstations as a security factor

In parallel, mobile and secure access to sensitive information is also gaining in importance. Mobile working capability is now regarded as a strategic factor for leadership, operational coordination and business continuity.

genua presents several BSI-approved solutions for this purpose – ranging from the VPN software client “genuconnect” to the “genusecure Suite”, which combines hard disk encryption, smart card middleware and secure communication mechanisms within a VS-NfD-compliant environment. The portfolio is complemented by the complete solution “HP Sure Station”, which combines security software with specially secured end devices.

This approach highlights a trend that is increasingly shaping the entire security market: security is no longer viewed in isolation at the network level, but as an integrated end-to-end architecture from the end device right through to hybrid cloud infrastructures.

Data diodes and network segmentation for highly secure environments

Particularly in the field of critical infrastructure, the physical and logical separation of sensitive networks remains a key security mechanism. To this end, genua is showcasing, among other things, the “vs-diode”, which enables high-performance one-way data transfer in networks with security classifications up to GEHEIM or NATO SECRET.

Data diodes are considered essential particularly where a controlled flow of information without a return channel is required – for example, in military environments, industrial control networks or highly critical control centre infrastructures.

This is complemented by solutions for highly secure network segmentation. The “enoughate” firewall is classified as “highly resistant” by the BSI and combines application-level gateway and packet filtering technologies. With “enoughate Virtual”, genua also addresses dynamic and virtualised deployment scenarios.

According to the company, the virtualised version is the only virtualised firewall with VS-NfD certification. This underscores an important trend in the market: Even highly critical security architectures are increasingly moving towards software-defined and virtualised operating models.

Hybrid cloud models: balancing resilience and autonomy

In addition to traditional security solutions, genua is also addressing the growing importance of hybrid cloud architectures at AFCEA. Public authorities and security-critical organisations in particular are increasingly faced with the challenge of combining cloud flexibility with regulatory control and digital autonomy.

In the presentation “Trust, but Verify: Hybrid Clouds for Resilience and Strategic Autonomy”, genua expert Arnold Krille explains how stable and controllable operating models can be realised even under crisis conditions through appropriate technology decisions and resilient system designs.

The debate surrounding hybrid clouds is increasingly becoming a question of strategic agency. For the more organisations become dependent on external platform providers, the more important controllable security architectures, traceable data flows and sovereign operating models become.

Security ecosystem of the Bundesdruckerei Group

The trade fair presence also demonstrates the strategic integration within the Bundesdruckerei Group. Alongside genua, D-Trust and xecuro are also represented. Whilst D-Trust presents VS-NfD-compliant file sharing, xecuro focuses on highly secure communication solutions for sensitive government and public authority communications.

In addition, long-standing partner ECOS Technology is showcasing its Secure Boot Stick.

This makes it clear that security requirements are increasingly evolving into integrated platform and ecosystem approaches. What is needed is no longer just individual products, but interoperable security architectures that combine communication, access protection, encryption, segmentation and cloud security.

Conclusion: Resilience is becoming a core requirement of modern security architectures

genua’s presentation at AFCEA 2026 highlights a key development in the security market: digital sovereignty is evolving from a political buzzword into a core operational competence of modern organisations.

In the process, requirements are shifting significantly – away from isolated protective measures towards resilient, highly integrated security architectures that combine mobility, cloud usage, quantum-resistant encryption and sovereign infrastructure control.

Particularly in times of increasing geopolitical uncertainty, IT security is thus becoming an ever more crucial strategic prerequisite for operational capability, readiness and institutional resilience.
