Public sector and defense
Securing critical infrastructure and sovereign networks
Public authorities, defense agencies and critical infrastructure operators face escalating cyber threats and growing pressure to protect sensitive, real-time communications. Whether transporting classified information or ensuring the availability of essential services, these networks must meet the highest standards for security, reliability and compliance. That’s why public sector organizations across Europe and beyond rely on Adva Network Security to safeguard their infrastructure. Built on decades of experience in optical transport and hardened Ethernet, our solutions are trusted where failure is not an option. They enable sovereign control, seamless interoperability and future-ready protection against both today’s attackers and tomorrow’s quantum threats.
Trusted encryption and quantum-safe innovation
Our ConnectGuard™ encryption technology secures data at every layer – optical and Ethernet – while meeting strict certification standards, including BSI approval for VS-NfD and NATO RESTRICTED use. From hardware-enforced key exchange to real-time traffic protection, our platforms are engineered to support mission-critical operations with ultra-low latency and zero compromise. We work closely with national agencies, defense partners and EU-funded initiatives like DE-QOR and IPCEI-CIS to shape the next generation of secure networking. With integrated support for post-quantum cryptography and quantum key distribution, our technology is designed to defend against emerging quantum-era risks. Combined with services spanning security operations center-as-a-service, penetration testing and long-term lifecycle support, we provide a complete foundation for cyber-resilient public networks.
