Protecting networks from quantum-era threats

Quantum computing threatens the long-term security of encrypted data, requiring operators to rethink how they protect sensitive information that must remain secure for years or decades.

Securing communications in the quantum era demands more than traditional encryption approaches. Networks must protect data in motion against future decryption risks while maintaining confidence that secure services are operating as intended. Adtran addresses this challenge with a defense-in-depth approach that combines multi-layer, post-quantum-ready encryption across optical, Ethernet and IP environments with the capabilities required to operate and validate secure networks at scale.

In addition to cryptographic protection, Adtran extends security into the physical and operational layers of the network. Infrastructure monitoring and operational insights help teams assess the integrity of the transport environment supporting encrypted traffic, while assured operation supports security-sensitive and mission-critical use cases. Together, these capabilities enable operators to protect long-lived data, validate secure communications and maintain trusted network operation across service provider, enterprise, government and critical infrastructure environments.
