Qtonic Quantum Launches QShield for Post-Quantum Network Protection

Insider Brief

• Qtonic Quantum has launched QShield, a software-based post-quantum protection system for securing traffic between compatible Linux endpoints.
• QShield combines ML-KEM-1024, ML-DSA-87 and AES-256-GCM, with private keys remaining on participating endpoints and protected traffic blocked when required security conditions are not met.
• Qtonic Quantum reported 4,107 successful checks with zero failed checks and zero recorded packet loss during a 72-hour endurance test conducted across two AWS availability zones.

PRESS RELEASE — Qtonic Quantum Corp today launched QShield, its SAFE/29 packet runtime, and opened paid, scoped, operator-led engagements to enterprise and government organizations, available now. QShield puts post-quantum encryption on a sensitive network connection using software alone, so an organization can protect what matters most today instead of waiting for a migration that will take years.

QShield protects traffic routed between compatible Linux endpoints using post-quantum key establishment and authentication, alongside AES-256-GCM packet encryption. It is delivered and operated by Qtonic Quantum Corp. Engagements begin on company-operated hosts and are scoped to the customer’s environment, without dedicated encryption appliances at the participating endpoints.
