Quantum cyber risk intelligence provider Qtonic Quantum Corp has launched QShield, a software-based post-quantum cryptography (PQC) packet runtime engineered to protect active network connections between Linux endpoints. Available through operator-led engagements, the SAFE/29 runtime establishes encrypted overlay tunnels using NIST-standardized algorithms to defend sensitive data transit against “Harvest Now, Decrypt Later” (HNDL) exploitation without requiring dedicated hardware appliances or pre-shared key infrastructure.
Operating entirely at the host layer, QShield integrates a pure post-quantum asymmetric security stack: ML-KEM-1024 (NIST FIPS 203) for quantum-resistant key exchange, ML-DSA-87 (NIST FIPS 204) for endpoint digital authentication, and AES-256-GCM for symmetric payload encryption. The parameter configurations reflect the highest security levels specified under NIST guidelines and align with upcoming federal mandates—including CNSA 2.0 requirements for national security system acquisitions beginning January 1, 2027, and Executive Order 14412 directives for high-value federal assets through 2030.

To validate runtime stability prior to release, Qtonic Quantum published a cryptographically verified evidence bundle following a 72-hour endurance test conducted between AWS availability zones in Oregon. The test logged 4,107 consecutive checks (executing 64 KiB data transfers roughly every 63 seconds) with zero daemon restarts or packet losses recorded. Headquartered in Miami under Government Affairs lead Col. Reginald M. Harris (U.S. Army Ret.), Qtonic Quantum targets deployment across data-center interconnects, high-value financial data channels, and research transfers while enterprise-wide PQC migration continues.
