Qtonic Quantum Corp Launches QShield: Post-Quantum Protection for Links That Can't Wait. Zero Failures in 72 Hours

Software only, on the Linux hosts you already run. Available now through paid, operator-led engagements. A completed 72-hour endurance test recorded 4,107 successful checks and zero failures, and the evidence is published for anyone to inspect.

MIAMI, Sept. 17, 2026 /PRNewswire/ -- 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.

The launch on World Quantum Readiness Day follows a completed 72-hour endurance run with 4,107 successful periodic checks, zero recorded failed checks and zero recorded ping loss. The run log, the build hash and a verifier are published so buyers can check the result themselves. Request a demonstration at [email protected] or +1 (866) 4-QTONIC.

The clock is public

Intellectual property, research, financial records and government communications often need to remain confidential long after transmission. Adversaries can record encrypted traffic today and hold it for decryption by a sufficiently capable quantum computer. Every month of delay adds to what is exposed.

The deadlines are set. CNSA 2.0 requirements apply to new national security system acquisitions from January 1, 2027, 106 days from today, unless otherwise noted. Executive Order 14412 directs covered federal high-value assets and high-impact systems to move key establishment to post-quantum cryptography by December 31, 2030.

QShield addresses that exposure for traffic routed through its protected path. A full post-quantum migration takes years. QShield lets an organization protect its most sensitive connections now, on the infrastructure it already runs, while that migration proceeds.

"Information stolen today can remain valuable to an adversary for decades. Organizations need a practical way to begin protecting it now. QShield gives security leaders working software, a completed 72-hour endurance test and evidence they can examine. Bring us a connection that carries information you cannot afford to expose. We'll show you QShield operating, review the results with your team and define what deployment would require," said Col. Reginald M. Harris, U.S. Army (Ret.), Government Affairs, Qtonic Quantum Corp, and former Chief of Staff of U.S. Army Cyber Command.

Software-only protection. Endpoint-held private keys.

QShield runs a pure post-quantum asymmetric configuration. It combines ML-KEM-1024 (NIST FIPS 203) for key establishment, ML-DSA-87 (NIST FIPS 204) for endpoint authentication and AES-256-GCM for packet encryption. ML-KEM-1024 and ML-DSA-87 are the highest parameter sets in NIST's post-quantum standards and the parameters CNSA 2.0 specifies for national security systems.

Private keys remain on participating endpoints without dependence on a company-operated key-management service. The tested control channel negotiated ML-KEM-1024 for key establishment rather than a pre-shared-key mode. QShield's fail-closed design is intended to block protected traffic when required security conditions cannot be maintained.

The connections that cannot wait include data-center interconnects carrying financial records, research transfers between institutions, links between clinical systems, and server-to-server paths carrying regulated or mission information. Each engagement establishes the supported environment, routing requirements and acceptance criteria for the customer's use case.

The proof, published

The September 13 to 16 endurance run connected two Linux hosts in separate AWS availability zones in Oregon. Approximately every 63 seconds, the test checked connectivity, service status and a 64 KiB transfer with its SHA-256 recorded. All 4,107 checks reported success. At harvest, both daemon paths hashed to the identified build, and zero restarts were recorded. The 72-hour gate closed at 04:29 UTC on September 16. The operator left the overlay running.

The published evidence package includes the run log, build identification, checksums, a verifier and its output. The verifier passes 11 of 11 checks.

QShield engagements are available for purchase directly from Qtonic Quantum Corp. Enterprise buyers, government organizations and integration partners can request a demonstration and a scoped commercial proposal addressing their intended use, compatibility, delivery requirements, acceptance criteria and support terms.

Call +1 (866) 4-QTONIC or email [email protected] to see QShield working and request a proposal.

Evidence with every engagement. Each QShield engagement includes a documented test scope, a run log tied to the tested build by cryptographic hashes, state receipts and verification materials. With the customer's written approval, Qtonic Quantum Corp will publish an agreed evidence package, with identifying information included or withheld as authorized.

QShield is not represented as FIPS 140-3 validated or Government-authorized. Deployment suitability and any required approvals are determined for each environment.
