Qryptonic released the Quantum Exposure Index, an independent analysis powered by QScout26, finding that zero analyzed enterprise endpoints are prepared for post-quantum cryptography. The study shows universal reliance on quantum-vulnerable key exchange, leaving encrypted data transmitted today exposed to future harvest-now-decrypt-later attacks.

Miami, FL January 19, 2026 --(PR.com)-- Quantum Exposure Index, powered by QScout26, shows widespread reliance on cryptography vulnerable to harvest-now-decrypt-later attacks.

Qryptonic today released the Quantum Exposure Index, an independent analysis of publicly observable enterprise cryptographic posture and its exposure to future quantum decryption. The analysis was conducted using QScout26, Qryptonic’s quantum-readiness assessment platform.

Using QScout26, Qryptonic analyzed 528 publicly reachable enterprise endpoints, comprising 351 reachable domains from the Tranco Top 500 and 192 reachable endpoints across five sectors: Finance, Healthcare, Government, Energy, and Retail. The analysis found that zero observed endpoints have deployed post-quantum cryptography or hybrid post-quantum key exchange, and that all observed endpoints rely on key-exchange mechanisms vulnerable to future quantum attacks.

“What this data makes clear is that modern cryptography is not the same as quantum-safe cryptography,” said Mark Schrick, Vice ...
