What is quantum cybersecurity?

Quantum cybersecurity is the practice of defending data, systems and decisions against threats that exploit (or anticipate) quantum-class capability — most importantly, harvest-now-decrypt-later attacks on long-lived encrypted data, and the use of quantum-inspired techniques to detect attacker behaviour that classical tools miss.

In more depth

It has two halves. The defensive half is post-quantum cryptography (PQC): migrating to algorithms standardised by NIST (FIPS 203/204/205) so today's encrypted traffic stays confidential once quantum computers can break RSA and ECC. The offensive-defence half is using quantum-inspired analytics to spot correlated weak signals across telemetry — the patterns single-channel anomaly detectors miss.

Both halves matter because long-lived data (bank records, health records, defence material) is already at risk: an attacker only has to copy ciphertext today and wait.

How JAQL approaches this

JAQL runs the five-phase PQC migration inside the client's own systems and ships StressTrace for quantum-inspired SOC analytics. See /post-quantum-security and /products/stresstrace/.
