Cyber defense engineered for the quantum era.
Cryptographically-relevant quantum computers will eventually break the public-key encryption that today’s most sensitive data depends on. SIMAQ designs and deploys the quantum-safe communication infrastructure, fibre and satellite Quantum Key Distribution, optical ground stations, and post-quantum cryptography, that lets Saudi Arabia’s governments, enterprises and national networks get ahead of that threat.
“Harvest now, decrypt later” is already a live threat model.
Adversaries can record encrypted traffic today and decrypt it once a sufficiently powerful quantum computer exists. For data that must stay confidential for years or decades, that risk exists now. NIST finalized the first three federal post-quantum cryptography standards in August 2024, and national cybersecurity authorities worldwide are moving migration planning onto near-term roadmaps.
Store-now, decrypt-later
Encrypted data intercepted today can be decrypted retroactively once large-scale quantum computers mature.
NIST FIPS 203 / 204 / 205
ML-KEM, ML-DSA and SLH-DSA are now the U.S. federal standards for quantum-resistant cryptography.
Defense in depth
QKD delivers information-theoretically secure key exchange; PQC hardens classical systems at scale. SIMAQ deploys both.
