Post-Quantum Cryptography
Protect today’s data from tomorrow’s computers.
Adversaries are already collecting encrypted data to decrypt once quantum computers mature. XQ protects it now, with NIST-standardized post-quantum algorithms, including Dilithium, on a crypto-agile platform that adopts new standards without replacing your infrastructure.

Safe from harvest-now, decrypt-later
Data captured today stays protected when quantum attacks become practical.
No hardware refresh
Post-quantum protection arrives as a service, not a rip-and-replace project.
Ready for what’s next
A crypto-agile platform adopts new standards as they are approved.
Why act before quantum computers arrive
Encrypted data stolen today can be stored and decrypted later, once a large enough quantum computer exists. For information that must stay confidential for years — defense plans, health records, intellectual property — the risk is already here. U.S. federal guidance, including OMB M-23-02, directs agencies to plan their migration to post-quantum cryptography now.
How XQ applies post-quantum protection
- Quantum-seeded keys. Keys are generated at the edge from high-entropy, quantum-seeded material.
- Post-quantum algorithms. XQ uses NIST-standardized post-quantum algorithms, including Dilithium, alongside AES-256-GCM.
- Per-object protection. Every object has its own key, so protection is applied object by object rather than all at once.
- Crypto-agile by design. Algorithms can change without touching your applications or storage.
Plan your post-quantum migration with XQ.
Delivered as a service
Because XQ is a managed service, new encryption standards are incorporated automatically and your security posture improves without hardware, software or network replacement. Read how XQ maps to the M-23-02 memo on migrating to post-quantum cryptography.
Part of a complete Zero Trust Data layer
Post-quantum algorithms protect the object-level encryption and key management at the core of XQ, so long-lived data stays protected end to end.

FAQ
Post-quantum cryptography, answered directly.
What is a harvest-now, decrypt-later attack?
An attacker collects encrypted data today and stores it until a quantum computer can break the encryption. Data that must stay confidential for years is at risk now, even before such computers exist.
Which post-quantum algorithms does XQ use?
NIST-standardized post-quantum algorithms, including Dilithium, alongside AES-256-GCM, with high-entropy, quantum-seeded key material.
What does “quantum-seeded” key material mean?
XQ’s Quantum service streams quantum random number generator (QRNG) entropy to the edge, where it seeds local key generation. Organizations that require a specific entropy source can substitute their own.
Do we need new hardware or software for post-quantum protection?
No. XQ is delivered as a service, so new encryption standards are incorporated automatically, without replacing hardware, software or networks.
Does XQ help with federal PQC migration requirements?
Yes. XQ’s crypto-agile, per-object encryption supports agencies planning their migration under federal guidance such as OMB M-23-02.
