Vendors Claiming Quantum-Safe / Quantum-Proof Crypto

Risk: varies · Confidence: high · Reviewed: 2026-07-19

Verdict

“Quantum-proof” on a homepage is not a cryptographic proof. Buyers should map claims to algorithms, threat models, audits, and operational key management—then compare to NIST PQC and hybrid best practices.

Overview

isquantumproof.com is an educational site. This index collects vendor- and product-shaped pages that discuss public claims of quantum safety. We do not endorse products, and we do not invent private technical details.

When evidence is incomplete, pages say so. When a project publishes concrete post-quantum designs (for example hash-based signature chains), we summarize what is public and what still depends on operations and surrounding classical crypto.

Start with the methodology hub, then open individual vendor pages. For NIST primitives, see /standards/* and /learn/what-is-pqc.

Claim scrutiny (buyer checklist)

Evidence level: partial — not an endorsement.

Marketing / stated claims

Many products use labels such as quantum-safe, quantum-proof, or quantum-resistant

Open questions

Which NIST (or other) algorithms are actually implemented?
What is audited vs aspirational roadmap?

Educational analysis only. Verify primary sources, specs, and audits yourself before any financial or procurement decision.

What breaks

Accepting brand language without algorithm inventory
Ignoring classical fallbacks, bridges, or admin keys still on RSA/ECC
Assuming one quantum-safe component makes the whole system post-quantum

Mitigations

Require algorithm names, parameter sets, and library provenance in writing
Ask for third-party review scope and date
Test hybrid and migration stories for classical components that remain
Use the claim methodology page before any single vendor dossier

FAQ

Is this a scam list?

No. It is a claims-evaluation cluster. Some projects may implement serious PQC; others may over-market. The point is a repeatable buyer checklist.

Will you add every project that says quantum-proof?

Only wave-gated entries with enough public material to write non-thin pages. Volume without evidence is declined.
