Quantum-safe today.
Not in 2029.Quantum cyber security — built on NIST's post-quantum standards, shipping in production now.
RankShield defends your data, your AI, and the systems that must stay confidential for decades against "harvest now, decrypt later" — built on NIST's finalized standards (ML-KEM, ML-DSA), hybrid and crypto-agile, never weaker than today's encryption.
The clock on today's
encryption is running.
"Harvest now, decrypt later": adversaries steal encrypted data today to open once quantum computers mature — which NIST calls one of the main reasons the transition is urgent before any such machine exists. A cryptographically-relevant quantum computer doesn't exist yet; experts (GRI 2025) put the odds within a decade at 28–49%. You don't need a date to be exposed — only data that must outlive it.
Not experimental.
Standardized.
In August 2024 NIST finalized the first post-quantum standards — ML-KEM (FIPS 203), ML-DSA (FIPS 204), SLH-DSA (FIPS 205) — and said plainly they "can and should be put into use now." RankShield builds on those official standards, deployed the responsible way: hybrid, so you're never worse off than classical.
Already in production.
Not a roadmap.
Every RankShield signature, key exchange, and connection is post-quantum now: composite ML-DSA-65 + Ed25519 signatures, ML-KEM via hybrid post-quantum TLS (X25519MLKEM768), a crypto-agile algorithm registry, and a QRNG entropy source. Ahead of the 2030/2031 deadlines — not chasing them.
Agility beats
any single algorithm.
PQC is young; standards will evolve. RankShield keeps algorithms in a swappable registry and signs with composite (classical + post-quantum) keys, so crypto can rotate centrally without re-architecting — the readiness the 2026 executive order's Cryptographic Bill of Materials now expects.
"Quantum-safe by 2030"
means crypto-agile today.
By the Mosca inequality, if your data's shelf-life plus migration time exceeds the time to quantum, you're already exposed. Migrations take years. The move is the same whether you're protecting decade-long secrets or securing AI agents: become post-quantum and crypto-agile now.
What is quantum cyber security?
Quantum cyber security is protecting systems against the threat quantum computing poses to today's encryption. In practice, that means post-quantum cryptography — encryption designed to resist both classical and quantum computers, running on the ordinary hardware you already have (it is not quantum key distribution, which needs special equipment). It also means strong entropy behind every key, and crypto-agility so the algorithms can evolve. RankShield combines all three: NIST's standardized post-quantum algorithms, a quantum random-number entropy source, and a swappable algorithm registry — deployed in production today so data and identities stay safe through and beyond "Q-Day."
Why is the quantum threat urgent before a quantum computer exists?
Because of "harvest now, decrypt later." Adversaries can copy your encrypted data today — M&A terms, medical records, government secrets, privileged files — and simply store it until a quantum computer can break the encryption. NIST names this as one of the main reasons the post-quantum transition is urgent now: anything that must stay secret for years is already at risk, even though the machine that opens it doesn't exist yet. How close is "Q-Day"? No one knows. A cryptographically-relevant quantum computer does not exist, and honest estimates are probabilistic: experts surveyed by the Global Risk Institute (2025) put the odds within a decade at roughly 28–49%. In 2025, a Google researcher estimated RSA-2048 could be broken with under a million noisy qubits — a theoretical projection under explicit assumptions, about 20× lower than a 2019 figure, but still no hardware exists at that scale (Google's own Willow chip, at 105 physical qubits, makes no cryptographic claim). The lesson isn't to predict the date; it's the Mosca inequality: if your data's required secrecy plus your migration time exceeds the time to quantum, you're exposed today.
What does RankShield ship today — and why "not 2029"?
Because it's already in production, mapped to NIST's finalized standards — while most vendors' public quantum plans point to 2027–2035. NIST says the standards "can and should be put into use now," and RankShield does:
Composite ML-DSA-65 + Ed25519 (FIPS 204) — every receipt, certificate, and attestation is post-quantum signed.
ML-KEM (FIPS 203) via hybrid post-quantum TLS (X25519MLKEM768) — data in transit is quantum-safe by default and never weaker than classical.
Algorithms live in a registry with an allowlist — rotate or upgrade without re-architecting, the readiness a Cryptographic Bill of Materials expects.
A quantum random-number source strengthens the randomness behind every key and token — mixed with classical entropy, never trusted alone.
This is not "quantum-proof" — nothing honestly is. It's standards-based, hybrid, verifiable, and live, ahead of the 2030/2031 deadlines.
What is crypto-agility, and why does it matter more than any single algorithm?
Crypto-agility is the ability to change cryptographic algorithms quickly — without rebuilding your systems. It matters because post-quantum cryptography is young: NIST's deployment standards are final, but its transition timeline (NIST IR 8547, still a draft) and the algorithms themselves will keep evolving, and one considered safe today may need replacing tomorrow. Organizations that hard-coded RSA decades ago know how painful a forced migration is. RankShield is crypto-agile by design: algorithms live in a registry with an allowlist, signatures are composite (a classical and a post-quantum algorithm together), and crypto can be rotated or added centrally. It's also what new policy expects — the 2026 US executive order calls for a Cryptographic Bill of Materials, a living inventory of the crypto you run, which is only practical if your stack is agile in the first place. Agility is readiness for change, not a guarantee any one algorithm is unbreakable.
Is a QRNG the same as post-quantum cryptography?
No — and we're precise about it. A quantum random number generator (QRNG) produces randomness from a physical quantum process; post-quantum cryptography is the set of algorithms that resist quantum attacks. They're complementary. Every key, token, and nonce is only as strong as the randomness behind it, so RankShield uses a QRNG as a true-entropy source — but always mixed with the operating system's secure randomness, and with safe fallback to classical entropy if the source is ever unreachable, so it can never weaken or block the system. A QRNG hardens the foundation; it is not post-quantum cryptography by itself, and it is not a defense against a quantum computer. The algorithms (ML-KEM, ML-DSA) are.
When do I actually need to be quantum-safe?
Sooner than the headline dates suggest. The policy clock is concrete: the 2026 US executive order (EO 14412) requires federal agencies to move high-value assets to post-quantum key establishment by Dec 31, 2030 and signatures by Dec 31, 2031, and directs CISA and NIST to define a Cryptographic Bill of Materials. NIST's draft transition timeline (IR 8547) would deprecate RSA/ECC after 2030 and disallow after 2035 — still a draft, a direction, not final policy. The EU's coordinated roadmap targets national first steps by end-2026 and broad transition by 2035. But the real trigger is the Mosca inequality, not any single date: because migrations take years, "quantum-safe by 2030" means crypto-agile today. RankShield gives you that posture now — post-quantum signing and transport, verifiable, and crypto-agile — so you're ahead of the deadlines instead of racing them.
Are you already exposed? The Mosca test.
Mosca's inequality: if your data's required secrecy (X) plus your migration time (Y) reaches the years until quantum (Z), an adversary can harvest today and decrypt later — you're exposed now. Drag to model your own numbers.
Exposed today
Ask RankShield about quantum security.
What is quantum cyber security?
Quantum cyber security is protecting systems against the threat quantum computing poses to today’s encryption. In practice it means deploying post-quantum cryptography — NIST’s 2024 standards ML-KEM and ML-DSA — plus strong entropy and crypto-agility, so data and identities stay safe through and beyond "Q-Day." RankShield builds this into production today.
What is post-quantum cryptography?
Encryption designed to resist both classical and quantum computers, running on ordinary hardware (unlike quantum key distribution). NIST finalized the first standards in August 2024 — ML-KEM (FIPS 203) for key exchange, ML-DSA (FIPS 204) and SLH-DSA (FIPS 205) for signatures — to replace the RSA and elliptic-curve algorithms a quantum computer could eventually break.
What is "harvest now, decrypt later"?
A strategy where adversaries steal encrypted data today and store it to decrypt once quantum computers mature. NIST cites it as one of the main reasons the post-quantum transition is urgent now — because data with a long shelf life is already at risk, even though the computer that breaks it does not yet exist.
When will quantum computers break encryption (when is Q-Day)?
No one knows, and a cryptographically-relevant quantum computer does not exist yet. Experts surveyed by the Global Risk Institute (2025) estimate a 28–49% chance within ten years. The point is not the date: if your data must stay secret past 2030, you are already exposed.
What are ML-KEM and ML-DSA?
NIST’s standardized post-quantum algorithms. ML-KEM (FIPS 203) handles key exchange; ML-DSA (FIPS 204) handles digital signatures. RankShield uses ML-KEM in hybrid TLS and composite ML-DSA-65 (paired with Ed25519) for signatures — ML-DSA-65 is NIST Category 3, roughly 192-bit security.
Is post-quantum cryptography standardized yet?
Yes. NIST finalized FIPS 203, 204, and 205 on August 13, 2024, and states they "can and should be put into use now." RankShield builds on those official standards — not experimental algorithms.
Is RankShield "quantum-proof"?
No — and no honest vendor should claim that. RankShield is quantum-safe: it uses NIST-standardized post-quantum algorithms in a hybrid, crypto-agile design, so you are protected against the quantum threat and never worse off than classical encryption. "Proof" implies a guarantee math cannot honestly give.
What is crypto-agility?
The ability to change cryptographic algorithms quickly, without rebuilding your systems. It matters because PQC is young and standards will evolve. RankShield keeps algorithms in a swappable registry and uses composite signatures, so it can rotate crypto centrally — the posture the new Cryptographic Bill of Materials requirement expects.
Is a QRNG the same as post-quantum cryptography?
No. A quantum random number generator improves the randomness behind keys and tokens; post-quantum cryptography is the algorithms that resist quantum attacks. They are complementary. RankShield uses both — a QRNG entropy source (mixed with classical randomness, with safe fallback) and standardized post-quantum algorithms.
When do I actually need to be quantum-safe?
Sooner than the headline dates, per the Mosca inequality: if your data’s shelf-life plus migration time exceeds the time to quantum, you are already exposed. NIST says begin now; the 2026 US executive order sets 2030/2031 federal deadlines; migrations take years. "Quantum-safe by 2030" means crypto-agile today.
