Adversaries are recording your encrypted data today to unlock it the moment quantum computers arrive. It's called Harvest Now, Decrypt Later. Secuur grades your exposure, then makes you quantum-safe — without changing how your business runs.
RSA-2048 & ECDHE — strong against today's computers, defenceless against tomorrow's. Harvestable right now.
Encrypted traffic copied today can be stored cheaply for years. When a capable quantum computer arrives, every harvested file is decrypted retroactively. Anything that must stay secret for a decade is already at risk.
NIST published FIPS 203, 204 and 205 in 2024 — the official post-quantum algorithms. The waiting game is over; the migration window is open and regulators have started counting.
Finance, healthcare, defense and the largest platforms are mid-migration. Hybrid post-quantum TLS is shipping in browsers today. The question is no longer if — it's whether you're early or exposed.
Imagine someone photocopies your locked diary and keeps the copy in a drawer. They can't read it — the lock is too good. But they're patient. They're waiting for a master key that hasn't been invented. That's Harvest Now, Decrypt Later. The diary is your data. The master key is a quantum computer.
Every login, payment and message is scrambled in transit. Safe — for now.
They can't read it, so they store the scrambled copy and wait. Storage is cheap. Patience is free.
The master key arrives. Today's lock pops in minutes. Every harvested copy is suddenly readable.
The fix isn't a stronger version of the same lock — it's a new kind of lock a quantum computer can't pick. That's post-quantum cryptography, and it's ready today.
Type a domain. We negotiate a real handshake, read its ciphers and signatures, and grade its exposure to Harvest Now, Decrypt Later — A through F. Free to run. No signup, no app changes.
Cryptography keeps changing. The winning move isn't picking the perfect cipher — it's being able to swap ciphers on demand without touching your apps. We call it crypto-agility, and it's the foundation of everything Secuur ships.
We run classical X25519 and post-quantum ML-KEM-768 together. If either is ever broken, the other still holds. No single point of failure.
Ciphers live in a policy layer, not in your code. New standard tomorrow? Flip a setting. Your apps never notice.
Secuur tracks the standards, the deprecations and the threats so your team doesn't. You stay current by default.
Each rests on a problem even a quantum computer finds hard. Secuur deploys all three where they fit best.
Hides secrets inside a grid of points so dense that finding the right one is hopeless — even at quantum speed. Fast and compact; the default for key exchange.
Builds signatures from hash functions we already trust completely. Conservative, battle-tested, and the safest fallback for signing.
Wraps data in deliberate, math-perfect errors only the keyholder can correct. Decades of scrutiny; rock-solid for long-term key transport.
Today's encryption hides a number so big that guessing it would take an ordinary computer billions of years. Totally safe — against ordinary computers.
A quantum computer doesn't guess one number at a time — it explores enormous spaces at once. The billion-year padlock becomes an afternoon's work. So we change the lock to one that math itself can't shortcut. That's all Secuur does — quietly, before the master key exists.
Every grade routes to a fix sized for you — self-serve checkout for smaller teams, a guided plan for regulated ones.
Every Secuur endpoint, API and internal link runs hybrid post-quantum encryption today. We migrated 0% of our own infrastructure first — then wrote down exactly how, so your migration is a known path, not an experiment.
Pick the page built for your world — each cites the standards that apply to you.
Quantum-safe in a weekend, not a fiscal year. No app changes.
Your CBOM, your migration plan — in one sprint.
Examiners are already asking. FFIEC, NY DFS, GLBA.
PHI you encrypt today must stay private for decades.
CNSA 2.0 and CMMC don't wait for you.
Hybrid PQC at your edge in one config line.
The scan is free and takes 20 seconds. Everything after that is sized to fit you.
