The threat is already here

Quantum-proof your business before the future breaks your encryption.

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.

Why now

Three facts that put a clock on your encryption.

01

Harvest Now, Decrypt Later

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.

02

The standards are finalized

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.

03

Your sector is already moving

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.

Explain it simply

A locked box you can't open… yet.

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.

STEP 01 · TODAY

Your data travels, encrypted

Every login, payment and message is scrambled in transit. Safe — for now.

STEP 02 · TODAY

An adversary copies it anyway

They can't read it, so they store the scrambled copy and wait. Storage is cheap. Patience is free.

STEP 03 · THE FUTURE

A quantum computer opens it

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.

Secuur Readiness Scan

Get your quantum-risk grade in 20 seconds.

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.

  • A–FA single grade your whole team understands.
  • deep$99 upgrade reads every layer: TLS, VPN, email, stored data.
  • routeA low grade routes you straight to the right fix for your size.

The Secuur approach

Don't bet on one algorithm. Stay agile.

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.

01

Hybrid by default

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.

02

Swap without redeploying

Ciphers live in a policy layer, not in your code. New standard tomorrow? Flip a setting. Your apps never notice.

03

Never think about it again

Secuur tracks the standards, the deprecations and the threats so your team doesn't. You stay current by default.

The new locks

Three families of quantum-safe math.

Each rests on a problem even a quantum computer finds hard. Secuur deploys all three where they fit best.

Lattice-based

ML-KEM & ML-DSA

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.

FIPS 203 · FIPS 204
Hash-based

SLH-DSA

Builds signatures from hash functions we already trust completely. Conservative, battle-tested, and the safest fallback for signing.

FIPS 205
Code-based

Classic McEliece

Wraps data in deliberate, math-perfect errors only the keyholder can correct. Decades of scrutiny; rock-solid for long-term key transport.

Today's lock

A padlock with a secret number

Today's encryption hides a number so big that guessing it would take an ordinary computer billions of years. Totally safe — against ordinary computers.

Tomorrow's master key

A computer that guesses in an afternoon

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.

The ladder

One scan. Four ways to act on it.

Every grade routes to a fix sized for you — self-serve checkout for smaller teams, a guided plan for regulated ones.

We went first

We hardened our own fleet before we sold you anything.

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.
