Post-quantum security

Encryption built
for the quantum era.

The encryption protecting the world today has an expiration date. We built what comes after it.

SCROLL
01 / The problem

Harvest now.
Decrypt later.

Almost everything private online is protected by cryptography that quantum computers will break. And no one has to wait for that day: encrypted data can be collected today and opened later. Every secret with a long life is already at risk.

28–49%

Estimated chance that a quantum computer able to break today’s encryption exists within 10 years. Within 15 years: 51–70%. Source: 26 experts surveyed in the Quantum Threat Timeline Report 2025, Global Risk Institute.

TODAY

Encrypted traffic is intercepted and stored.

TOMORROW

Quantum computers become powerful enough.

THEN

Everything recorded can be read. Retroactively.

02 / What we built

Not a patch.
A new foundation.

LL3 has built a security core designed from day one for a world with quantum computers. Not old cryptography with a new label: a different starting point.

01

Quantum-resistant

Built to hold against today's computers and tomorrow's quantum machines alike.

02

Nothing to hand over

Only you hold your keys. Not us, not our servers, not anyone in between.

03

Always in motion

Protection renews itself continuously, so a single breach doesn't unlock the past or the future.

04

Invisible

No setup, no expertise, no trade-offs. It simply works.

03 / Where you stand

Not all encryption
is built for what’s coming.

LEVEL 0

No end-to-end encryption

The provider can read your messages.

LEVEL 1

End-to-end encryption

Private today. Recorded traffic can be opened by a future quantum computer.

LEVEL 2

Quantum-resistant start

New conversations are protected against quantum attacks when they begin.

LEVEL 3 LL3

Quantum-resistant, end to end, all the time

Protection against quantum attacks from the first message and renewed throughout the conversation.

04 / Feel it

Type something private.

Real encryption, running locally in your browser. Nothing leaves this page.
