The encryption protecting the world today has an expiration date. We built what comes after it.
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.
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.
Encrypted traffic is intercepted and stored.
Quantum computers become powerful enough.
Everything recorded can be read. Retroactively.
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.
Built to hold against today's computers and tomorrow's quantum machines alike.
Only you hold your keys. Not us, not our servers, not anyone in between.
Protection renews itself continuously, so a single breach doesn't unlock the past or the future.
No setup, no expertise, no trade-offs. It simply works.
The provider can read your messages.
Private today. Recorded traffic can be opened by a future quantum computer.
New conversations are protected against quantum attacks when they begin.
Protection against quantum attacks from the first message and renewed throughout the conversation.
Our first product is private communication. The rest is coming. For partnerships, investment and press:
