End-to-end encrypted communications: what it really takes

"Encrypted" is not a yes/no answer

Many products claim to be "encrypted" while the provider still holds the keys — which means they (or anyone who compromises them) can read your messages. End-to-end encryption (E2EE) means only the communicating parties can read the content. Nobody in the middle, including the platform, can.

The parts that actually matter

• Key management — how keys are generated, exchanged and stored is where most systems fail.
• Forward secrecy — a stolen key today should not unlock yesterday's messages.
• Authentication — encryption without verifying who you are talking to invites man-in-the-middle attacks.
• Metadata — even with content encrypted, who-talks-to-whom can leak a lot.

Match the design to the threat

A consumer chat app and a system handling state or defense-grade communications have very different threat models. Good security starts by being honest about who you are defending against and what they can do.

Our approach

We design E2EE channels with modern primitives, forward secrecy and a threat model defined up front — and, increasingly, with post-quantum readiness so today's confidential traffic stays confidential tomorrow.
