01 · What Ciphera builds
Five things, one principle
Ciphera ships four privacy-first products and one open-source library. They share a single design rule: collect as little as possible, and encrypt what remains before it leaves your device.
Pulse
Privacy-first, cookieless web analytics — no cookies, no fingerprinting, no cross-visit tracking. Open source under AGPL-3.0, and GDPR compliant by design.

Ciphera ID
A zero-knowledge identity provider. One account works across every Ciphera service, and your password is proven with OPAQUE (RFC 9807) — it never reaches our servers.

Ciphera Captcha
Bot protection built on adaptive proof-of-work and puzzle challenges. Stateless, self-hosted, and free of third-party trackers.

Ciphera Relay
Transactional email infrastructure that runs on our own mail servers, so no third-party email provider sees who we write to or why.

Our open-source OPAQUE authentication library — a Rust core plus Go and browser SDKs, published under Apache-2.0. It is the cryptography behind Ciphera ID and Pulse auth.

Frequently asked
Ciphera is a Belgian privacy-software company (Ciphera BV) that builds zero-knowledge infrastructure and applications. Its products encrypt your data before it reaches Ciphera’s servers, so the company can run each service without being able to read what you store.
Both. Ciphera is the company — Ciphera BV — and it builds a family of privacy products under that name: Pulse, Ciphera ID, Ciphera Captcha, Ciphera Relay, and the open-source Tessera library. When people say “Ciphera”, they usually mean the company or the platform as a whole.
Cookieless web analytics with no consent banner (Pulse), zero-knowledge login and account management (Ciphera ID), bot protection that doesn’t profile your visitors (Ciphera Captcha), and transactional email with no tracking pixels (Ciphera Relay). Tessera, the OPAQUE library underneath, is available to developers on its own.
Ciphera BV is registered in Belgium (KBO/BCE 1013.721.660, De Kleetlaan 2, 1831 Diegem) and operates under EU law — GDPR and NIS2. Customer data is hosted on Swiss infrastructure, protected by the Federal Act on Data Protection (FADP) alongside the GDPR.
Pulse has a free tier and paid plans, and you can explore the live demo without signing up. Ciphera’s other products are paid. Nothing here is ad-funded — you are the customer, never the product, and there is no data resale.
Partly. Tessera — the OPAQUE authentication library behind Ciphera ID — is open source under Apache-2.0, and the Pulse analytics dashboard is open source under AGPL-3.0. The remaining services are not open source today, though more of the platform is being opened over time.
