Imagine a web browser built with Proton’s guiding philosophy at its core — a platform where privacy, intelligence, and design coexist in harmony. This vision takes form as Lumen, a new kind of browser designed to unite Proton’s ecosystem into a single, secure experience.

The name Lumen means light or illumination, symbolizing clarity, transparency, and enlightenment — the very principles Proton stands for. It captures the essence of a browser that helps users navigate safely through the modern web’s dark corners while illuminating truth, privacy, and control. Lumen is more than a browsing tool; it is a guide — shedding light on what matters while keeping the user’s identity invisible to surveillance. Its modern, internationally resonant name embodies innovation, trust, and simplicity — qualities that have long defined Proton’s brand.

Unified Proton Ecosystem:
Lumen would seamlessly integrate ProtonMail, ProtonVPN, Proton Drive, and other Proton services into a single encrypted hub. This consolidation ensures that communication, storage, and browsing remain consistent, secure, and fully within Proton’s protected network — eliminating dependence on external services that compromise privacy.

Privacy and Security by Design:
Lumen could introduce an advanced shield system blocking ads, trackers, and malicious scripts by default. Optional Tor routing would enable true anonymity, while built-in end-to-end encryption could safeguard even active browsing sessions. In Lumen, privacy is not an extension — it is the default state.

Proton Search and AI Intelligence:
To ensure independence from corporate data mining, Proton Search would power neutral, private, and non-profiling results. Alongside it, a built-in, locally processed AI assistant — perhaps an evolution of Lumo — could help users compose emails, summarize pages, and generate content securely. In keeping with the Lumen philosophy, this AI would illuminate without intruding, offering guidance without compromise.

Design and Experience:
Inspired by modern minimalist browsers like Brave, Comet, and Arc, Lumen would emphasize focus and fluidity. The interface would feel weightless yet powerful, allowing users to move between email, cloud storage, and browsing effortlessly — all under the same privacy-first umbrella.

Lumen stands as a beacon for what a browser should be: intelligent, private, elegant, and built on trust. It embodies Proton’s mission to empower users through technology that enlightens rather than exploits. Proton has the opportunity to make Lumen the light that guides the next era of secure, user-centric internet exploration.
