Prothean Shield

Chrome / Safari Extension — Privacy & Speed

Prothean Shield is a lightweight browser extension for Chrome and Safari that blocks trackers, ads, and invasive third-party scripts. Beyond privacy, it delivers measurable speed and efficiency gains—faster page loads, lower CPU usage, less memory, and better battery life on your laptop.

Speed & Efficiency Enhancements

By blocking requests before they load, Prothean Shield reduces what your browser and laptop must process. The result is a leaner, faster experience.

Faster Page Loads

Fewer third-party requests mean less waiting. Typical sites load 15–40% faster with trackers and ads blocked.

Lower CPU

Blocked scripts never execute. Less JavaScript in the main thread keeps the browser responsive and reduces fan spin.

Less Memory

Fewer DOM nodes, fewer iframes, fewer ad networks. Memory use drops—especially on tabs left open.

Better Battery

Fewer network calls and less CPU work extend laptop battery life, especially on Wi‑Fi–heavy sessions.

How It Works

Shield uses three core protocols:

Veil Protocol — Tracker blocking. Intercepts known tracking domains before they connect.
Veridian E.C.H.O. — Cosmetic filtering. Hides ad containers and clutter without breaking layout.
Darwin Protocol — Energy-aware rules. Adapts blocking to minimize CPU and network impact.

All processing is deterministic and local. No cloud dependency. Your browsing stays private, and your machine stays lean.

Enterprise & Sovereign

Prothean Shield is built for users who demand both privacy and performance. Deterministic validation, Guardian EGI integration, and zero external API calls. Available for Chrome and Safari.
