Browser Sentinel

Monitor every connection your browser makes — detect unencrypted traffic, hidden servers, and extensions phoning home beyond their declared permissions.

About

Browser Sentinel gives you complete visibility into what your browser is doing behind the scenes. Every network request from every tab and every installed extension is intercepted, analysed, and displayed in a real-time dashboard — showing you exactly where your data is going, whether it is encrypted, and whether the destination server is visible or hiding behind a proxy.

What does it monitor?

All browser traffic — every HTTP and HTTPS request from every tab
Extension requests — network calls made by installed Chrome extensions
Encryption status — flags any data sent over unencrypted HTTP
Server visibility — detects when destination servers hide behind CDN or reverse proxy services
Permission compliance — compares each extension's actual requests against its declared host_permissions and flags undeclared destinations

Features
