Audit browser sandbox security and security settings online for free with our Browser Security Scorer. Evaluate HTTPS transport encryption, referrer policy leakage, and LocalStorage sandbox isolation directly inside client browser RAM.
Open the page to initiate automatic client-side security probes.
Observe your percentage rating and review audit log details.
Click Re-Audit Sandbox to re-evaluate browser security settings.
Verifies whether connection traffic is encrypted over secure TLS protocols.
Inspects document referrer headers (document.referrer) to verify if URL path leakages are prevented.
All security audit calculations execute inside client browser memory. Zero security telemetry is uploaded to external servers.
Browser security architecture isolates web pages into sandboxed execution environments. HTTPS transport verification (window.location.protocol === 'https:') confirms that communication channels are encrypted with modern TLS ciphers.
Referrer policy enforcement evaluates whether navigation parameters (document.referrer) leak sensitive URL path structures to destination origins. Shielded referrer policies restrict data sharing across cross-origin boundaries.
Storage API isolation testing verifies that client storage subsystems (localStorage) execute under strict same-origin isolation rules, computing security ratings entirely in browser RAM.
