How It Works
Protection in 3 Simple Steps
Install, open any page, and BlurShield takes care of the rest.
01
Install & Sign In
Add BlurShield from the Chrome Web Store. Sign in with Google to start your free 7-day trial — no card needed.
02
Auto-Scan Every Page

Core Features
Everything You Need to Stay Safe
From auto-detection to meeting protection — BlurShield covers every angle.
Auto-Detection Engine
57 regex patterns detect API keys, tokens, passwords, and PII from AWS, GitHub, Stripe, OpenAI, Google Cloud, and 25+ more services in real-time.
Instant Blur Protection
Secrets are automatically blurred with a customizable Gaussian blur. Double-click or hover to temporarily reveal individual items.
Pre-Meeting Scan
Automatically scans all open tabs before a Zoom, Google Meet, or Microsoft Teams call starts. Shows exactly which tabs have exposed secrets.
Custom Blur Zones
Click any element on any page to manually blur it. Perfect for dashboards, balances, personal info, or anything the auto-scanner can't catch.
Clipboard Guard
Tracks copied secrets temporarily in memory and warns before sensitive text is pasted — with options to Allow, Redact, or Cancel.
Leak Preview Mode
Highlights all detected secrets with red outlines instead of blurring — perfect for auditing a page before a meeting.
Meeting Mode
Blur all page content instantly from the BlurShield popup. Perfect for when someone unexpectedly asks to see your screen.
Blurred Screenshots
Capture a screenshot of the current tab with all blurs intact. Download as PNG — safe to share with your team.
Screen-Share Intercept PRO
Uses your browser's screen-share API to run a security scan before a website begins sharing your screen. Works with browser-based sharing in Meet, Zoom, Teams, Loom, and similar web apps.
Security Score PRO
Real-time security score based on the severity and count of detected secrets on the current page. See Critical, High, and Medium severity badges.
Stats Dashboard PRO
7-day activity chart showing secrets blurred, times revealed, active days, and custom zones saved. Track your protection over time.
Domain Whitelisting
Whitelist trusted domains where you don't need protection — like internal tools, dev environments, or known-safe sites.
Custom Patterns PRO
Add your own regex patterns to detect company-specific secrets, internal project IDs, or any custom sensitive data format.
Screen-Share Protection Banner PRO
While a website is sharing your screen, a banner confirms that BlurShield is active and shows how many secrets are protected.
