Command & Code: Web Firewall

PROTECT YOUR BROWSING WITH ENTERPRISE-GRADE SECURITY Web Firewall Extension brings professional-grade web security to your browser, protecting you from XSS attacks, SQL injection, malicious scripts, and invasive tracking—all while respecting your privacy with 100% local-only processing. Developed by Command & Code Labs, a leader in browser security innovation, this extension empowers users to take control of their online safety without compromising performance or privacy. THE THREATS YOU FACE DAILY Every time you browse the web, you're exposed to: • CROSS-SITE SCRIPTING (XSS): Malicious scripts injected into legitimate websites that steal your passwords, session tokens, and personal data • SQL INJECTION: Attackers manipulating database queries through URL parameters to breach website security • TRACKING & ANALYTICS: Hidden scripts that follow you across the web, building detailed profiles of your browsing habits • MALICIOUS REDIRECTS: Fake JavaScript and data URLs designed to hijack your browser and execute harmful code • COOKIE THEFT: Unauthorized access to your browser storage, exposing login credentials and sensitive information Traditional security solutions can't catch everything. Antivirus software stops downloads, but not web-based attacks. Ad blockers focus on ads, not security. You need specialized protection designed specifically for modern web threats. HOW WEB FIREWALL PROTECTS YOU Web Firewall acts as your personal security guard, inspecting every web request before it reaches your browser: 1️⃣ REAL-TIME THREAT BLOCKING • Analyzes URLs, scripts, and resources in milliseconds • Blocks malicious content before it can execute • Uses Chrome's native Declarative Net Request API for zero performance impact 2️⃣ INTELLIGENT SECURITY MODES • Balanced Protection: Daily browsing security that doesn't break websites • Maximum Security: Enhanced protection for high-risk environments • Custom Rules: Power users can create their own advanced filters 3️⃣ COMPREHENSIVE THREAT COVERAGE • XSS Prevention: Blocks script injection attacks (javascript:, data: URLs, inline scripts) • SQL Injection Defense: Stops database manipulation attempts (UNION SELECT, OR '1'='1') • Tracking Protection: Eliminates Google Analytics, tracking pixels, and data brokers • Admin Path Security: Prevents accidental exposure to sensitive admin interfaces • Browser Storage Protection: Guards your cookies, localStorage, and sessionStorage 4️⃣ PRIVACY-FIRST ARCHITECTURE • 100% local processing—no data ever leaves your device • No cloud connections, no external servers, no data collection • Telemetry stored locally only, fully under your control • Export your security data anytime in JSON or CSV format REAL-TIME ANALYTICS DASHBOARD Unlike other security tools that work silently in the background, Web Firewall gives you complete visibility into your protection: • Live threat counter on your toolbar badge—see exactly how many attacks we've blocked • Detailed analytics page showing: ✓ Total blocked requests with timestamps ✓ Top blocked domains (analytics trackers, malicious sites) ✓ Most active security rules and their effectiveness ✓ Chronological log of every blocked threat with full details • Export capabilities for security analysis and reporting • Rule ID tooltips—hover over any rule to understand what it blocked and why ADAPTIVE SECURITY MODES Choose the perfect balance between security and usability: BALANCED PROTECTION MODE (Recommended) Perfect for everyday browsing.
