Inform: On multi-tenant hosting platforms (like GitHub Pages or Vercel), an informational badge (i) and top banner remind you that user-generated subdomains are evaluated independently. Warn: If you land on an unrated, suspicious, or typosquatted domain, an alert badge (!) and top warning banner caution you before you interact with the page. Block: Known malicious sites or domains on your personal block list trigger a red status badge (X) and an instant full-screen overlay to block access. 🎯 Frequently Asked Questions (FAQ) Q: What is SquatGuard? SquatGuard is a real-time browser security extension that protects you against phishing attempts, typosquatting (homoglyph/lookalike domains), and malicious URLs before you interact with them. Q: How does SquatGuard detect suspicious sites? SquatGuard runs heuristic analysis on domain patterns, checks for character substitutions and homoglyphs against safe domain registries, and references local and remote blocklists to flag potential security risks. Q: What do the extension badge icons mean? ✓ (Green): Verified or safe domain listed in trusted datasets. i (Blue): Multi-tenant host (e.g., platforms hosting user-generated content). ? (Blue): Unknown or unrated domain. ! (Orange): Warning—typosquatting or heuristic similarity detected. X (Red): Explicitly blocked domain. Q: Will SquatGuard slow down my browsing speed? No. All string comparisons and regex checks execute asynchronously in fractions of a millisecond using background service workers, ensuring zero impact on page load times. Q: Does adding a domain to "My Safe Domains" bypass all security banners? Yes. Placing a domain on your local safe list bypasses heuristic warnings and displays the green verification badge for that URL. Q: How do I remove a domain I accidentally added to my block list? Open the SquatGuard popup icon, scroll to My Blocked Domains, and click the red ✕ icon next to the domain. The page will instantly rescan and unblock access. Q: How are subdomains evaluated on multi-tenant platforms? When visiting services like Vercel, Firebase, or GitHub Pages, SquatGuard evaluates each sub-path or subdomain individually. This prevents a malicious user-generated site from riding on the trusted reputation of the main parent domain. Q: Why did I get a red block overlay screen? A full-page red overlay appears when a domain is explicitly included on your personal block list or matches severe phishing heuristics. The overlay prevents interaction with the page until you either exit or remove the domain from your block list. Q: How many malicious sites does SquatGuard block automatically? SquatGuard comes pre-loaded with a global threat database of over 450,000 automatically blocked malicious, phishing, and typosquatting domains. This list syncs continuously in the background to protect you against newly identified threats in real time. Q: What categories of websites are included in the 450,000+ block list?SquatGuard automatically blocks over 450,000 domains across multiple high-risk categories: Phishing & Typosquatting: Fake login portals, credential harvesters, and lookalike domains. Adult & NSFW Content: Explicit domains and unverified adult platforms. Academic Integrity Risks: Essay mills, automated student assignment solvers, and homework cheating services. Gaming & Gambling: Unsafe gaming portals, predatory micro-transaction sites, and malicious web games. ⚖️ Legal Disclaimer SquatGuard evaluates security patterns and blocklists in real time.
