Sentraio - Browser Security

About

Sentraio protects your browsing from phishing, malware, and data breaches in real time. Four layers of defense working together to catch threats that other tools miss.                                                                                                      
   
  ━━━ HOW IT WORKS ━━━                                                                                                                                                                                                                                                         
                                                                  
  Every website you visit is automatically checked before it loads. If a threat is detected, Sentraio blocks it instantly and shows you exactly what was caught and why. On install, a full security scan checks your browsing history, installed extensions, and email for
  data breaches — so you know your risk level from day one.

  ━━━ FOUR LAYERS OF PROTECTION ━━━

  Layer 1: Real-Time URL Scanning
  Every URL is checked against multiple threat intelligence feeds including Google Web Risk, PhishTank, URLhaus, and ThreatFox. Known phishing sites, malware distribution pages, and scam URLs are blocked before they can load. Over 56,000 malicious domains are tracked and
   updated hourly.

  Layer 2: Page Content Analysis
  A built-in content scanner analyzes every page for signs of phishing — fake login forms, brand impersonation (covering 16 major brands including PayPal, Google, Microsoft, Apple, and Amazon), urgency language designed to trick you, hidden iframes, and cross-domain form
   submissions. Pages are scored 0-100 and automatically blocked if they reach the danger threshold.

  Layer 3: Browsing History Scan
  On install, Sentraio scans your last 30 days of browsing history (up to 100 unique domains) to find dangerous sites you may have already visited. Results are checked in batch against our threat intelligence database so you can see your exposure instantly.

  Layer 4: AI-Powered Verification (Premium)
  For borderline pages that look suspicious but aren't in any database yet, Sentraio uses AI analysis to make a final determination. This catches sophisticated, brand-new phishing pages that evade traditional detection — the kind that look pixel-perfect but are designed
  to steal your credentials.

  ━━━ DATA BREACH MONITORING ━━━

  Check if your email has been exposed in known data breaches using the Have I Been Pwned database — covering billions of breached records. Get alerts when new breaches are discovered so you can change compromised passwords immediately.

  ━━━ EXTENSION SECURITY AUDIT ━━━

  Sentraio scans every installed extension on your browser for dangerous permissions, known malicious IDs, and excessive access requests. Each extension gets a risk verdict — safe, low risk, medium risk, high risk, or malicious — with specific reasons explaining why.
  Know exactly which extensions to keep and which to remove.

  ━━━ WHAT GETS BLOCKED ━━━

  • Phishing websites that impersonate banks, email providers, and online services
  • Malware distribution sites that try to install harmful software
  • Tech support scams with fake virus warnings
  • Fake login pages designed to steal your passwords
  • Command-and-control servers used by botnets
  • Known fraud and scam domains

  ━━━ PRIVACY FIRST ━━━

  Your privacy is non-negotiable:

  • We never store your browsing history on our servers
  • URL checks use hash prefixes — we never see the full URLs you visit
  • History and extension scans run locally in your browser
  • All data is encrypted in transit (TLS) and at rest (AES-256)
  • No tracking pixels, no analytics scripts, no ad networks
  • We don't sell your data. Ever.

  ━━━ SMART BLOCK PAGE ━━━

  When a threat is blocked, you see a clear explanation of what was detected and why it's dangerous. One-click bypass if you trust the site. No confusing error screens or dead ends.

  ━━━ WORKS EVERYWHERE ━━━

  Install on Chrome, Edge, Brave, or any Chromium-based browser. Your account syncs across all devices. Log in once on the dashboard and the extension picks up your session automatically.
