Utilvo Shield

Dangerous links never get to load

Scans every navigation, download, search result, and social link in real time — the tab redirects to a warning screen before a flagged page can render anything.

  • Blocks before any content renders
  • Live safety badges on search & social results
  • Google Safe Browsing + local heuristics

Utilvo EdgeShield

Rotating-IP cloud scrapers never reach your server or GA4

Zero-conflict Nginx hash-map rules, Cloudflare WAF ASN expressions, and a <1KB WebGL SwiftShader/llvmpipe browser filter that blocks 1,500+ rotating Singapore/China bot IPs (AS132203, AS45102, AS136907) while whitelisting Googlebot and Bingbot.

  • 1-line Linux Nginx installer with automatic nginx -t rollback
  • Detects WebGL SwiftShader / llvmpipe virtual GPUs & OS spoofing
  • Stops fake Singapore bot traffic in Google Analytics 4 with zero SEO impact

Utilvo|Sandbox

Open a Link

Active

Paste a suspicious URL — it opens in an isolated preview with 30+ protection layers.

https://example.com
Current level: Medium
Utilvo Sandbox

Open it anyway — safely

Previews a link inside a fully isolated, monitored frame. Cookies, storage, and network exfiltration stay contained — nothing touches your real browser profile.

  • Locked frame — no top-level navigation, no popups
  • Exfiltration blocked at the network level
  • Canvas & audio fingerprinting neutralized

Your login session never leaves your browser

Utilvo PhishBuster

A fake login page can't fool your browser

Reads page layout, form fields, and even fake Browser-in-the-Browser popups to catch copies of 30 real brand login pages the instant they load.

  • Reads layout & form fields, not just the URL
  • Catches Browser-in-the-Browser fake popups
  • Full-page interception, not a dismissible overlay
