Everything you need to stay safe
Google Safe Browsing
Every URL is checked against Google's database of suspected phishing, malware, and social engineering sites. Advisory provided by Google Safe Browsing.
Payment Redirect Detection
Inline scripts that may silently redirect you to PayPal, Stripe, crypto platforms, or other payment services are detected and flagged as potentially malicious.
Instant Warning Page
When a site is suspected to be dangerous, you see a warning page explaining why it was flagged - before anything renders.
