Apple Redirects Google Safe Browsing Traffic Through Its Own Proxy Servers to Prevent Disclosing User IP Addresses to Google in iOS 14.5

Apple’s Fraudulent Website Warning is designed to alert you when you’re about to visit a website that is known to host malware, or that is believed to be a phishing site. Previously, that check consulted a database hosted on a Google server, but as of iOS 14.5 it instead uses an Apple proxy to better protect user privacy.

Apple uses the same database that Google uses to identify these sites, taking steps to ensure that Google never sees the URL you were trying to visit, but cautioning that Google may log your IP address.
