The actual website address is never shared with the safe browsing provider. If you have China mainland set as your region in the Language & Region pane of System Preferences, Safari may also use Tencent Safe Browsing to do this check. Before you visit a website, Safari may send information calculated from the website address to Google Safe Browsing to check if the website is fraudulent. A fraudulent website masquerades as a legitimate one, such as a bank, financial institution, or email service provider. Phishing is a fraudulent attempt to steal your personal information, such as user names, passwords, and other account information. Get a warning if the site you’re visiting is a suspected phishing website.
