Phishing Protection concepts

This page discusses Phishing Protection core concepts.


Phishing Protection is a phishing countermeasure platform that helps to detect phishing attacks against your users. The Phishing Protection Submission API also enables you to submit URLs suspected to be unsafe to Safe Browsing. Any URLs that are confirmed to match the Safe Browsing Policies will be added to the Safe Browsing list, which is used by over three billion devices to show warnings when a user visits a known unsafe web resource. Common sources of these URLs are customer reports or internal phishing detection results.

Safe Browsing Policy

Only submitted items that are confirmed to match the Safe Browsing Policy will be added to the Safe Browsing List. The Safe Browsing List includes the following areas:


Since 2006, Safe Browsing has warned users when they attempt to navigate to sites that might be malicious. Malware is software specifically designed to harm a device, the software it's running, or its users.

Unwanted Software

In 2014, we added protection against a broad category of harmful technology that we now call "Unwanted Software". For example, programs disguised as helpful downloads that actually make unexpected changes to your computer, like switching your homepage or other browser settings to ones you don't want.

Social Engineering

Since 2005, Safe Browsing has protected users across the web from Social Engineering attacks. A Social Engineering attack tricks users into performing an action that they normally would not if they knew the true identity of the attacker. A common example is Phishing, which is when a page tries to steal a user's password or other personal data.
