Making the world’s information safely accessible.

Safety First

Keeping over five billion devices safer.

Google Safe Browsing helps protect over five billion devices every day by showing warnings to users when they attempt to navigate to dangerous sites or download dangerous files. Safe Browsing also notifies webmasters when their websites are compromised by malicious actors and helps them diagnose and resolve the problem so that their visitors stay safer. Safe Browsing protections work across Google products and power safer browsing experiences across the Internet.

Our Transparency Report includes details on the threats that Safe Browsing identifies. The Transparency Report includes our Site Status diagnostic tool that you can use to see whether a site currently contains content that Safe Browsing has determined to be dangerous.

Increased Protection

Enhanced Safe Browsing

Users who require or want a more advanced level of security while browsing the web can enable Enhanced Safe Browsing.

Users who set up Enhanced Safe Browsing for their Google Account or Chrome browser will get the highest level of protection. We are always working to add new protections; some of the protections that are available now are listed below.

On Google Chrome, Enhanced Safe Browsing users will benefit from the following additional protections:

  • Real-time checks against lists of known phishing and malware sites
  • The option to request Google to perform deeper scans of files they’ve downloaded to check for malware and viruses
  • Protection against previously unknown attacks when navigating to sites
  • Tailored protections based on your risk level

Across other Google products, Enhanced Safe Browsing users will benefit from additional protections:

  • Strengthened protections in GMail including additional checks on attachments and web links
  • Tailored protection if an attack is detected on the account

By choosing Enhanced Safe Browsing, users will share additional security-related information in order to improve their online protection. This data is used only for security purposes and deleted after a short period of time. By sharing additional information about potential risky events, Chrome enables Safe Browsing to improve its ability to detect malicious content online, to better protect users all over the web.

API Documentation


Safe Browsing gives users the ability to protect themselves from multiple types of unsafe sites and applications. Our policies help define the types of web threats about which Safe Browsing will notify users and webmasters.


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, where a page tries to steal a user's password or other personal data.
