What Is Phishing and How to Prevent It With Google Workspace
If you work with emails, you need to know what phishing is and how to prevent it.
Enable this security setting to protect all users in your Google Workspace from emails coming from domains that are visually similar to your domains.
A sending domain may be almost identical to yours, intended to mislead users into thinking the email is being sent by someone in their company when it’s not.
For example, your domain may be bornwinners.com, and someone may send you an email from bornvvinners.com. If you don’t pay close attention, you may not notice that there’s double V instead of W in the word winners.
Another good example of visually similar characters is lowercase L and uppercase i. They are basically indistinguishable in many fonts.
In the Admin console at https://admin.google.com, click the Apps icon.
Select Google Workspace.
Click Gmail. Make sure not to check the box to the left; just click the service.
Select Safety.
Select Spoofing and authentication.
Check Protect against domain spoofing based on similar domain names.
Under Choose an action, decide what to do with emails caught by this rule:
If you select Quarantine, click Choose a quarantine to select a quarantine to use for this. See how to create and access quarantines here.
After updating, click SAVE at the bottom. Changes may require up to 24 hours to take effect.
