Whitelisting PhishGuard by IP Address in Google Workspace/Google Apps
This setting is recommended if you do not have a cloud-based spam filter in front of Google Workspace. If you do have a cloud-based spam filter, you should whitelist us by our
IP addresses in the filter, and whitelist by header in Google Workspace.
This process of whitelisting accomplished in two steps:
- Add the IP addresses to Email Whitelist
- Add the IP addresses as Inbound Gateways
Add the IP addresses to Email Whitelist
Below are instructions on how to set up your IP allow list for Google Workspace/Google Apps.
- Log in to https://admin.google.com and select Apps.

- Select Google Workspace.

- Select Gmail.

- Select Spam, Phishing and Malware.
- Under the Organizational Unit section, highlight your domain. Do not select an organizational unit (OU). *Note: Google Workspace does not allow whitelisting by IP Address for individual OUs, only the entire domain.

- In the Email whitelist section, enter our IP addresses separated by commas.

- Click Save.
Add PhishGuard IP addresses as Inbound Gateways
This method of whitelisting is to prevent the following Google banners from appearing in your user's inbox when they receive a simulated phishing test from PhishGuard:

Be careful with this message
It was proven that this process exempts simulated phishing emails from the Gmail banner warnings.
- Log in to your Google Admin Console.
- Navigate to Apps > Google Workspace > Gmail > Spam, Phishing and Malware.
- Under Organizational Unit, select your top-level organization (typically your primary domain) on the left.
- Scroll down to the Inbound Gateway setting. Click the setting and check the Enable checkbox. This will open the Inbound gateway screen.
- Configure the Inbound gateway using the settings below:
