This section is mandatory to ensure attack simulation emails can be successfully delivered to your end-users. The following instructions are for Google Workspace (Gmail).
Whitelist OutThink Email Servers
The following IP Addresses must be whitelisted to bypass spam filtering within your organization. OutThink will send attack simulations from these servers.
147.253.222.115199.15.227.83
If your organisation employs an endpoint security device or other gateway which processes all incoming email, the origin IP Addresses of OutThink’s mail servers may not be detected. In this case, it is recommended to whitelist all sender email addresses used by OutThink’s Phishing Simulations instead, as detailed here.
For Google Workspace customers, whitelisting can be achieved as follows. Refer to the Google documentation for further details.
- Login to the Google Admin Console via https://admin.google.com/.
- Navigate to Apps > Google Workspace > Gmail in the side menu.
- Select the Spam, Phishing and Malware options.
- In the Email allowlist, enter all IP Addresses listed at the start of this article, separated by a comma.
- Click Save at the bottom of the screen.
