Whitelisting Dune Security in Netskope

Ensure Dune’s phishing simulation and training emails are properly delivered.

This guide will help you whitelist Dune Security’s phishing URLs in Netskope. You will create a Custom URL list to ensure Dune’s phishing simulation and training emails are properly delivered, bypassing Netskope's default filtering.

Step 1: Create a Custom URL List

  1. Navigate to Policies: Go to Policies > Web > URL Lists.
  2. Create a New URL List:
    • Click New URL List.
    • Name the list: DuneSecurity_CustomURLList.
  3. Add the Following URLs: In the URL & IP Address field, enter the following domains:
    markdown
     
    *.enterprise-support-desk.com
    *.action-required.com
    *.it-servicenow.net
    *.executive-mailsend.com
    *.digital365-outlook.com
    *.central-comms.com
    *.enterprise-staff-portal.com
    *.hr-notifications.com
    *.access-documents.com
    *.shipping-365.com
    *.enterprise-notification.com
    *.rewardstore24.com
    *.compliance-verification.com
    *.notify-360.com
    *.notify-outlook.com
    *.mailsend365.com
    *.system-notify.com
    *.enterprise-help-desk.com
    *.send-survey.com
    *.employee-support.org
    *.direct-notification.com
    *.internal-it-support.com
    *.enterprise-it-helpdesk.com
    *.corporate-account.com
    *.corporate-gmail.com
    *.sharepoint-fileshare.com
    *.privacy-postoffice.com
    *.compliance-network.com
    *.hr-notify.com
  4. Save: Click Save.
  5. Apply Changes: Click Apply Changes to implement the changes immediately.

Step 2: Create a Steering Exception (if needed)

If the custom URL list does not work, you can create a Steering Exception.

  1. Navigate to Steering Configuration:
    • Go to Settings > Cloud Security Platform > Steering Configuration.
    • Click on the default tenant steering configuration or any other applicable configuration.
  2. Add a New Exception:
    • Click on the Exceptions tab.
    • Click New Exception.
    • Add the same list of domains from Step 1 to bypass filtering for emails from Dune Security.
  3. Save and Apply: Save the exception and apply the changes to ensure proper email deliverability.

Following these steps will ensure that Dune Security’s emails and phishing simulations are not blocked by Netskope’s security filters​​​.
