Allow-Listing in ProofPoint (aka: safe-listing, white-listing)

Proofpoint Allow-Listing

If you’re using Proofpoint’s spam filtering software, you can safelist (whitelist) CyberHoot to allow your users to receive our simulated attack-based phish testing emails.

Allow-Listing By IP Address (preferred)

  1. From your Proofpoint admin center, navigate to Email Firewall, then Rules.
  2. Be sure to select the On radio button for Enable, under Rule Settings.
  3. Name your rule ID something descriptive, such as “CyberHoot Allow-Listing by IP Address,” and provide a summary of the rule such as “Enable Attack-Based Phish Testing for CyberHoot Sending Mail servers” 
  4. In the “Conditions” section you will allow list CyberHoot by IP address using the “Add Condition” button. You can find our IP addresses for phishing and training emails in this article or find them at the end of this article below.
  5. Under “Dispositions”, change the Delivery Method from the default selection to Deliver Now.
  6. Be sure to save your rule and allow time for this new setting to propagate before testing.

Please Note:  if you are using URL Defense in your ProofPoint, be sure to also enable a bypass for CyberHoot in URL defenses.  See below for details.
