Trusted domains

Email Security allows you to exempt known partner and internal domains from typical detection scanning. Adding trusted domains helps to reduce false positives on malicious, suspicious, and spoof dispositions.

To configure a trusted domain:

  1. Log in to Zero Trust ↗.
  2. Select Email Security.
  3. Select Settings, go to Detection settings > Trusted domains.
  4. On the Detection settings page, select Add a domain.
  5. Select the Input method: Choose between Manual input, and Upload trusted domain list:
    • Manual input:
      • Domain info: Enter a valid domain name.
      • Domain type: Select one or both options:
        • Proximity domain: Domains with similar spelling to your existing domain.
        • Recent domain: Domains created recently.
      • Notes: Provide additional information about the trusted domain list.
    • Upload trusted domain list: You can upload a file no larger than 150 KB of multiple trusted domains. The file can only contain Domain, Notes, Proximity and Recent fields. The first row must be a header row.
  6. Select Save.
