Trident has various security protocols in place to filter out emails containing malicious content. From the Zoho Mail web settings, admins can set trusted domains and senders and utilize additional spam controls to prevent malicious emails from reaching an organization's inbox.

Apart from this, Trident displays a warning to prompt users to exercise extra caution in their email correspondence. These alerts are shown in the following circumstances:

• Sending emails to people who aren't a part of your contacts
  

• Receiving emails from a new email address for the first time
  

• Receiving emails with suspicious URLs
