  • Business Email Compromise: How often is your CEO being impersonated over email?
  • Credential Theft: Are your users clicking on websites that are tricking them into giving away their usernames and passwords?
  • Domain Look-Alike Attacks: Are attackers impersonating your brand by registering look-alike / "cousin" domains to trick your users?
  • Business Service Compromise: Are your users receiving convincing emails that impersonate trusted services and senders?
  • Wire Transfer Fraud: Is your finance team receiving email asking for fraudulent money transfers?
  • Authentication Risk: Are internal email services, email marketing, or other "shadow IT" tools leaving you open to email attacks?
