The persistent risks to corporate emails are spear phishing and email spoofing.
Monitor, identify and mitigate them with DMARC SONAR.
DMARC allows you to stop fraud by isolating and rejecting illegitimate email directed at your organisation or customers. DMARC makes email easy to identify, and process with email delivery assured. DMARC records instruct receivers to report, reject and quarantine unauthorized use of your email domains.
