Spoof emails can be difficult to spot.
They look real, because they appear to use a genuine email address, and are used to instigate phishing attacks, distribute malware or obtain access to confidential or sensitive data – risking business continuity, profitability, and brand reputation.
Without DMARC, spoofers can send emails that appear to originate from your domain. They do this by falsifying the ‘from’ address that’s visible to the reader.
What is DMARC?
DMARC is the email protocol that verifies the authenticity of messages sent by your company’s authorized servers, helping to prevent unauthorized senders from impersonating your email domains. This also improves delivery rates for your genuine emails, reducing their chances of being marked as spam. DMARC monitors email traffic and identifies potential spoofing threats, telling you which emails passed or failed the authentication checks, and which IP addresses were used.
