Benefits of DMARC Monitor for Microsoft 365

Discover third-party services sending on your behalf, as well as potential imposters that are hijacking your brand to send fraudulent email to your customers, partners, and employees - as you!

With 100% visibility, you’ll be armed with all the information you need to work with business stakeholders to determine which services are legitimate and authorized. From there, you’ll be in a position of confidence to move your organization to full DMARC enforcement, where all unauthenticated traffic is blocked.

Automates discovery of third party cloud services legitimately utilizing your domain as well as malicious actors abusing your domain for their own nefarious purposes

  • Eliminates the need for manual analysis of DMARC reports
  • Ensures compliance -- the only solution that doesn’t use personally identifiable information (PII) or protected health information (PHI)
  • Drastically reduces IT time and expense (near-zero FTEs)
  • Fast to deploy - just five minutes to point a DMARC record to the Valimail Cloud
