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.

  1. Automates discovery of third party cloud services legitimately utilizing your domain as well as malicious actors abusing your domain for their own nefarious purposes
  2. Eliminates the need for manual analysis of DMARC reports
  3. Ensures compliance -- the only solution that doesn’t use personally identifiable information (PII) or protected health information (PHI)
  4. Drastically reduces IT time and expense (near-zero FTEs)
  5. Fast to deploy - just five minutes to point a DMARC record to the Valimail Cloud





Nope. DMARC Monitor for Microsoft 365 is completely free, with no obligations.

It’s a one time, five minute update on your end. Valimail handles the rest.

Unlike other companies in the space, Valimail does not have access to your DNS or any Personally Identifiable Information. This means zero risk of email downtime, impact on email flow, or PII/PHI leakage.

Email authentication ensures the integrity of your email domain name. With authenticated email, you know that the sender of an email is truly who they say they are. Without it, your executives, employees, customers, and brand, are unprotected against dangerous phishing and impersonation attacks.

Domain-based Message Authentication, Reporting and Conformance (DMARC) is the widely-accepted open technical standard used for email authentication.

DMARC Monitor for Microsoft 365 is the first step to email authentication using the DMARC standard, providing an eye-opening view of all authorized and unauthorized senders sending on your domain. The next step is DMARC enforcement. You can attempt this yourself, and will need to dedicate significant time to getting it right, or you can get fully automated with Valimail Enforce.
