An official member and one of only two DMARC providers in the Microsoft Intelligent Security Association (MISA), Red Sift OnDMARC protects Microsoft 365 customers from phishing attacks and streams authentication telemetry into Microsoft Sentinel.
Red Sift OnDMARC provides Microsoft 365 customers full DMARC protection in 6-8 weeks.
Get daily aggregate DMARC reports for Microsoft 365 and other services that allow you to flag sending sources that have not been surfaced in your standard reports.
Detect who has attempted to impersonate your domain in order to identify what level of threat your business is experiencing and block untrusted and unauthenticated spoofing attacks.
Microsoft now requires SPF, DKIM and DMARC for bulk senders to deliver their mail to Microsoft consumer environments, and OnDMARC is the easiest solution for compliance.
How Red Sift OnDMARC enhances Microsoft 365
Microsoft Defender for Office 365 is a strong first line of defense, filtering spam and blocking threats like known malicious URLs or blacklisted IPs.
Red Sift OnDMARC adds proactive spoofing protection to your Microsoft 365 setup, providing full visibility into your domain’s sender activity, helping prevent brand impersonation and protecting customers and partners from Business Email Compromise (BEC).

Stream DMARC forensics into Microsoft Sentinel
Red Sift OnDMARC brings real-time DMARC data like SPF and DKIM results and audit logs directly into your Microsoft Sentinel workspace for faster triage.
Once there, the events behave like the rest of your data sources. The security operations center (SOC) team can write detection rules against them, correlate them with different signals, and catch suspicious threat activity the moment it occurs, rather than waiting on a report.
Red Sift OnDMARC customers can activate the integration through the Microsoft Azure Marketplace.
“At Microsoft, we look to build enduring, ongoing relationships with partners like Red Sift protecting email and other hybrid work essentials. With increasingly sophisticated cyber criminals targeting email communications, the Red Sift platform helps Microsoft 365 customers to enhance the security of their systems.”
