Understanding DMARC Reports
DMARC Aggregate Reports (RUA) are the heartbeat of email security. They provide a daily, comprehensive view of every server attempting to send email on behalf of your domain.
The Visibility Gap: Most organizations don't know that 30-50% of their email traffic is generated by "Shadow IT" (unapproved 3rd party tools) or potential spoofing attacks. Without DMARC reports, you are flying blind.
What's Inside a Report?
Receivers (like Google, Microsoft, Yahoo) send XML data containing:
- Source IP: Measurements of who sent the email.
- Volume: How many emails were sent.
- Authentication Results: Did SPF pass? Did DKIM pass?
- Alignment Status: Did the sender match your domain?

The SentraDMARC Advantage
Raw XML reports are unreadable to humans. We process them into:
Threat Intelligence
We automatically flag known malicious IPs and geo-locate every sender.
Smart Categorization
We identify vendors (e.g., "Mailchimp", "Salesforce") so you don't have to guess IP addresses.
