Email domain security (SPF, DKIM, DMARC) monitoring

What it is

SPF, DKIM, and DMARC are DNS records that help prevent email spoofing and phishing. SPF and DKIM authenticate senders; DMARC tells receivers what to do with failing messages. Monitoring checks that these records exist and are correctly configured.

Why it matters

Missing or weak SPF/DKIM/DMARC makes it easier for attackers to send email that appears to come from your domain (phishing, BEC). Proper configuration protects your brand and recipients. Monitoring catches misconfigurations and expiry.

How Barrion checks it

Barrion performs DNS lookups for your domain's SPF, DKIM (selector), and DMARC records. We validate syntax, alignment, and policy strength. We report missing records, syntax errors, and overly permissive policies. Checks are read-only DNS queries.
