Email Security Check
Instantly analyze your domain's SPF and DMARC records. Find out if attackers can spoof your email.
What do these checks mean?
What is SPF?
Sender Policy Framework (SPF) is a DNS record that lists which mail servers are authorized to send email for your domain. It helps prevent basic spoofing.
What is DMARC?
Domain-based Message Authentication (DMARC) tells receiving servers what to do when an email fails SPF/DKIM checks: nothing (none), quarantine it, or reject it.
I have both. Am I safe?
From domain spoofing, yes. But 90% of BEC attacks use legitimate accounts or look-alike domains that pass every DNS check. You need content-level analysis to catch those.
How does MatrixSentry help?
MatrixSentry analyzes email content, sender behavior, and intent using AI. It catches threats that DNS records were never designed to stop.
