Documentation: The Email Security Command Center
SentraDMARC is an enterprise-grade email security platform that automates the enforcement of DMARC, SPF, and DKIM protocols via a CNAME-First delegation strategy. It protects domain reputation by blocking unauthorized senders and ensuring legitimate email delivery through real-time transport-layer encryption (MTA-STS) and brand verification (BIMI).
Active Visibility Engine
Unlike legacy monitoring tools, our platform actively interprets aggregate reports to surface spoofing attempts, misconfigurations, and "Shadow IT" senders in real-time. This approach transforms passive XML data into an active, automated defense perimeter.
