Real-Time Threat Telemetry & Defense-in-Depth Diagnostics
Secure every layer of your email infrastructure by executing a rigorous, full-scale analysis of your domain's exact security posture in real-time. Completely bypassing flawed estimations, we execute direct, high-performance DNS queries to strictly evaluate your Anti-Spoofing configurations (identifying enforced DMARC p=reject and SPF -all policies), definitively verify inbound encrypted TLS connections via MTA-STS, and rigorously audit Certificate Authority (CAA) rules to actively prevent rogue SSL issuances. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our robust backend thoroughly assesses your BIMI brand readiness and active reporting telemetry (TLS-RPT/DMARC RUA), ultimately translating highly complex cryptographic DNS configurations into a clear, actionable Executive Security Grade (A+ to F) to flawlessly fortify your defense-in-depth architecture.
Analyze your domain's entire email security posture. We query and score your Anti-Spoofing configurations (DMARC/SPF), Transport Encryption policies (MTA-STS), Infrastructure rules (CAA), and Brand Protection (BIMI) to generate an executive Security Grade.
Modern email infrastructure requires defense-in-depth. A strong DMARC policy won't stop Man-in-the-Middle attacks, and perfect encryption doesn't prevent rogue certificates. Secure every layer.
p=reject policy with -all in SPF yields the highest protection against phishing and domain impersonation.Your feedback has been submitted successfully. We appreciate your help in improving our tools.
