What Zone Intelligence Checks
Validates your Sender Policy Framework record to prevent email spoofing and phishing attacks sent from your domain.
Checks for DomainKeys Identified Mail signing, which cryptographically authenticates outbound email and reduces spoofing risk.
Evaluates your DMARC policy enforcement level. A 'reject' policy provides the strongest protection against domain abuse.
Confirms mail exchange records are properly configured so inbound email reaches your organization reliably.
Verifies your domain serves traffic over HTTPS with a valid TLS certificate, protecting data in transit.
Checks for Brand Indicators for Message Identification, which displays your logo in supported email clients and signals strong email authentication.
