DNS & Email Security Checker
Audit your domain's DNS security configuration: SPF, DKIM, DMARC, DNSSEC, MX records, and more. Identify email spoofing vulnerabilities and DNS misconfigurations.
DNS Records Checked
SPF (Sender Policy Framework)
Verifies which mail servers are authorized to send email on behalf of your domain. Prevents sender address forgery.
DKIM (DomainKeys Identified Mail)
Adds a digital signature to outgoing emails, allowing receivers to verify the message was not altered in transit.
DMARC (Domain-based Message Authentication)
Tells receiving servers how to handle emails that fail SPF and DKIM checks. Critical for protecting your domain reputation.
DNSSEC (DNS Security Extensions)
Adds cryptographic signatures to DNS records, protecting against DNS cache poisoning and spoofing attacks.
MX Records (Mail Exchange)
Verifies mail server configuration and proper DNS resolution for email delivery.
DNS Misconfigurations
Detects common DNS issues including CAA records, TTL values, glue records, and zone transfer configuration.
