Basic Security
10/40 (25%)DNSSEC Enabledhigh
DNSSEC protects against DNS spoofing and cache poisoning
→ Enable DNSSEC to protect against DNS spoofing and cache poisoning attacks. Contact your domain registrar to enable DNSSEC.
Multiple Nameservers
Multiple nameservers provide redundancy
Nameserver Diversitylow
Nameservers on different networks improve resilience
→ All nameservers appear to be from the same provider. Consider using nameservers from different providers for better resilience.
Record Security
15/45 (33%)CAA Recordshigh
CAA restricts which CAs can issue certificates
→ Add CAA records to specify which Certificate Authorities are allowed to issue certificates for your domain. Example: 0 issue "letsencrypt.org"
SPF Record
SPF prevents email spoofing
DMARC Recordcritical
DMARC protects against phishing
→ Add a DMARC record at _dmarc.yourdomain.com. Example: v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com
DKIM Presencelow
DKIM can't be verified from public DNS without knowing your provider's selector (records live at selector._domainkey.yourdomain.com)
→ We couldn't verify DKIM from public DNS — this is normal even when DKIM is working. Confirm it's enabled with your email provider.
Advanced Security
10/25 (40%)Mail Server Configurationmedium
