Security Analysis

B
165 / 215
2 high
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 4 nameservers are run by one operator (Amazon Route 53). If it has an outage, the domain stops resolving; a second DNS provider protects against that.
Record Security
30/45 (67%)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 Record
DMARC protects against phishing
DKIM Presencenot checked
No DKIM key at the common selectors we try (default, google, selector1, selector2, k1, s1 and others). Many senders use their own selector names, so DKIM may still be set up. Not scored.
→ If this domain sends mail, look up the selector your email provider gave you with the DKIM checker (/dkim-checker).
Advanced Security
20/25 (80%)Mail Server Configuration
Multiple MX records provide email redundancy
SOA Record Configuration
SOA timers that do not delay new names or expire secondaries (refresh 2h, retry 15m, expire 14d, SOA minimum 1d)
IPv6 Supportlow
AAAA records enable IPv6 connectivity
→ No IPv6 (AAAA) records found. Consider adding IPv6 support for future-proofing.
