Identity Findings
No SPF record found
The domain has no SPF record, allowing anyone to send email as this domain.
💡 Publish an SPF TXT record (e.g. "v=spf1 include:_spf.google.com -all").
No MX records found
The domain has no MX records and cannot receive email.
💡 Publish MX records pointing to your mail server(s).
No DKIM records found
No DKIM records were found for any common selector. Email may not be authenticated.
💡 Configure DKIM signing and publish the public key at <selector>._domainkey.caterpillar.com
NS delegation mismatch
The registrar-delegated nameservers do not match the zone NS records.
💡 Update either the registrar NS delegation or the zone NS records to match.
Inconsistent DNS responses across nameservers
Authoritative nameservers return different answers for the same query.
💡 Verify zone transfers are working correctly and all nameservers serve the same zone data.
No MTA-STS record found
Without MTA-STS, mail transport encryption cannot be enforced and is vulnerable to downgrade attacks.
💡 Publish a _mta-sts TXT record and host a policy file at https://mta-sts.caterpillar.com/.well-known/mta-sts.txt
No TLS-RPT record found
Without TLS-RPT, you will not receive reports about TLS negotiation failures.
💡 Publish a _smtp._tls TXT record (e.g. "v=TLSRPTv1; rua=mailto:tls-reports@caterpillar.com").
ARC check skipped — no MX records
Cannot assess ARC support without MX records.
No CAA iodef tag configured
No iodef tag is present in the CAA records. CA policy violation reports will not be sent.
💡 Add an iodef CAA record. Example: 0 iodef "mailto:security@example.com"
Very low TTL on A record: 18s
The A record has a TTL of 18s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
Very low TTL on AAAA records: 18s
2 AAAA records have a TTL of 18s or less (below 300s).
💡 Increase the TTL to at least 300 seconds unless frequent changes are expected.
NS TTL mismatch between parent and authoritative zone
The NS record TTL in the parent zone (~7194s) differs significantly from the authoritative zone (~86400s).
💡 Align NS record TTLs between the parent zone delegation and the authoritative zone.
DKIM cryptographic configuration is compliant
No RFC 8301 compliance issues detected in DKIM key configuration.
No deprecated DMARCbis tags present
The DMARC record does not use any tags deprecated in DMARCbis (pct, rf, ri).
IPv6 readiness is good
IPv6 records are present and properly configured.
DKIM2 not detected
No DKIM key record with v=2 was found across common selectors. DKIM2 is an emerging standard and not yet widely deployed.
DMARC alignment: adkim=r, aspf=r
DKIM alignment is relaxed, SPF alignment is relaxed.
DMARC failure reporting: fo=1
Failure reports generated when any authentication mechanism fails.
DMARCbis np tag absent
The DMARC record does not include the np (non-existent subdomain policy) tag. Consider adding np=reject to protect non-existent subdomains under DMARCbis.
DMARCbis psd tag absent
The DMARC record does not include the psd (public suffix domain) indicator. Consider adding psd=n to explicitly identify this as an organizational domain.
DANE check skipped — no MX records
Cannot check DANE/TLSA without MX records.
No BIMI record found
BIMI is not configured. Your brand logo will not display in supporting email clients.
Open relay check skipped — no MX records
Cannot test for open relay without MX records.
SMTP compliance check skipped — no MX records
Cannot test SMTP compliance without MX records.
Port exposure check skipped — no MX records
Cannot scan ports without MX records.
STARTTLS downgrade check skipped — no MX records
Cannot test STARTTLS without MX records.
RFC 8058 one-click unsubscribe assessment
No DKIM signing detected. RFC 8058 one-click unsubscribe requires DKIM-signed List-Unsubscribe headers.
FCrDNS check skipped — no MX records
Cannot perform FCrDNS without MX records.
SOA record parameters
Serial: 1652272891, Refresh: 3600s, Retry: 600s, Expire: 604800s, Min TTL: 1800s
Authorized certificate authorities
CAA records restrict certificate issuance to: www.digicert.com, letsencrypt.org, pki.goog, amazon.com, amazontrust.com, awstrust.com, amazonaws.com
Attack Surface Findings
Domain enumerability: medium
The domain has moderate enumerability. CT logs and DNS records reveal significant information about the domain structure.
💡 Restrict zone transfers, use NSEC3 instead of NSEC, consider wildcard certificates to reduce CT log exposure, and implement rate limiting on DNS queries.
DNSSEC is not enabled
No DNSKEY or DS records were found. DNS responses are not cryptographically authenticated.
💡 Enable DNSSEC by generating DNSKEY records and publishing DS records at the registrar.
No internal information leakage detected
No non-routable IP addresses or internal references were found in public DNS records.
No excessive DNS information exposure detected
No HINFO, LOC, RP records, version disclosures, or zone walking vulnerabilities were found.
No email autodiscovery endpoints detected
No Microsoft Autodiscover, Mozilla Autoconfig, or email SRV records were found.
1 subdomain(s) discovered for caterpillar.com
Subdomains were enumerated via Certificate Transparency logs, DNS wordlist brute-forcing, and DNS record analysis.
0 certificate(s) found in CT logs
Certificate Transparency logs contain 0 certificate(s) for caterpillar.com and its subdomains. Each certificate reveals subdomain names.

Dependency Chains
DMARC Authentication Chain (SPF)
DMARC uses SPF to verify that emails come from authorized servers
SPF Record
SPF record missing
→
DMARC Policy
DMARC policy: reject
⚠️ SPF record is missing. DMARC relies on SPF to verify sender authorization. Without SPF, DMARC alignment will fail, reducing email deliverability and brand protection.
DMARC Authentication Chain (DKIM)
DMARC uses DKIM to verify that emails have not been tampered with
DKIM Signature
DKIM signature missing
→
DMARC Policy
DMARC policy: reject
⚠️ DKIM signature is missing. DMARC relies on DKIM to verify email integrity and prevent tampering. Without DKIM, DMARC alignment will fail for cryptographic verification.
Enforced Encryption Chain
MTA-STS enforces TLS encryption to prevent man-in-the-middle attacks
TLS Support
TLS not verified or unsupported
→
MTA-STS Policy
MTA-STS not configured
⚠️ TLS support could not be verified. MTA-STS requires TLS to enforce encrypted connections. Without TLS, MTA-STS cannot function.
Brand Identity Chain
BIMI displays your logo in email clients, but requires DMARC enforcement
DMARC Enforcement
DMARC policy: reject
→
BIMI Record
BIMI not configured
⚠️ BIMI record is missing. Even with DMARC enforcement, you need to configure BIMI to display your brand logo in supported email clients.
TLS Monitoring Chain
TLS-RPT provides reports about TLS connection failures
TLS Support
TLS not verified or unsupported
→
TLS-RPT Reporting
TLS-RPT not configured
⚠️ TLS support could not be verified. TLS-RPT reports on TLS connection failures, but without TLS support, there's nothing to monitor. You need working TLS encryption before TLS-RPT can provide value.
