What Requires Attention
No urgent actions detected. Domain security posture is well-maintained.
The BIG Questions
Can this domain be impersonated by email? Not Assessed
Can DNS itself be tampered with? Not Assessed
Can this brand be convincingly faked? Not Assessed
Is mail transport encryption enforced? Not Assessed
Is certificate issuance controlled? Not Assessed

Technical Findings

Email Authentication
SPF (Sender Policy) Configured
DMARC (Policy) Configured Policy: reject
DKIM (Signatures) Not Detected
Mail Posture No-Mail: Partial
Mail Transport Security
MTA-STS Partial
DANE / TLSA Hosted Provider No MX records available — DANE check skipped
TLS-RPT (Reporting) Not Configured
Mail Transport Not Enforced Policy-assessed
DNS Security
DNSSEC Signed & Validated
DNSSEC fully configured and validated — AD (Authenticated Data) flag set by resolver 8.8.8.8 confirming cryptographic chain of trust from root to zone (RFC 4035 §3.2.3)
NS Delegation Healthy
Brand & Certificate Controls
BIMI (Brand Logo) Not Configured
CAA (Certificate) Open Any certificate authority may issue certificates
Priority Actions 5 total Achievable: Low Risk
Medium Deploy MTA-STS policy

Publish an MTA-STS DNS record and host a policy file at https://mta-sts.usa.gov/.well-known/mta-sts.txt. This tells senders to require TLS when delivering mail to your domain.

_mta-sts.usa.gov TXT "v=STSv1; id=20240101"
Low Add CAA records

Publish CAA DNS records to restrict which Certificate Authorities can issue TLS certificates for your domain. Specify your preferred CA (e.g., letsencrypt.org, digicert.com). CAA is advisory — CAs must check it before issuing, but absence means any CA can issue.

usa.gov CAA 0 issue "letsencrypt.org"
Low Configure TLS-RPT reporting

TLS-RPT (TLS Reporting) sends you reports about TLS connection failures when other servers try to deliver mail to your domain. Helps diagnose MTA-STS and STARTTLS issues.

_smtp._tls.usa.gov TXT "v=TLSRPTv1; rua=mailto:tls-reports@usa.gov"
Low Deploy DANE/TLSA for email transport

DNSSEC is already enabled — you can strengthen email transport security by publishing DANE TLSA records. DANE binds your mail server's TLS certificate to DNS, preventing man-in-the-middle attacks on SMTP connections.

_25._tcp.mail.usa.gov TLSA 3 1 1 <certificate_hash>
Low Configure BIMI brand logo

Publish a BIMI DNS record pointing to your brand logo (SVG Tiny PS format). For full support in Gmail, you will also need a Verified Mark Certificate (VMC).

default._bimi.usa.gov TXT "v=BIMI1; l=https://usa.gov/logo.svg"
