Security checks — sorted by severity
HSTS Header
Strict-Transport-Security header is missing. Connections can be downgraded to HTTP via man-in-the-middle attacks.

DMARC / Email Security
Strengths: SPF record present with soft-fail (~all). Issues: No DMARC record found — email spoofing is not prevented; No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).

MTA-STS & TLS Reporting
Issues: No MTA-STS configured — email in transit is vulnerable to TLS downgrade attacks. Sending servers cannot verify that your mail server requires TLS; No TLSRPT record — TLS delivery failures won't be reported to domain owner.

DNS CAA Records
No CAA records found. Without CAA, any Certificate Authority can issue certificates for this domain. Adding CAA records restricts issuance to authorized CAs only, reducing the risk of misissued certificates.

security.txt (RFC 9116)
No security.txt found. Publishing a security.txt at /.well-known/security.txt is the industry standard (RFC 9116) for vulnerability disclosure policies. Its absence may indicate a less mature security program.

MX Records & Mail Provider
Strengths: Mail handled by isaac.mx.cloudflare.net; 3 MX record(s) configured; Multiple MX records provide redundancy.

CVE Exposure
Detected technologies: cloudflare. (cloudflare detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.

Certificate Hygiene
Strengths: Certificate valid, 39 days remaining; Issued by Google Trust Services. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.

Recommended actions
1+ items
Steps to improve rx-tx.info's security grade, ranked by impact.
1
Set up email authentication (DMARC, DKIM)
Without email authentication, anyone can send emails that appear to come from rx-tx.info. This is the most common vector for phishing attacks targeting employees and customers. DMARC, DKIM are not configured.
NIST CSFPR.AC-7
Email authentication is a required access control
ISO 27001A.13.2.1
Information transfer policies require email security controls
HIPAA§164.312(e)
Transmission security for electronic PHI
How to fix this
1
Add SPF record to DNS: v=spf1 include:_spf.google.com ~all (adjust for your email provider)
2
Configure DKIM signing with your email provider and publish the public key in DNS
3
Add DMARC record: v=DMARC1; p=quarantine; rua=mailto:[email protected]
4
Monitor DMARC reports for 2–4 weeks, then upgrade policy to p=reject

AI Summary
What this means
rx-tx.info scored 75/100, meeting baseline requirements but with 3 findings that require attention. The vendor can proceed with a remediation timeline agreement.
Critical gaps in: HSTS Header, DMARC / Email Security. Positive signals: MX Records & Mail Provider, TLS Configuration, TLS Protocol Support all passed.
2 action items identified, including 1 critical. The issues are configuration gaps, not architectural problems. A focused remediation effort of 2–5 days could address all findings.
