AI-Generated Summary
What this means
rx-tx.info scored 70/100, meeting baseline requirements but with 4 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, DNS Configuration all passed.
3 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.

Security checks
Each check inspects a different part of rx-tx.info's public security setup. Green means healthy, yellow needs attention, red is a problem.
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.
Certificate Hygiene
Strengths: Certificate valid, 65 days remaining; Issued by Google Trust Services; 121 certificates logged in CT. Issues: Certificates issued by 6 different CAs (threshold: 5 for 121 logged certs) — possible misconfiguration or shadow IT. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.
MX Records & Mail Provider
Strengths: Mail handled by isaac.mx.cloudflare.net; 3 MX record(s) configured; Multiple MX records provide redundancy.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
DNS Configuration
Strengths: 2 nameservers configured (robert.ns.cloudflare.com., clarissa.ns.cloudflare.com.); 3 MX records present; DNSSEC enabled; Zone transfers properly restricted.
Security Headers
4/5 security headers present. Missing: CSP.
TLS Protocol Support
Strengths: TLS 1.3 supported; TLS 1.2 supported; TLS 1.3 supported (strongest). Protocol support: TLS 1.3: Yes, TLS 1.2: Yes, TLS 1.1: No, TLS 1.0: No.
Cookie Security
No cookies set on the homepage response. No cookie security flags to evaluate.
Known Breaches
No known breaches found in public disclosure databases.
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.
Recommended actions
3 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.
Compliance impact
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

2
Enable HSTS (HTTP Strict Transport Security)
The HSTS header is missing on rx-tx.info. Without it, connections can be downgraded from HTTPS to HTTP via man-in-the-middle attacks. This is a straightforward server configuration change.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Required application security controls
NIST 800-53SC-8
Transmission confidentiality and integrity
How to fix this
1
Add header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
2
Verify all subdomains support HTTPS before adding includeSubDomains
3
Test with: curl -sI https://rx-tx.info | grep -i strict
4
Submit to hstspreload.org after confirming the header is correct
3
Review certificate configuration
Certificate issues found for rx-tx.info: wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. These are operational hygiene items, not immediate security risks.
How to fix this
1
Consider replacing wildcard cert with individual certs for critical subdomains
2
Consolidate certificate issuance to 1–2 trusted CAs
