Security checks
Each check inspects a different part of thingtesting.com'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.
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.
DNS Configuration
Strengths: 2 nameservers configured (mimi.ns.cloudflare.com., porter.ns.cloudflare.com.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
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 Google Workspace; 5 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.
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.
Security Headers
4/5 security headers present. Missing: CSP.
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.
DMARC / Email Security
Strengths: DMARC policy set to quarantine; SPF record present with soft-fail (~all); DKIM configured (selectors: google, s1, s2, k1).
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, 74 days remaining; Issued by Google Trust Services; 552 certificates logged in CT; Certificates from 6 CAs: "CloudFlare, "Cloudflare, Google Trust Services. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.
Recommended actions
2 items
Steps to improve thingtesting.com's security grade, ranked by impact.
1
Enable HSTS (HTTP Strict Transport Security)
The HSTS header is missing on thingtesting.com. 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://thingtesting.com | grep -i strict
4
Submit to hstspreload.org after confirming the header is correct

2
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for thingtesting.com can be spoofed, potentially redirecting users to malicious sites. This requires coordination with your domain registrar to publish DS records.
Compliance impact
NIST 800-53SC-20
Secure name/address resolution service
How to fix this
1
Check if your DNS provider supports DNSSEC (Cloudflare, Route53, etc.)
2
Enable DNSSEC signing in your DNS provider dashboard
3
Add the DS record to your registrar for .com TLD
4
Verify: dig +dnssec thingtesting.com
