Security checks
Each check inspects a different part of netcraft.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
Security Headers
1/5 security headers present. Missing: CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy. This exposes the application to clickjacking, MIME-sniffing, and other client-side 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
Strengths: CAA records configured (9 record(s)); Authorized CAs: digicert.com; cansignhttpexchanges=yes, amazon.com, letsencrypt.org, globalsign.com, pki.goog, comodoca.com. Issues: No iodef record — CA violations won't be reported to the domain owner.
DNS Configuration
Strengths: 2 nameservers configured (authns2.netcraft.com., authns1.netcraft.com.); 2 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Certificate Hygiene
Strengths: Certificate valid, 55 days remaining; Issued by Google Trust Services; 1256 certificates logged in CT. Issues: Certificates issued by 16 different CAs (threshold: 8 for 1256 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 mail-1a.netcraft.com; 2 MX record(s) configured; Multiple MX records provide redundancy.
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.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
security.txt (RFC 9116)
Strengths: security.txt found with 6 field(s); Contact: https://trust.netcraft.com/#:~:text=Netcraft%20Vulnerability%20Disclosure%20Policy; Expires in 236 days (2026-11-30T12:00:00.000Z); Disclosure policy: https://trust.netcraft.com/#:~:text=Netcraft%20Vulnerability%20Disclosure%20Policy; Canonical URL specified; Preferred languages: en; Security hiring link included. Issues: Not PGP signed (recommended for authenticity).
HSTS Header
HSTS enabled: max-age=31536000s (365 days). Missing includeSubDomains — subdomains not covered. Missing preload directive.
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, Framer/0ea0c8c. (cloudflare detected but excluded from CVE matching — upstream infrastructure). No high or critical CVEs found for detected versions.
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with hard-fail (-all); DKIM configured (selectors: google, selector1).
Recommended actions
3 items
Steps to improve netcraft.com's security grade, ranked by impact.
1
Add missing security headers (CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy)
4 of 5 recommended security headers are missing on netcraft.com: CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy. These headers protect against clickjacking, MIME-sniffing, and unauthorized browser feature access. Adding them is a server configuration change with no application code changes required.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Security headers are required application controls
OWASPSecure Headers
Recommended baseline for web applications
How to fix this
1
Add a Content-Security-Policy header. Safe starting value (works with Google Fonts and inline styles/scripts): default-src 'self'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; font-src 'self' https://fonts.gstatic.com; script-src 'self' 'unsafe-inline'; upgrade-insecure-requests. Test your site after adding it, then tighten over time by removing 'unsafe-inline'.
2
Add: X-Frame-Options: SAMEORIGIN (use DENY only if you never embed your pages in iframes)
3
Add: Referrer-Policy: strict-origin-when-cross-origin
4
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
5
Verify with: curl -sI https://netcraft.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'

2
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for netcraft.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 netcraft.com
3
Review certificate configuration
Certificate issues found for netcraft.com: wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. Ensure auto-renewal is configured to prevent expiry. These are operational hygiene items, not immediate security risks.
How to fix this
1
Verify auto-renewal is configured (Let's Encrypt: certbot renew --dry-run)
2
Consider replacing wildcard cert with individual certs for critical subdomains
3
Consolidate certificate issuance to 1–2 trusted CAs
