Security checks
Each check inspects a different part of nist.gov's public security setup. Green means healthy, yellow needs attention, red is a problem.
Security Headers
3/5 security headers present. Missing: Referrer-Policy, Permissions-Policy.
Certificate Hygiene
Strengths: Certificate valid, 49 days remaining; Issued by Let's Encrypt. Issues: Wildcard certificate in use — broader attack surface if compromised.
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with hard-fail (-all); DKIM configured (selectors: selector2).
Known Breaches
No known breaches found in public disclosure databases.
DNS Configuration
Strengths: 3 nameservers configured (gold.foundationdns.com., gold.foundationdns.net., gold.foundationdns.org.); 1 MX records present; DNSSEC enabled; Zone transfers properly restricted.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
HSTS Header
HSTS enabled: max-age=31536000. Missing includeSubDomains. Missing preload directive.
CVE Exposure
Detected technologies: cloudflare, Proxy/CDN. (cloudflare, Proxy/CDN detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.

Steps to improve nist.gov's security grade, ranked by impact.
1
Add optional security headers (Referrer-Policy, Permissions-Policy)
nist.gov has most security headers configured. Missing: Referrer-Policy, Permissions-Policy. These are best-practice additions that reduce the attack surface for client-side vulnerabilities.
How to fix this
1
Add: Referrer-Policy: strict-origin-when-cross-origin
2
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
3
Verify with: curl -sI https://nist.gov | grep -iE 'content-security|x-frame|x-content|referrer|permissions'

2
Review certificate configuration
Certificate issues found for nist.gov: 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
