Security checks

Each check inspects a different part of nhg.com.sg's public security setup. Green means healthy, yellow needs attention, red is a problem.

DMARC / Email Security
Strengths: DMARC policy set to quarantine; SPF record present with hard-fail (-all). Issues: No DKIM records found for common selectors (may use non-standard selectors).
Needs work
DNS Configuration
Strengths: 2 nameservers configured (bart.ns.cloudflare.com., teresa.ns.cloudflare.com.); 2 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Needs work
Certificate Hygiene
Strengths: Certificate valid, 84 days remaining; Issued by Google Trust Services. Issues: Wildcard certificate in use — broader attack surface if compromised.
Needs work
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Healthy
Known Breaches
No known breaches found in public disclosure databases.
Healthy
HSTS Header
HSTS enabled: max-age=31536000 with includeSubDomains and preload. Meets best-practice configuration.
Healthy
Security Headers
All 5 recommended security headers present: CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy.
Healthy
CVE Exposure
Detected technologies: Vercel. (Vercel detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.
Healthy

Steps to improve nhg.com.sg's security grade, ranked by impact.

1
Strengthen email authentication configuration
Impact: 2–4 Hours
HIGH
Email authentication is partially configured for nhg.com.sg but has gaps. Actions needed: configure DKIM. Until DMARC enforcement is active, spoofed emails may still reach recipients.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
How to fix this
1
Configure DKIM and publish public key in DNS
2
Verify with: nslookup -type=txt _dmarc.nhg.com.sg
2
Enable DNSSEC on your domain
Impact: 1–3 Days (Depends On Registrar)
MEDIUM
Without DNSSEC, DNS responses for nhg.com.sg 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 .sg TLD
4
Verify: dig +dnssec nhg.com.sg
3
Review certificate configuration
Impact: 1–2 Hours
LOW
Certificate issues found for nhg.com.sg: 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
