Security checks
Each check inspects a different part of paystack.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
DNS Configuration
Strengths: 2 nameservers configured (hope.ns.cloudflare.com., dion.ns.cloudflare.com.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
HSTS Header
HSTS present but max-age is low (15552000s). Recommended minimum: 15768000 (6 months).
Certificate Hygiene
Strengths: Certificate valid, 37 days remaining; Issued by DigiCert Inc. Issues: Wildcard certificate in use — broader attack surface if compromised.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Security Headers
4/5 security headers present. Missing: CSP.
Known Breaches
No known breaches found in public disclosure databases.
DMARC / Email Security
Strengths: DMARC policy set to quarantine; DKIM configured (selectors: google, s1, s2, mandrill). Issues: SPF record uses neutral (?all) — no real enforcement.
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.

Steps to improve paystack.com's security grade, ranked by impact.
1
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for paystack.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 paystack.com

2
Increase HSTS max-age duration
HSTS is enabled but the max-age (0s) is below the recommended minimum of 15768000s (6 months). A short max-age means browsers forget the HTTPS-only policy quickly, reducing protection between visits.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Application security header configuration
How to fix this
1
Update header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
2
Verify: curl -sI https://paystack.com | grep -i strict
3
Review certificate configuration
Certificate issues found for paystack.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
