Security checks
Each check inspects a different part of tesorio.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
Security Headers
Only 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.
DNS Configuration
Strengths: 4 nameservers configured (ns-1332.awsdns-38.org., ns-141.awsdns-17.com., ns-1695.awsdns-19.co.uk., ns-777.awsdns-33.net.); 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 (2592000s). Recommended minimum: 15768000 (6 months).
Certificate Hygiene
Strengths: Certificate valid, 85 days remaining; Issued by Let's Encrypt. Issues: Wildcard certificate in use — broader attack surface if compromised.
Known Breaches
No known breaches found in public disclosure databases.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
DMARC / Email Security
Strengths: DMARC policy set to quarantine; SPF record present with hard-fail (-all); DKIM configured (selectors: google, s1, s2, smtpapi). Issues: DMARC has no aggregate report URI (rua).
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.
Recommended actions
4 items
Steps to improve tesorio.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 tesorio.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 Content-Security-Policy header (start with report-only to avoid breakage)
2
Add: X-Frame-Options: DENY (or SAMEORIGIN if you use iframes)
3
Add: Referrer-Policy: strict-origin-when-cross-origin
4
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
5
Verify with: curl -sI https://tesorio.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'

2
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for tesorio.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 tesorio.com
3
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://tesorio.com | grep -i strict
4
Review certificate configuration
Certificate issues found for tesorio.com: 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
