Security checks
Each check inspects a different part of strongintro.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
Security Headers
Only 1/5 security headers present. Missing: X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy. This exposes the application to clickjacking, MIME-sniffing, and other client-side attacks.
DNS Configuration
Strengths: 2 nameservers configured (ns72.domaincontrol.com., ns71.domaincontrol.com.); 2 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Known Breaches
No known breaches found in public disclosure databases.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_128_GCM_SHA256 (128-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
HSTS Header
HSTS enabled: max-age=63072000 with includeSubDomains and preload. Meets best-practice configuration.
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with hard-fail (-all). Issues: No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).
CVE Exposure
