Security checks
Each check inspects a different part of apollo.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
DNS Configuration
Strengths: 4 nameservers configured (pdns87.ultradns.net., pdns87.ultradns.org., pdns87.ultradns.biz., pdns87.ultradns.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=31536000 with includeSubDomains and preload. Meets best-practice configuration.
Security Headers
All 5 recommended security headers present: CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy.
CVE Exposure
No server software versions detected in HTTP response headers. This is good practice (version hiding) but means CVE exposure cannot be assessed from external signals alone.
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).
Certificate Hygiene
Strengths: Certificate valid, 147 days remaining; Issued by DigiCert Inc.
