Security checks
Each check inspects a different part of lobstertube.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
MTA-STS & TLS Reporting
Issues: No MTA-STS configured — email in transit is vulnerable to TLS downgrade attacks. Sending servers cannot verify that your mail server requires TLS; No TLSRPT record — TLS delivery failures won't be reported to domain owner.
DNS CAA Records
Strengths: CAA records configured (11 record(s)); Authorized CAs: comodoca.com, digicert.com; cansignhttpexchanges=yes, godaddy.com, letsencrypt.org, pki.goog; cansignhttpexchanges=yes, ssl.com. Issues: No iodef record — CA violations won't be reported to the domain owner.
DNS Configuration
Strengths: 2 nameservers configured (deb.ns.cloudflare.com., venkat.ns.cloudflare.com.); Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
security.txt (RFC 9116)
No security.txt found. Publishing a security.txt at /.well-known/security.txt is the industry standard (RFC 9116) for vulnerability disclosure policies. Its absence may indicate a less mature security program.
MX Records & Mail Provider
No MX records found. This domain does not receive email directly — this is intentional for many domains and carries no security risk. If email is expected, verify mail routing via A/AAAA fallback or a mail provider.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
TLS Protocol Support
Strengths: TLS 1.3 supported; TLS 1.2 supported; TLS 1.3 supported (strongest). Protocol support: TLS 1.3: Yes, TLS 1.2: Yes, TLS 1.1: No, TLS 1.0: No.
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with hard-fail (-all). Issues: DMARC has no aggregate report URI (rua); No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).
Known Breaches
No known breaches found in public disclosure databases.
HSTS Header
HSTS enabled: max-age=15768000s (182 days). Missing includeSubDomains — subdomains not covered. Missing preload directive.
Security Headers
4/5 security headers present. Missing: Permissions-Policy.
Cookie Security
Strengths: 2 cookie(s) analyzed; All cookies have Secure flag; All cookies have HttpOnly flag; All cookies have SameSite attribute.
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.
Certificate Hygiene
Strengths: Certificate valid, 45 days remaining; Issued by Google Trust Services; 135 certificates logged in CT; Certificates from 5 CAs: "GoDaddy.com, Google Trust Services, Google Trust Services LLC. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.
Recommended actions
1 item
Steps to improve lobstertube.com's security grade, ranked by impact.
1
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for lobstertube.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 lobstertube.com
