SSL Verification Bypassed

The server's SSL certificate could not be verified. The analysis was completed using insecure mode. Data may be less reliable.

Reason:

Hostname Mismatch - certificate is issued for *.blob.core.windows.net, *.bn1prdstr14a.store.core.windows.net, *.blob.storage.azure.net, *.z1.blob.storage.azure.net, *.z2.blob.storage.azure.net, *.z3.blob.storage.azure.net, *.z4.blob.storage.azure.net, *.z5.blob.storage.azure.net, *.z6.blob.storage.azure.net, not for images.flashgrade.com

Security Configuration

TLS Protocols
TLS 1.0 TLS 1.1 TLS 1.2 TLS 1.3
Forward Secrecy
Supported (Modern clients use PFS)
Warnings
  • • TLS 1.1 is deprecated and should be disabled
  • • TLS 1.0 is deprecated and should be disabled

Recommendations
  • • Add Strict-Transport-Security header with max-age of at least 1 year
  • • Add Content-Security-Policy header to prevent XSS attacks
  • • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
  • • Add X-Content-Type-Options: nosniff
  • • Add Referrer-Policy header (recommended: strict-origin-when-cross-origin)
  • • Consider adding Permissions-Policy to control browser features

CAA Records (Certificate Authority Authorization)

CAA Records
Not Configured (Any CA can issue certificates)
CAA Issues
  • • No CAA records configured - any CA can issue certificates
Recommendations
  • • Implement CAA records to restrict which CAs can issue certificates for your domain
  • • This adds an extra layer of security against unauthorized certificate issuance
  • • Example: Add CAA record 'example.com. CAA 0 issue "letsencrypt.org"'
  • • Consider adding 'iodef' record to receive security incident reports
