Yes, that’s correct. Geekflare has two SSL/TLS-related tools.

TLS Testing Find out quickly the TLS protocol is compatible. It is clear that the program has the capability to test the most current Version of TLS 1.3. 

The TLS scanner Tests in-depth to discover the commonly-found vulnerabilities and common mistakes.

The result is as follows.

  • Supported protocol and their version
  • The server determines the handshake preference.
  • Vulnerability tests include heart bleed or Ticketbleed ROBOT and CRIME. RC4, LUCKY13, BEAST, LOGJAM, DROWN,  POODLE, BREACH and numerous others.
  • Certificate details

Geekflare TLS scanner could be an ideal replacement for SSL Labs.
