TLS Versions Probe

Test which TLS protocol versions a server supports by attempting connections with different TLS version constraints. Identify deprecated versions and assess overall TLS security posture.

Understanding TLS Versions

TLS Version Security

  • TLS 1.3: Latest version with improved security and performance
  • TLS 1.2: Widely supported, secure when properly configured
  • TLS 1.1: Deprecated, should not be used
  • TLS 1.0: Deprecated, contains security vulnerabilities

Best Practices

  • Enable TLS 1.2 and 1.3 only
  • Disable deprecated versions (TLS 1.0, 1.1)
  • Regularly update TLS implementations
  • Use strong cipher suites

Compliance Requirements

Many compliance standards (PCI DSS, HIPAA) require disabling deprecated TLS versions. Check your specific requirements.
