SSL/TLS Protocol Compatibility Matrix

Check which SSL/TLS protocols are supported by a server

Protocol Support

About

The Protocol Support Matrix provides a comprehensive view of which TLS and SSL protocol versions are supported across your entire server infrastructure. It creates a matrix view showing protocol support status for each server, making it easy to identify inconsistencies.

This matrix view is essential for organizations managing multiple servers, as it highlights configuration differences that could indicate security gaps or compatibility issues.

How to Use

  1. 1Enter multiple server addresses (domain:port), one per line
  2. 2Click "Generate Matrix" to test protocol support on all servers simultaneously
  3. 3Review the matrix showing support status for each protocol version on each server
  4. 4Identify and address any servers with unsupported or deprecated protocol configurations

Use Cases

  • •Infrastructure Audit: Get a complete view of protocol support across all TLS endpoints
  • •Consistency Check: Identify servers with different protocol configurations that should be uniform
  • •Hardening Validation:** Confirm that deprecated protocols are disabled on all servers
  • •Compliance Reporting:** Generate protocol support evidence for compliance auditors
  • •Migration Tracking:** Monitor protocol configuration changes during security hardening projects

Tips & Best Practices

  • •Aim for consistent TLS 1.2/1.3 support across all servers
  • •Flag any server still supporting SSL 3.0, TLS 1.0, or TLS 1.1 for immediate remediation
  • •Use the matrix to establish a baseline and track changes over time
  • •Export the matrix for regular compliance reporting

Technical Details

●Protocols: SSL 2.0, SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, TLS 1.3 support testing
●Capacity: Up to 50 servers per matrix generation
●Matrix: Visual table with color-coded support status
●Export: CSV and JSON export for compliance documentation

Frequently Asked Questions

The protocol matrix supports up to 50 servers per operation. For larger infrastructure, generate multiple matrices and combine the results. The export functionality allows combining results from multiple matrix operations.
Green indicates the protocol is supported and should be supported (TLS 1.2/1.3). Yellow indicates the protocol is supported but may pose security risks (TLS 1.1). Red indicates the protocol is supported but should be disabled (SSL 3.0, TLS 1.0). Gray indicates the protocol is correctly disabled.
Yes, matrix results are stored in your scan history. You can compare current results with previous matrices to track protocol configuration changes and demonstrate compliance over time.
