Splashtop Gateway allows Team Owner to configure which TLS versions are supported for client and browser connections. You can choose between two options, depending on your security requirements and compatibility needs.
Log into Gateway's management console as Team Owner, go to System > Security > TLS Settings
Option 1: TLS 1.2 and above (Recommended)
-
Provides modern security standards.
-
Ensures compliance with current industry and regulatory requirements.
-
Only endpoints or browsers that support TLS 1.2 or higher can connect.
-
Recommended for most deployments where security is the priority.
Option 2: TLS 1.0 / 1.1 and above
-
Allows connections from older Splashtop endpoints or browsers that require TLS 1.0 or 1.1.
-
Maintains backward compatibility with legacy environments.
-
Higher TLS versions (1.2 and 1.3) remain supported, but this option is less secure than enforcing TLS 1.2+.
