What is TLS ?
Transport Layer Security (TLS) is a protocol (connection) that ensures privacy in your communication with Saxo Bank over the Internet.
When a Saxo Bank server and client communicate, TLS ensures that no third party may eavesdrop or tamper with any message.
TLS is the successor to the Secure Sockets Layer (SSL). For a Saxo Trader ‘TCP with TLS’ connection, port 1001 must be open in your firewall/proxy server.
