    Customer-operated Tunnel Server

    For customers looking for a reliable and convenient solution, SEGGER provides a powerful, high-performance tunnel server infrastructure free of charge. Designed to handle thousands of simultaneous connections, the SEGGER-operated tunnel server enables seamless remote access to J-Link devices worldwide.

    For enterprises with specific IT security policies, compliance requirements, or a preference for complete infrastructure independence, SEGGER offers an additional option: Operate your own J-Link Tunnel Server.

    By hosting the tunnel server within your own IT infrastructure, companies gain full control over their remote debug connections while maintaining the proven functionality and reliability of SEGGER's J-Link technology. The customer-operated J-Link Tunnel Server works in conjunction with the J-Link Remote Server, which is required to establish the connection between the J-Link debug probe and the tunnel server.
