If the SSH (Secure SHell) communication protocol is widespread or generalized, some network devices (switches, routers, firewalls) still need to connect to them in Telnet. This network protocol created in 1969 is insecure since the text exchanged circulates in clear on the network. Be careful because a sniffer type Wireshark or tcpdump can intercept communications exchanged between the host and his client. However, you can enable the Telnet Client of a Windows 10 computer to connect to a Telnet Server within your company.
