It is a challenge to access and manage embedded devices remotely. Very often we see that devices rely on being able to be reached on port 22 for ssh remote shell login. More advanced setups route all traffic through a VPN but then this VPN needs to be deployed and managed as well.
qbee.io has an integrated and secure VPN solution already setup and configured. Together with its remote shell access through the web application or its qbee-connect desktop tool all ports are securely accessible for ssh or even web server pages like node-red or similar GUIs.
Therefore our clear recommendation is to use the configuration engine of qbee.io to define that all traffic from the outside should be dropped. No more visible port 22 and one attack vector less for your system.
