I used the JuiceSSH app (free version) in my mobile phone to connect remotely to the internal network devices in the enterprise environment. I also was able to use it while using a VPN connection outside of the network without issues. Review collected by and hosted on G2.com.
Something I really like about the application is the ability to configure multiple credentials to be used and the ability to add multiple devices so you can manage them directly from your mobile. Also, it is ads-free. Review collected by and hosted on G2.com.
