Rigol is pretty famous for not really caring a single bit about security. It's helpful in one particular area, in that they sell the device in the OP for anywhere between $900 and $2900 depending on which features are enabled, except all of those features are software locked with the same attention to security as they do everything else. The result is that you can get a hell of a lot of scope for very little money, but don't expect it to offer things like "robust security".
