Dedicated instances of Meterian come with their dedicated client. The client is pre-configured to work against the dedicated instance and can be downloaded from the admin dashboard or using the standard public endpoint from the download area (/downloads/meterian-cli.jar), as in the following example.
Should you want to check whether your client is correctly connecting to the dedicated instance prior to launching a scan, execute the client with "--help", which will display the instance and the account it is connecting to.
The usage of the dedicated instance client doesn't differ from the public client. For further information on that please refer to the specific documentation section: Meterian Thin Client.
