[WPMU DEV Dashboard] WPMU Dashbord security issues

Hi, we have a bank client who has to have specially secured hosting. We want to use Hummingbird and Smush Pro on their site but their server admin is concerned about security of giving the WPMU Dashbord to the site. Is there something special that you tell bank clients to do to configure WPMU Dashbord securely? Please let me know if I need to ask the server admin any specific questions to make sure eveything is secure.
