Hi,
If your vendors are using BOX, they should have a contractual relationship with BOX. Therefore, BOX would be a 3rd party from your vendors' perspectives, and they are responsible for ensuring that BOX has the requisite security and privacy controls. If your vendors are obligated to provide you their SOC 2 reports, these reports should include narratives as to their vendor oversight programs; if the SOC 2 reports do not identify BOX as their 3rd party vendor, I suggest that a follow-up is necessary to ensure that BOX is included.
The BOX web site includes a "Trust Center" that has information on how BOX achieves compliance and security. This section of the web also has BOX's SOC3 report, which is public.
