shinyapps.io security questions

Hi, we would like to start using shinyapps.io but before we do that we need to get clearance from our security engineers. Some of the questions that they have:

  1. How our data will be stored in the platform and what are the security configurations around the same
  2. Is the platform certified with any security certification like ISO, SOC2 Type2

Can anyone help, please?

Thank you in advance.
