At Custodet Nimbus, we take the security of your data seriously.
The credential sets you enter into your phone or tablet stay there - on your device, safely stored in the device's encrypted secure storage. We've taken great pains to make sure that we have no visibility into information that you should consider secure and private.
That said, when you install and configure our software to connect to your environment, we still strongly recommend and encourage you to use IAM accounts specifically set up for this platform. These accounts should be created with the minimum permissions allowing them read access to CloudWatch resources in your environment. Doing so will make us both sleep better at night. Should you need them, directions for this will be available here soon.
