Exceptions OU
The Exceptions OU houses accounts that require an exception to the security policies that are applied to your Workloads OU. Normally, there should be a minimal number of accounts, if any, in this OU.
Service control policies and scrutiny
Given the unique nature of the exceptions, SCPs are typically applied at the account level in this OU. Due to the customized security controls that apply to these accounts, owners of these accounts can expect to experience greater scrutiny from security monitoring systems.
Consider Workloads OU as an alternative
If you observe a pattern in which multiple accounts require the same set of exceptions, we recommend that you examine either your existing workloads policies or an extended form of the Workloads OU structure and house the accounts under the Workloads OU. You can introduce another level of OU under the Workloads OU to represent a common set of security policies and/or operational processes that can be applied to multiple workload environments.
