note - I'm the project's maintainer

Have a look at the `--max-workers` and `--max-rate` arguments, which allow controlling the rate of API calls made against the cloud environment. You can use these to tweak executions against environments and ensure you don't hit API caps.

Note that this isn't a Scout Suite issue per se, but the consequence of how AWS implements rate limiting (i.e. it's account-wide, not per-principal). Any AWS tool will face the same limitations / hurdles.
