You can connect an unlimited number of IaaS cloud accounts to CloudSploit (AWS accounts, Azure subscriptions, GCP projects, or Oracle containers). Each account will be connected as an "unlicensed" account, meaning you can perform on-demand scans in the browser, but cannot take advantage of paid features such as continuous background scanning, saved reports, compliance reports, and more.
When you upgrade, you select the number of licenses you wish to purchase (e.g. "Standard Plan x10" gives you 10 licenses). From this license pool, you can apply a license to any of the unlimited number of accounts you connected. Those accounts can then take advantage of all of CloudSploit's paid features.
