Our evaluation of the two categories of PowerApps connectors (Business and Non-Business) have not been found to be adequate for organizations' requirements. What we are looking for is a mechanism where we can control which PowerApps connectors are available on the tenant via something similar to a Whitelist design method. For example: We would Whitelist five connectors to be available to licensed PowerApps users in our environment. No other connectors would be available. When a new connector is released from Microsoft, we would have the ability to whitelist that connector only when we have performed adequate testing (in our staging environment) and deemed it appropriate to use in our production environment. Due to the regulated nature of many of the business evaluating PowerApps, and the security principles they have in place, the above is the best way we see possible to sanction the use of PowerApps.
