Q

authorization to operate (ATO)

A

Often related to government or military agencies or contractors, an ATO is the formal approval to perform business functions once compliance with a contract, standard, framework, or regulation is confirmed. An ATO is often issued for a limited period of time and can be lost or canceled by the approving authority at any time based on any significant change to the environment.
