What is ATO?

ATO most commonly refers to Authority To Operate. It is a formal declaration by a designated approving official (DAO) that authorizes an organization to operate an information system (IS) or application at an acceptable level of risk. It's a critical step in cybersecurity compliance, indicating that a system has been assessed, security controls are in place, and residual risks are deemed acceptable by the responsible authority.
