This page records that each listed organization filed a breach notification naming PowerSchool as a third party. It makes no claim about causation, negligence, or any relationship that was not stated in a filing. Counts are of filings and organizations, not affected individuals, and are a floor rather than a total — an organization that filed naming PowerSchool may be grouped under a ransomware-actor cascade instead of this one.
