Ghost student fraud is a networked problem — fraud rings operate across multiple campuses, which means patterns that are invisible at any single institution become visible at the network level. The Clearinghouse covers 97% of currently enrolled postsecondary students across more than 130 million enrollment records, making it the only organization positioned to identify coordinated activity across the higher education system at this scale. Where most tools can only see within a single application at a single institution, Sentinel 360 can link cross-institutional enrollment signals and surface anomalies that siloed systems simply cannot detect.
