# Oracle Siebel Claims vs Evidence

This page compares marketing claims that Oracle Siebel makes on its own website with what real G2 users say in their reviews. Each claim's source link points to the page where it appeared. Claims are rated as follows: Supported when a clear majority of the reviewers who address it back it up, Disputed when a clear majority contradict it, and Mixed when reviewers are divided. Reviews that don't mention a claim are not counted.
