The CMS high-level trigger (HLT) makes use of the full event information to perform a fast reconstruction. Conventionally, the result is used to select events of interest and to store the full event data for later offline reconstruction. In an alternative approach referred to as Scouting, a highly compressed version of the reconstructed HLT event data is stored in a high-rate data stream. The seminar reviews how the Scouting data stream is defined, recorded, and analyzed to search for New Physics phenomena in a previously inaccessible phase space. Special focus lies on the Run 3 data-taking period, where improvements to the Scouting system enable new results, pushing the frontier of searches for New Physics and high-rate precision analysis.
