Computer-implemented systems and methods are disclosed for indexing and aggregating proxy server data. In accordance with some embodiments, the systems comprise a memory device configured to store a set of instructions, and one or more processors configured to execute the set of instructions to receive a plurality of log lines of proxy server data comprising a plurality of data components and index one or more of the plurality of data components for the plurality of log lines. The processors also generate a plurality of log data records, each including the one or more indexed data components, and generate a summarized data record by aggregating one or more log data records having at least one matching indexed data component.
