System and method for aggregating data from a plurality of data sources

A computerized method, performed by a computing system having one or more hardware computer processors and one or more non-transitory computer readable storage device storing software instructions executable by the computing system to perform the computerized method comprising:

• accessing, from a first data source, first data items each associated with one of a plurality of individuals, the first data items indicating one or more of a badge-in time indicating entrance to a physical facility or a badge-out time indicating exit from the physical facility;
• generating, for each individual, a first summary of first data items associated with the individual;
• accessing, from a second data source, second data items each associated with one of the plurality of individuals, the second data items indicating one or more of system login time, system logout time, VPN login time, or VPN logout time;
• generating, for each individual, a second summary of second data items associated with the individual, wherein at least the first summary and the second summary are each accessible by the computer system;
• determining, a first group of unique individuals each sharing a first correlation between the first summary and the second summary;
• determining a second group of unique individuals each sharing a second correlation between the first summary and the second summary;
• generating a first output based at least on first data items and second data items of individuals in the first group;
• generating a second output based at least on first data items and second data items of individuals in the second group;
• determining a first security indicator for the first group relative to the second group based at least in part on comparison of the first output and the second output;
• and
• generating user interface data configured to cause display of a user interface on a user computing device, the user interface including an indication of the first group, the second group, and the determined first security indicator.
