1. A method comprising: capturing data streams from multiple carriers on common data lines on a Wide Area Network (WAN) to be stored within a multi-tenant capable Network Monitoring System (NMS) configured to monitor a set of activities between users of the WAN; receiving, at the NMS, an identification of a first analyst authorized to receive data related to a known user of interest thereto, the known user of interest being a user of the WAN whose activity is monitored through the NMS; receiving, at the NMS, an identification of a second analyst also authorized to receive data related to the known user of interest; receiving, at the NMS, a known user ID associated with the known user of interest configured to be monitored at an access device communicatively coupled to the WAN from the first analyst and the second analyst; parsing, at the NMS, a data stream of the captured data streams related to the known user of interest into a common portion relevant to both the first analyst and the second analyst, a first unique portion solely relevant to the first analyst and a second unique portion solely relevant to the second analyst following the reception of the identification of the first analyst and the identification of the second analyst and the reception of the known user ID from the first analyst and the second analyst; parsing, at the NMS, a single instance of the common portion of the data stream to simultaneously retrieve the common portion for both the first analyst and the second analyst; retrieving, through the NMS, a first data stream related to the known user of interest based on the reception of the known user ID from the first analyst and the identification of the first analyst, the retrieving of the first data stream comprising retrieving both the first unique portion and the common portion; retrieving, through the NMS, a second data stream related to the known user of interest based on the reception of the known user ID from the second analyst and the identification of the second analyst, the retrieving of the second data stream comprising retrieving both the second unique portion and the common portion; transmitting the retrieved first data stream related to the known user of interest solely to the first analyst; transmitting the retrieved second data stream related to the known user of interest solely to the second analyst; and modularizing the NMS such that the first analyst and the second analyst are provided with a capability to scale a functionality providing the data stream related to the known user of interest as per a requirement thereof.
