NTCT

Netscout Systems, Inc.

A maker of network observability and cybersecurity tools, NetScout lets companies watch internet traffic in real time and defend against DDoS attacks; its nGeniusONE and Arbor products serve telecoms, governments, banks, and hospitals. Founded in 1984 as Frontier Software by Anil Singhal and Narendra Popat, the firm renamed itself NetScout to evoke "scouting" networks for trouble, and added its security arm by acquiring Arbor Networks. Fun fact: it built one of the first remote network monitoring probes in 1992.
