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.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last year: -60.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
