Who is the CEO of NETSCOUT?

Co-founder Anil Singhal serves as chairman and CEO, a role he has held for the company's entire four-decade history.

Anil Singhal and Narendra Popat founded Frontier Software Development in 1984 in Westford, Massachusetts, building network performance tools for the then-emerging data communications industry. The company renamed itself NETSCOUT Systems in the early 1990s and went public on the Nasdaq in 1999 under ticker NTCT.

For two decades NETSCOUT grew steadily on the strength of its deep packet inspection technology, which could reconstruct exactly what happened on a network rather than sample it. The nGeniusONE platform became a standard in large enterprise and carrier operations centers.

The transformative moment was the 2015 acquisition of Danaher Corporation's communications business for $2.3 billion. That deal added Arbor Networks, the leading DDoS protection vendor, plus Tektronix Communications' carrier tools and parts of Fluke Networks' enterprise line, roughly doubling the company's size overnight.

Recent history has been less smooth. Revenue declined from a 2023 peak of $915 million to $823 million in fiscal 2025 as carrier spending softened and the company absorbed $427 million in goodwill impairment charges. Fiscal 2026 returned the company to growth at $859 million, alongside a planned leadership transition in the finance and operations ranks while founder Anil Singhal continues as chairman and CEO four decades on.

The 2015 transaction deserves deeper treatment because it remains the defining event of the modern company. Danaher spun off its communications test and service assurance business as NetScout, simultaneously merging it with the existing NetScout and adding Arbor Networks, Fluke Networks' enterprise line, and VSS Monitoring. Overnight the company tripled in scale and gained the DDoS protection franchise that now anchors its security revenue. Integrating four engineering organizations on different continents took most of the following half-decade.

NETSCOUT's Arbor line has been recognized repeatedly in analyst evaluations of DDoS mitigation, and the company holds positions in Gartner and IDC assessments of network performance monitoring and diagnostics. Its ATLAS threat intelligence is widely cited in industry DDoS reporting.

NETSCOUT recorded $427 million in non-cash goodwill impairment charges in fiscal 2025, reflecting reduced expectations for acquired businesses and drawing scrutiny of the 2015 Danaher deal's long-term value. The company has otherwise maintained a low public controversy profile, with periodic restructuring as carrier markets shifted.
