Value-added resellers, distributors, and system integrators help sell and fulfill international deals.
Strategy
NETSCOUT is extending its platform beyond traditional service assurance into adjacent cybersecurity and analytics use cases, especially enterprise security and NDR. Management is also focused on expanding internationally, broadening deployment flexibility, and controlling costs while continuing to invest in product development and customer expansion.
Broadens the addressable market and increases wallet share from existing network telemetry.
The installed base creates cross-sell opportunities and lowers customer acquisition cost.
International markets are a large part of revenue and depend on partner coverage.
Supports more customer environments and improves competitiveness versus point solutions.
Geography
2026The company is headquartered in the United States, but a large share of revenue comes from international markets through channel partners and direct sales. In the nine months ended December 31, 2025, the United States represented 57% of revenue and international markets 43%, with Europe, Asia, and the rest of the world contributing meaningfully to the mix.
Share of the revenue the company reports by geography.
Risks

The company also relies on channel partners for a large portion of non-U.S. sales, and its products face operational, cyber, and AI-related risks because they are used in critical network environments.
