Soosan INT

Soosan INT makes software that lets South Korean home-broadband providers detect and manage routers that connect multiple devices to a single internet line, turning what was previously an unauthorised practice into a regulated, billable service.

Its customers are internet service providers, and it supplies this connection-management service exclusively to KT, SK Broadband, and LG Uplus, the three carriers that together cover the large majority of the country's high-speed broadband market. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company also provides corporate internet-security solutions built on the same traffic-filtering technology.
