Plantynet

Plantynet is a South Korean information technology company specializing in network security and content filtering. Founded on June 1, 2000, by Tae-joo Kim, an engineer with a background from LG Software and Delta Information & Communication, the company was the first in Korea to commercialize a network-based internet content filtering service. The firm went public on the KOSDAQ market on June 10, 2005.

The company's core business revolves around providing services that block access to harmful online content, such as obscene materials and gambling sites, and managing network traffic to improve efficiency. This is achieved through a proprietary database of harmful URLs, which is continuously updated using AI technology. Its primary clients are major Internet Service Providers (ISPs) and cable internet operators in South Korea. Plantynet has also expanded its services internationally, securing major telecommunication companies like Taiwan's Chunghwa Telecom and Vietnam's VNPT as clients. Its business model is diversified across three main segments: network services, which constitute about 50% of revenue; media content and services; and venture capital investments.

Through its subsidiaries, Plantynet has ventured into new business areas. Its subsidiary, PlantyM, operates a digital magazine platform called 'Moazine' and provides in-store music and digital signage services. Another key subsidiary, Albatross Investment, is a venture capital firm that invests in promising technology startups, contributing significantly to the parent company's profits through fund evaluation gains.
