6 cybersecurity & identity providers in South Korea, publishing 31 APIs.
6 providers
31 published APIs
102 indexed documents
Cybersecurity & Identity in South Korea — 6 providers on the APIs.io network sit in both cohorts, and between them they publish 31 indexed APIs.
All 6 publish at least one machine-readable API — unusual, and worth noting against most cells in this grid.
By Kin Score band: 2 thin, 2 emerging, 1 strong, and 1 developing.
Leading by rating: PortOne, SK Telecom, Kakao, Hanyang University, Toss, and Naver.
Country membership is exact-tag only. A provider lands in South Korea when one of its own top-level tags names the country — there is no headquarters signal on the country axis, unlike the region axis which reads tag, provider-name pattern, and stated HQ. So this cell is a floor, not a census, and it understates by construction — a cybersecurity & identity company headquartered in South Korea that never tags itself is counted nowhere on this axis. The region cuts read the wider signal set and will generally hold more.

All of Cybersecurity & Identity →
This page is the intersection of two independently computed cohorts:
South Korea and
Cybersecurity & Identity. A provider appears here only when it is
already a member of both. South Korea membership is matched on tag,
so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
Work with this as data
Every country here is available over the APIs.io API and to AI agents over MCP. Countries is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
