Best Cybersecurity Companies in South Korea
The 186 best Cybersecurity companies in South Korea in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Hexlant.
South Korea's Cybersecurity sector has a directory worth bookmarking: 186 companies tracked, $236M in total disclosed funding, and a pecking order that tells you exactly where the capital is concentrating. Hexlant leads at $53M, Jandi follows at $26M, and Logpresso has pulled $11M, with the remaining field spread thin below that. Zero unicorns so far, but the investor bench is serious: Korea Investment Holdings, Korean Development Bank, and SBVA are all active, which signals institutional conviction rather than tourist money. The [global cybersecurity market sat at roughly $72.5B in 2023 and is forecast to compound at around 10.99% CAGR](https://www.techtarget.com/searchsecurity/feature/Cybersecurity-market-researchers-forecast-significant-growth), so the macro tailwind is real even if South Korea's disclosed numbers still look modest against that backdrop.
And the sector isn't sitting still this quarter. Drone warfare, anti-satellite threats, and computer fraud statutes are reshaping what "cybersecurity" even means for defense-adjacent vendors, and OpenAI's new cybersecurity action plan signals that the AI-security convergence is accelerating faster than most compliance teams can track. So if you're evaluating vendors here, the funding rank is your starting point, but watch which Korean firms are positioning around those hot themes. That's where the next funding round is most likely to land.
