KX NexG

KX NexG is a South Korean network security company founded in 2001 and based in Gangdong-gu, Seoul. Its business is secure connectivity — VPN gateways, firewalls, user authentication and the management systems that hold a distributed network of them together — sold largely to Korean enterprises and public bodies. Its products include the VForce UTM appliance line, SSL VPN for remote access, integrated wired and wireless security, a home network security solution, and an integrated security management system. It also offers a post-quantum VPN, using cryptography intended to remain secure against quantum computers, which is early for a vendor of this size and reflects Korean public-sector interest in the transition. Like other Korean appliance makers here, it is validated through domestic certification rather than the international malware laboratories, so the test columns in this index will generally be empty for it.
