South Korean cybersecurity stocks surged across the board in early trading on the 14th. Nvidia CEO Jensen Huang’s identification of cybersecurity as AI’s next core application area fueled buying for a second consecutive day on expectations of industry growth.
According to the Korea Exchange, as of 9:14 a.m., SAND Lab was trading at 7,160 won (approximately $5.3), up 1,650 won (29.95%) from the previous session, hitting its daily price limit. At the same time, Fasoo AI jumped 27.15% to 4,800 won (approximately $3.6), Monitors Lab rose 23.49% to 3,575 won (approximately $2.7), and Hanssak gained 16.08% to 3,285 won (approximately $2.4).
S2W traded at 17,170 won (approximately $13), up 15.62%, while CyberOne rose 14.31% to 2,955 won (approximately $2.2). Dream Security and XGate posted gains in the 12% range, and RaonSecure climbed in the 10% range. Genians, Softcamp, and SGA Solutions showed strength in the 6% range, while ICTK advanced in the 4% range.
By 9:53 a.m., SAND Lab had retreated somewhat from its daily limit, trading at 6,750 won (approximately $5), up 22.50%. However, the broader rally held, with RaonSecure up 16.42% at 10,920 won (approximately $8.1), Dream Security up 11.45% at 2,920 won (approximately $2.2), and XGate up 6.97% at 17,180 won (approximately $13).
Huang’s Remarks and Market Reaction
The immediate catalyst for the surge was Huang’s comments at the Goldman Sachs technology conference held in San Francisco on the 10th (local time). He said at the event that “cybersecurity is likely to be AI’s next major use case.”
Huang explained that as AI models advance, computing programming automation is accelerating, which is simultaneously speeding up both attacks that exploit security vulnerabilities and the development of patches to block them. The outlook is that AI proliferation will create new security threats while also driving demand for AI-based security solutions to defend against them.
He projected that cybersecurity is highly likely to become AI’s next major application area, emphasizing that as programming automation accelerates, the pace of advancement in both offensive and defensive technologies is quickening.
Structural Shift in the Security Industry
Huang’s remarks are being interpreted as more than a simple stock tip—they offer structural insight into the relationship between AI and cybersecurity. The more AI automates code generation and software development, the faster both attackers and defenders can evolve their techniques.
This suggests the industry’s center of gravity could shift from static security solutions to AI-driven dynamic response systems. The possibility is raised that a model in which AI generates patches the moment vulnerabilities are discovered and learns attack patterns to respond preemptively could become the standard.
The market sees the benefits of this industry transformation extending beyond large established security firms to small and mid-sized specialists that are applying AI technology to security. That is the backdrop for the simultaneous surge in SAND Lab, which hit its daily limit, along with Fasoo AI and Monitors Lab.
Some, however, caution that profit-taking could emerge after the sharp short-term run-up. SAND Lab’s partial giveback of gains during the morning after hitting its daily limit is seen as reflecting such concerns.
