The AI security market is expected to enter a steep growth trajectory over the next two years. The expansion of autonomous AI and resulting emergence of new vulnerabilities, coupled with increasing demand for specialized security solutions, are identified as key drivers of market growth.

Shailendra Upadhyay, Senior Analyst at Gartner, stated, "As supply chain attacks leveraging third-party and open source software utilized in AI projects increase, enterprises face heightened risk of AI initiative failure without appropriate security control measures."

The AI security market comprises four segments: △AI application security, △AI usage control, △AI governance platforms, and △AI gateways.

As of 2027, AI application security is projected to be the largest segment by spending size, reaching approximately $851 million (approximately 1.2 trillion won).

In terms of growth rate, AI usage control leads at 73%, followed by AI gateways (70.9%) and AI governance platforms (68.0%).

Gartner forecasts that through 2029, attacks exploiting access control vulnerabilities and prompt injection will account for more than half of successful cyber attacks targeting AI agents.

Competitive dynamics vary by segment.

AI governance platforms and AI gateways are frequently built upon existing governance, data, and API management systems, indicating that established major vendors are likely to maintain market leadership through adding AI capabilities or integrating specialized products.

Conversely, AI application security and AI usage control segments are witnessing active startup entry.

Analyst Upadhyay forecasted, "As the market grows, major cybersecurity enterprises will actively pursue startup acquisitions and mergers to expand their portfolios," adding that "competition for market share among vendors will intensify further."
