. By 2028, the market is forecast to nearly double again, reaching $7.7 billion. This rapid expansion reflects the urgent pressure on enterprises to secure their AI initiatives as they confront a new generation of cyber threats specifically targeting artificial intelligence systems.

"This surge is driven by the urgent need for enterprises to secure AI systems, address emerging vulnerabilities and strengthen defenses against sophisticated cyberthreats," said Shailendra Upadhyay, Senior Principal Analyst at Gartner1

. The growing adoption of AI is creating fresh vulnerabilities for businesses, including risks linked to AI models, third-party software, open-source components, and supply-chain attacks that conventional security infrastructure struggles to address.

Critical Vulnerabilities Driving Enterprise Investments

Gartner predicts that over half of successful cyberattacks targeting AI agents by 2029 will exploit access control weaknesses and prompt injections1

. These AI-specific attack vectors represent a fundamental shift in the threat landscape, pushing companies to deploy specialized AI security tools alongside their existing cybersecurity infrastructure. Without adequate security and visibility controls, enterprise investments in AI initiatives face a high risk of failure.

Traditional security tools often treat AI applications like any other software and require significant updates to address AI-specific threats, according to Upadhyay1

. The deployment of autonomous AI systems introduces vulnerabilities that conventional security monitoring may not detect, creating an urgent need for organizations to identify, monitor, and protect AI models from unique threats that didn't exist in traditional software environments.

Four Market Segments Leading the Charge

The AI security market divides into four main segments: AI application security, AI usage control, AI governance platforms, and AI gateways1

. AI application security is expected to remain the largest spending category in 2027, reaching nearly $851 million, followed by AI usage control at $749 million. However, AI usage control is forecast to be the fastest-growing segment, expanding 73%, while spending on AI gateways is expected to grow 70.9%.

These specialized solutions address challenges that traditional security systems cannot handle effectively. As defenses like AI runtime protection and dedicated gateways become more reliable, organizations will gain confidence in these tools, accelerating adoption across enterprises. The need for specialized AI security tools will intensify as businesses expand their AI initiatives and face vulnerabilities in AI models that extend beyond the reach of traditional monitoring systems.

Intensifying Competition and Market Consolidation Ahead

Competition in the AI security market varies significantly by segment. For AI governance platforms and AI gateways, which often build on existing enterprise systems for governance, data, and API management, established vendors are likely to maintain their lead by adding AI capabilities to existing products1

. Meanwhile, AI application security and AI usage control segments are attracting a growing wave of startups entering the field with innovative approaches.

The rapid expansion of the market could trigger significant consolidation, with larger cybersecurity companies likely to acquire startups to expand their AI security offerings, Gartner noted1
