AI Agents
The Landscape. The Architecture. The Adoption. The Risk.
Market Landscape
The AI agent market is projected to grow from $5.1 billion in 2024 to over $47 billion by 2030, a compound annual growth rate of roughly 45%. Gartner projects 40% of enterprise applications will embed task-specific AI agents by 2026, up from less than 5% in 2025.

ARCHITECTURE PATTERNS
Production agent architectures have stabilized around a few proven patterns after years of experimentation. The dominant approach is pattern composition: Plan-and-Execute at the orchestration level, ReAct within each discrete step, and hierarchical multi-agent delegation for complex domains that require specialist judgment. No single pattern wins outright - the systems shipping in 2026 layer all three.

ENTERPRISE ADOPTION
Enterprise AI agent adoption accelerated through 2024 and 2025. McKinsey found 72% of organizations adopted AI in at least one business function, with generative AI usage doubling in under a year. The pilot-to-production gap is closing but remains significant: procurement cycles, security review, and change management slow deployment even when the technology is proven. The organizations that moved early are widening their lead.

SECURITY AND GOVERNANCE
The most urgent finding in this report is the governance gap. As AI agents proliferate, security teams are losing visibility. The Saviynt/Cybersecurity Insiders survey of 235 CISOs found 92% lack full visibility into AI identities operating in their environment, and 97% expect a material AI-agent-driven security incident within 12 months.
