Traditional cybersecurity has been built on three pillars: endpoint, network, and cloud security. As AI agents become embedded in enterprise operations, a fourth pillar is emerging: AI security. Because autonomous AI systems interact with enterprise tools and data almost exclusively through APIs, API security sits at the core of this new domain. Existing security pillars fall short because they weren't designed for machine-speed, API-driven architectures. AI security also encompasses model security, LLM-specific risks like prompt injection, agent governance, and compliance frameworks. The argument is that just as each prior computing shift spawned a new security discipline, the rise of AI-first architectures is triggering the next evolution in cybersecurity strategy.
