See Wallarm's API Protection In Action
AI Runs on APIs.
AI Security Starts with API Security.
AI agents turn API calls into real actions across your systems. Wallarm secures the API layer, giving you real-time visibility and control over everything AI does.
The Shift
Why AI Security Starts at the API
AI security isn’t enough anymore. AI security protects models. But models act through APIs, and that's where the real risk lives.
Most AI security focuses on prompts, outputs, and model behavior. That’s necessary, but it’s not enough. AI agents interact with APIs, reuse credentials, and execute workflows across systems. The risk isn’t just what the model says. It’s what the agent is able to do.
Action-driven risk
AI security focuses on prompts and outputs. API security focuses on what AI agents actually do across systems, data, and real-world actions.
Connected system behavior
Agents don’t operate in one place. They move across services, reuse access, and trigger workflows that extend far beyond a single interaction.
Runtime visibility required
You can't understand agent behavior from logs alone. Securing AI requires real-time visibility into how actions unfold across APIs and infrastructure.

The Problem
APIs are the Control Layer of AI
AI systems rely on APIs to access data, integrate with applications, and execute actions across systems. That makes APIs the control layer of modern AI. Attackers are increasingly targeting APIs because they expose the most valuable parts of modern applications—data, logic, and automation.
If your APIs aren’t secure, your AI isn’t secure.
Shadow APIs
APIs created outside standard processes, without visibility, ownership, or security controls.
Hidden Endpoints
Undocumented APIs expose sensitive functionality that security teams don’t know to protect.
Logic Vulnerabilities
Business logic gaps attackers exploit through valid API calls that bypass traditional defenses.
Unintended Actions
APIs let AI agents take actions across systems that exceed intended scope or permissions.
API Sprawl
AI adoption accelerates API growth, expanding your attack surface faster than teams can track.

How the EU AI Act Makes API Security a Compliance Imperative
Your legal team just handed you a 400-page document and said "figure out compliance." The EU AI Act is live, your organization falls under its scope, which is broader than many expect.
