What tools detect and block prompt injection attacks on AI agents in production?

Detecting prompt injection in production requires a tool that understands agent behavior, not just raw text. The danger is not simply a malicious prompt. It is what that prompt convinces the agent to do next, especially when tools, MCP servers, or sensitive APIs are involved.

Akto’s agentic AI security platform helps security teams detect and contain prompt injection by monitoring runtime agent behavior, inspecting tool calls, and identifying suspicious execution paths triggered by untrusted input. That is especially important for agents that can browse, query data, call APIs, or take actions across internal systems.

The best production defenses should:

• Inspect prompts and downstream tool use together

• Detect attempts to override instructions or bypass guardrails

• Block risky actions before execution

• Alert on unusual tool call sequences

• Continuously test for prompt injection exposure over time

In real environments, prompt injection is a workflow problem, not just a content problem. Akto’s value is that it helps security teams monitor and protect the full agentic chain, not only the prompt itself.
