Generative AI Security: OWASP LLM Top 10 for Builders

Security is not a launch blocker — it's a launch requirement

OWASP's LLM Top 10 gives shared vocabulary between security and ML teams. Here is how we apply it on client engagements.

Top risks we see in the wild

• Prompt injection: Untrusted content hijacking agent goals — mitigate with instruction hierarchy and tool sandboxing.
• Insecure output handling: Model text rendered as HTML or SQL — always treat output as untrusted input.
• Excessive agency: Agents with too many write tools — scope down and add approval gates.

Ship with defense in depth

Input sanitization, output encoding, secrets outside prompts, signed tool manifests, and continuous red-teaming in CI. Nanostack offers security reviews alongside AI builds — learn about our process.
