FAQPage Schema

How do I protect my LLM application from prompt injection attacks?▼

Protect LLM applications from prompt injection attacks by validating and sanitizing user-provided inputs at all trust boundaries to prevent malicious manipulation of AI behavior.

What is the best way to sanitize user inputs for AI agents?▼

The best way to sanitize inputs for AI agents is to enforce structured validation, implement allowlists, and separate instructions from data before processing external content.

How does prompt validation defend against malicious manipulation of AI behavior?▼

Prompt validation defends against malicious manipulation by checking inputs for potential malicious intent, mapping injection points, and rating risks to identify threats before processing.

Can I use input validation scripts with any AI system processing external data?▼

Yes, input validation scripts are applicable across diverse AI systems where user-provided content or external data is processed, ensuring structured validation of inputs and outputs.

How do I test prompt injection defenses against common attack payloads?▼

Test prompt injection defenses by verifying your security hardening measures against common injection payloads, logging agent actions, and setting up alerts for suspicious patterns.

Why do I need to separate instructions from data in LLM protection?▼

Separating instructions from data is a required defense strategy to prevent external content from overriding system prompts and manipulating AI tool calls or agent behavior.
