Prompt injection is when someone inserts harmful or misleading text into an AI’s input to manipulate how it responds. This can cause the AI to produce incorrect, biased, or even dangerous outputs, or reveal information it shouldn’t. Because prompt injection can make AI behave in unexpected or harmful ways, protecting against it is key to keeping AI systems safe and trustworthy.

Why it matters: Prompt injection can cause AI to produce harmful or unauthorized outputs, making it a critical threat to trust, security, and brand safety.
