Why it matters
Prompt injection remains a fundamental risk for any AI feature accepting untrusted input, but this page is an evergreen glossary definition paired with vendor marketing rather than a new finding or actionable disclosure.
A glossary entry from Behest AI defines prompt injection — the class of attack where crafted user input or content a model reads smuggles instructions into an LLM to override its system prompt, leak a hidden prompt, or exfiltrate data. The page also markets Behest's Sentinel defense, which matches requests against detection patterns and blocklists in shadow or enforce modes before requests reach the LLM.
