Firewall for AI
Protection for applications using LLMs
Firewall for AI protects applications using Large Language Models against specific attacks such as prompt injection, jailbreaking, data extraction, and PII leakage. The system analyzes both user input (prompts) and model output (responses) in real time, blocking malicious patterns before they reach the model or the user. Per-user and per-model rate limiting protects against abuse of costly APIs. Sensitive data detector blocks leaks of PII, credentials, and intellectual property in AI responses.
