A security control that sits between users and a large language model to inspect, filter, and modify both inputs (prompts) and outputs (responses) in real time. LLM firewalls detect prompt injection attempts, block requests for sensitive data, prevent jailbreak patterns, and redact personally identifiable information from model outputs. They function similarly to web application firewalls but are purpose-built for LLM traffic.
Organizations deploying customer-facing LLM applications need purpose-built defenses that traditional WAFs cannot provide. Security engineers configure and tune LLM firewalls as a core part of AI deployment. Understanding this technology is essential for anyone building or securing AI-powered products. The market for LLM security tooling is growing rapidly.
