Organizations Adopt LLM Firewalls To Secure Systems

Security teams and product builders are adopting LLM firewalls to inspect prompts, retrieval pipelines, model outputs, and tool calls. The article outlines input, retrieval, output, and tool controls—including prompt-injection detection, PII redaction, retrieval scanning, and scoped tool permissions—to reduce data leakage and unsafe actions. It recommends centralized gateways, DLP for prompts/responses, logging, and least-privilege credentials for production GenAI features.
