Overview
Severity: MEDIUM | Affected: OWASP | Category: tool
The Open Web Application Security Project (OWASP) has announced the official release of 'Guardian,' a new open-source AI firewall designed specifically for Large Language Model applications. Guardian acts as a proxy between users and LLMs, actively inspecting prompts and responses in real-time. It uses a combination of semantic analysis, anomaly detection, and configurable rule-based filters to block a wide range of attacks, including complex prompt injections, data exfiltration attempts, and jailbreaking techniques. The tool is designed to be highly extensible, allowing developers to add custom detection modules for specific threats or application contexts. The release aims to provide a standardized, community-driven security layer for developers building with LLMs, addressing a critical gap in the AI application security stack.
