According to DeepLearning.AI, Meta has introduced LlamaFirewall, a comprehensive toolkit designed to defend large language model (LLM) agents against jailbreaking, goal hijacking, and vulnerabilities in generated code. This open-source solution is now available for free to any project with up to 700 million monthly active users, making robust AI security more accessible than ever. The toolkit targets critical challenges in LLM deployment by offering advanced detection and mitigation tools, which are essential for enterprise adoption and regulatory compliance. Meta’s move is expected to accelerate safe integration of AI agents in business applications and drive innovation in AI security solutions (source: DeepLearning.AI, Sep 16, 2025).
