What does Lakera Guard do?

Lakera Guard is a security platform specifically designed to protect AI applications built on large language models (LLMs). It acts as a protective layer that scans and analyzes all inputs and outputs to your AI systems, detecting and blocking malicious prompts before they reach your model. The system works by analyzing prompts in real-time (with sub-50ms latency) across 100+ languages, identifying potential threats like prompt injection attacks, data leakage attempts, and jailbreaks that could compromise your AI's behavior or expose sensitive information.

What sets Lakera apart is its context-aware detection system that learns from real-world attacks. The platform continuously evolves its protection based on data from over 1 million security researchers who participate in their Gandalf hacking challenges. This means the system gets smarter as new attack methods emerge, without requiring manual updates. It's model-agnostic, working with any LLM, and offers centralized policy control that lets security teams customize protection rules without disrupting development workflows.

This tool is essential for enterprises and development teams building AI-powered applications, particularly in regulated industries like finance, healthcare, and technology. Use cases include securing customer service chatbots to prevent data leaks, protecting internal AI tools from prompt injection attacks, and ensuring compliance when deploying AI in sensitive environments. It's particularly valuable for companies that need to maintain user trust while accelerating their AI adoption safely.
