Decision brief

LLM Guard is a toolkit tailored for securing interactions with large language models, focusing on safeguarding against prompt injection and adversarial attacks.

Good fit when

  • - You need to secure your application from sophisticated prompt injection techniques.
  • - Your development process involves integrating LLMs into production environments where security is paramount.

Avoid when

  • - If you are working in a low-security environment or with small-scale projects where advanced security mechanisms are not necessary.
  • - In cases where integrating external libraries and ensuring Python version compatibility may introduce complexities that outweigh the benefits.
Requirements:
Min 2 GB RAM; Ensure you have Python version 3.9 or higher.; Some advanced features require additional libraries which are automatically installed as needed.
