Metadata

You can add arbitrary metadata to your guard screening requests to enable more detailed analysis of requests in the Lakera Guard platform or external tools, as well as for cross referencing.

Metadata use cases

Metadata can be specified for an individual screening request or via the associated Project. This provides flexibility to combine session-specific metadata with more general application metadata for each request.

The context that this metadata provides in the Guard platform can help identify suspicious activity patterns and users or even identify specific attacks as they are happening.

You can also export logs from Guard to your Security Information and Event Management (SIEM) system or another tool of your choice for further analysis.

Project metadata tags

Common use cases for Project metadata include:

• Application ID: Specify the application the project relates to. This can help identify suspicious activity in specific applications in your ecosystem or allow you to compare performance between different applications.
• Model: Specify the underlying LLM, e.g. GPT-3.5 Turbo.
• Environment: Specify the environment the project relates to. This can help identify suspicious activity in specific environments or allow you to compare performance between e.g. production and testing environments.

You can create your own custom metadata tags. For more details on how to set up project metadata tags, please see the Projects documentation.

Screening request metadata

Common use cases for screening request metadata include:

• User ID: Specify the user ID of the end user interacting with the LLM.
• Session ID: Specify the session ID of the end user LLM interaction.

Request metadata can help identify suspicious users or patterns of behavior.

You can pass your own arbitrary request metadata tags in screening requests, they do not need to be configured.

Attaching metadata to requests

Metadata can be attached to requests using the metadata property in the guard request body. The metadata property is an object that can contain any arbitrary key-value pairs.
