# PromptArmor

> Integrating with PromptArmor

## PromptArmor

[PromptArmor](https://promptarmor.com/) is a service which checks LLM inputs for adversarial content *before* a completion is made. PromptArmor returns in realtime faster than LLMs, blocks 99% of known threat vectors, and takes less than 15 minutes to integrate.

PromptArmor integration is included in Baserun's Python SDK as an Automatic Evaluation.

To use PromptArmor, first set the `PROMPTARMOR_API_KEY` environment variable to your PromptArmor API key. Similar to other automatic evaluation features, you can then use the `baserun.evals.check_injection()` to evaluate a prompt using PromptArmor.

For more details on how our evaluations work, see the [Automatic Evaluation](/evaluation/automatic-evaluation) documentation for more details.
