 You want to deploy **[ggscout](https://docs.gitguardian.com/ggscout-docs/home)** in your Kubernetes cluster, but it doesn’t have access to the GitGuardian platform, preventing you from viewing the NHI inventory from the dashboard.
 
 `ggbridge` can help you establish a secure and mTLS-authenticated gateway between your network and the GitGuardian platform, allowing ggscout to communicate with the GitGuardian public API, and thus, transmit the inventory.
