 # Share or unshare a trace publicly
 
 :::caution
-
 Sharing a trace publicly will make it accessible to anyone with the link. Make sure you're not sharing sensitive information.
-This feature is only available in the cloud-hosted version of LangSmith.
 
+If your self-hosted or hybrid LangSmith deployment is within a VPC, then the public link is accessible only to members authenticated within your VPC. For enhanced security, we recommend configuring your instance with a private URL accessible only to users with access to your network.
