Using Role Based Access Control (RBAC), you can configure access policies and manage users for your group—your organization.
Managing Pepperdata Services
You can stop and start the Pepperdata services or refresh the Pepperdata configuration settings anytime.

Obtain Pepperdata Downloads via cURL or Wget
The Pepperdata installation files and artifacts are available from the Downloads page. But you can also obtain the installation files and artifacts by using cURL or Wget commands—perhaps to save time and more easily manage many target machines. You must first generate an API key, and then include it in the cURL or Wget command’s
