For the cloud-hosted CSO solution, you need to purchase licenses to manage devices in CSO. As part of the activation process, you must provide the information required for creating your CSO account. After the account is activated, you receive an e-mail with the URL information and access credentials for logging in to the CSO portal.
For the on-premises CSO solution, you must have licenses to download and use Juniper Networks CSO. When you order licenses, you receive the information that you need to download and use CSO. If you did not order the licenses, contact your account team or Juniper Networks Customer Care for assistance.
