When the account is activated, you receive an e-mail with the URL information and access credentials for logging in to the CSO portal.
For on-premise CSO solution, you must have licenses to download and use the 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.
