To create a new certificate or certificate authority, or to create a new certificate set to other specific parameters for a certain group of client computers, see the following Knowledgebase article:
Certificates are used to authenticate products distributed under your license to identify computers on your network, which ensures a secure communication between your ERA Server and clients, and also to establish secured connection of ERA Web Console.
Your Certificate Authority (CA) is used to legitimize certificates distributed from your network. In an enterprise setting, a public key can be used to automatically associate client software with the ERA Server to allow for remote installation of ESET products.
To create a new certificate in ESET Remote Administrator for new workstations to automatically join a Dynamic Group, follow the instructions below:
Open ESET Remote Administrator Web Console (ERA Web Console) in your web browser and log in.
The new Dynamic Group is now ready to filter new workstations based on the certificate serial number. When you create an Agent installer, select the new certificate and it will be added to the new Dynamic Group.
