• Create and deploy a new certificate for new workstations to automatically join a Dynamic Group based on Certificate serial number

To create a new certificate or Certification Authority, or to create a new certificate set to other specific parameters for a certain group of client computers, see the following Knowledgebase article: 

• Create a new certificate or certification authority in ESET Security Management Center (7.x)

Certificates are used to authenticate products distributed under your license to identify computers on your network, which ensures a secure communication between your ESMC Server and clients, and also to establish secured connection of ESMC Web Console. 

Your Certification 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 ESMC Server to allow for remote installation of ESET products.

To create a new certificate in ESET Security Management Center for new workstations to automatically join a Dynamic Group, follow the instructions below:

1. Open ESET Security Management Center Web Console (ESMC Web Console) in your web browser and log in. How do I open ESMC Web Console?

2. Click More → Peer Certificates → New → Certificate.

   1. Description: Type in a descriptive name to identify which computer or which Dynamic Groups this certificate will be for.
