  • Certificates are used to authenticate products distributed under your license and identify computers on your network to help ensure secure communication between your ERA Server and clients


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 ERA Server during the remote installation of ESET products.

In some cases, you might want to create a new certificate to set specific parameters for a certain group of client computers, for example, create a limited-duration certificate for a group of computers that will only be in use for a limited time.
