Client and server model

Endpoint security systems operate on a client-server model, with the security program controlled by a centrally managed host server pinned with a client program that is installed on all the network drives. There is another model called software as a service (SaaS), where the security programs and the host server are maintained remotely by the merchant. In the payment card industry, the contribution from both the delivery models is that the server program verifies and authenticates the user login credentials and performs a device scan to check if it complies with designated corporate security standards prior to permitting network access.
