Barracuda SecureEdge Access allows administrators to configure custom Access Agent networks with respect to each Private Point of Presence. The Barracuda SecureEdge Access Agent running on the client connects to the SecureEdge unified cloud UI. In addition, you can enforce agent web filtering policies to the web traffic that the clients connect to via the SecureEdge Access Agent in order to establish a secure connection to access internal and external company resources.
