Applications

Applications performs DPI Deep Packet Inspection. DPI is an advanced method of network packet filtering that is used for inspecting data packets exchanged between the devices and systems over a network. DPI functions at the Application layer of the Open Systems Interconnection (OSI) reference model and enables users to identify, categorize, track, reroute, or stop packets passing through a network. of local traffic and detects over 1500 applications on the network. Applications allows you to configure both application and application category policies within a given user role.
