The Cisco Policy Suite (CSP)

The Cisco Policy Suite is a complex software available for Mobile, WiFi and Broadband Network Gateways (BNG), which Cisco sells to Internet Service Providers (ISPs) and large corporate customers. Network administrators can set up bandwidth usage policies and subscription plans for customers/employees in the software.

The software is equipped with network intrusive functions that enable it to keep track of individual users and traffic on individual network layers. Access policies can also be enforced. Among other things, weak points were probably found in the product during internal audits.
