Security and service challenges at Tigo

Tigo, is a worldwide mobile phone service provider. The company has to assure trouble free service at all times. The up time of the network should be 100%. A vulnerable network will dent the telephone service performance. Hence, a stable and secure network is must for such service providers.

The stability and security can be achieved by continuous monitoring of network. The network needs to be monitored more precisely for attempts of external attacks at the Firewall. Another critical area is monitoring their cash cow VPN services. This is of greater importance because the corporate/government clients rely on it. So, with primitive tools Tigo was finding it very difficult to secure the network and provide uninterrupted VPN service.
