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.

Firewall Analyzer notifies the administrator instantly about the attacks through various means like Short Messaging Service (SMS), Email, and SNMP traps.

These reports ensure that the staff can analyze the threats and arrive at a contingency plan to tackle them if they recur in future.

He adds further how Firewall Analyzer helps him to manage the network, "Firewall Analyzer helps me to know the attacks that caused in my firewall and a drill analysis for each and every attack. It is a great product when it comes to notification. It helps our organization to know if there is any failed VPN transaction".
