Telecommunications

A telecom equipment manufacturer contracted us to identify their worldwide presence on the Internet. We then proceeded to the vulnerability analysis of their network in more than 40 countries.

A market leader in wireless communications asked us to design and implement specific GPRS security controls. We also developed several middleware applications for their Value-Added Services systems.

We conducted the entire security architecture design of a large GSM network. This started with an external penetation test that uncovered serious vulnerabilities and resulted in a complete new blueprint for a solution comprising IDS, central log, efficient firewalling, secure remote acess system and a new high-available IP network layout.

A fast growing GSM operator asked for our help with its internal fraud problem. Our mission led to the discovery of several fraud cases and allowed the operator to significantly reduce its losses.

A market leader in financial trading systems asked us to perform risk analysis on several of their mission-critical projects. This included the complete security review of their Index Calculation System used to provide securities quotes to stock markets worldwide.
