Overview

As a leading financial services firm advising an international clientele, Greenhill is keenly attuned to compliance issues. To meet strict federal requirements for capturing the content of all interaction with customers, it must monitor and control all forms of communications. In its efforts to comply, Greenhill was experiencing numerous issues with its incumbent firewall from Juniper Networks. In particular, monitoring and controlling webmail was problematic. Webmail applications were easily evading detection by legacy “port-blocking” firewalls and other security infrastructure by tunneling over SSL. Greenhill needed a flexible solution that would afford it network visibility, even into activities tunneled over SSL, and then allow it to select which users to block, assign different blocking criteria for certain users, and set such policies based on an Active Directory (AD) group.
