Establishing and maintaining control over Web-based communications is more complex - and critical - than ever before. Organisations increasingly depend on the Internet for business critical content, applications and transactions. However, today's demands for Web- based information and instant messaging contribute to security risks, lower productivity and intellectual property loss.

Blue Coat ProxySG appliances integrate advanced proxy functionality with security services such as content filtering, IM control and Web virus scanning -without impacting network performance. Delivered as a rack mountable appliance for simple installation and management, the Proxy SG easily integrates with existing security and network infrastructure to provide comprehensive visibility and control of Web users, content and applications.
