FIREWALL

A firewall acts as a security gateway between a protected customer network and the public Internet.
Challenge

Examples of threats to today's business networks include:
Unauthorized network or information access
As businesses increase internal network connectivity and collaboration with new customers and business partners, they need to effectively maintain control of their vital assets to preserve their competitive edge and limit corporate liability. New applications can increase business automation and collaboration, but can also open dangerous security holes, if not secured properly.

Decreased employee productivity and wasted bandwidth
Businesses need to effectively control the use of applications, such as peer-to-peer file sharing and instant messaging, which plague many unsuspecting businesses, to improve employee productivity and reduce the costs associated with Internet connectivity.

Unplanned network downtime
Businesses need highly reliable networks that help ensure continuous operations for maximum productivity, including support for planned and unplanned maintenance upgrades. These networks must be able to defend against threats such as Internet-based denial of service attacks or internal sabotage from disgruntled employees or
contractors.
