Internet Security and Acceleration Server 2000 is a Microsoft product that is used to provide powerful security and network acceleration while accessing the Internet. It works as a firewall as well as a Web cache server. It integrates with the Microsoft Windows 2000 operating system for policy-based security, acceleration, and management of internetworking.

Why?

With the expansion of Internet, security and performance challenges have increased manifold. The interconnection of networks has now become a major security threat for organizations. Nowadays, organizations require the control of information flowing to and from the Internet. Bandwidth consumption is also a prime consideration for the organizations, as it affects the performance of a network.

Microsoft ISA Server's firewall and Web cache functions provide a common management infrastructure that reduces network complexity and costs. Administrators can opt to deploy it as an integrated system or as a separate firewall and cache. Its firewall services secure the internal network against attacks from the Internet. Its Web cache services help in reducing bandwidth consumption, which enhances network performance.

Flexible management tools, provided by ISA Server, offer multi-level policies for users, applications, destinations, schedules, and content types.
