Blue Coat ProxySG 8100 Series

Blue Coat ProxySG 8100 Series

The Blue Coat ProxySG 8100 Series offers a high-end proxy appliance platform that enables even the largest enterprises to accelerate and protect applications across the distributed network. Located at the Internet gateway, the ProxySG 8100 platform prevents malware and unauthorized applications from compromising network security or performance.

As the core of an organization’s application delivery network infrastructure, the ProxySG 8100 provides controlled acceleration of business applications across the globally-distributed enterprise. Leveraging Blue Coat’s acceleration technology, the ProxySG 8100 enables branch office users to enjoy the same LAN-like performance and experience as those located at headquarters or the data center.

Deployed at the data center, the ProxySG 8100 accelerates web applications and content from origin Web servers, while securely isolating them from direct Internet access. Optional SSL services secure communications and off-load application servers from computationally-intensive processes.

Centralized policy administration is provided by Blue Coat Director, while Blue Coat Reporter provides log aggregation from multiple ProxySG appliances into concise reports to analyze web communications and policy enforcement.

Accelerate — Enterprise applications

The ProxySG 8100 appliances form the core of an enterprise’s application delivery infrastructure. The ProxySG appliances feature MACH5 technologies allowing enterprises to deploy applications enterprise wide and providing users at remote locations same user experience over WAN links as the local users enjoy at the head quarters over a LAN.

Blue Coat’s application acceleration solution, featuring MACH5 (Multi-protocol Accelerated Caching Hierarchy) technology, enables organizations to accelerate delivery of all key productivity applications to users in branch and remote offices. Key acceleration technologies that build up MACH5 are

  • Bandwidth Management
  • Protocol Optimization
  • Object Caching
  • Byte Caching
  • Compression

Key applications accelerated using MACH5 are –

  • File services
  • Email/Exchange
  • Web applications
  • Video and Audio (Rich media applications)
  • Secure Web (encrypted SSL) applications

In addition, ProxySG 8100 appliances can accelerate web applications by offloading CPU intensive tasks from web servers and thus enabling web servers to run application logic faster.
