Overview

A proxy server is a web server that acts as a gateway between a client application, for example, a browser, and the real server. It makes requests to the real server on behalf of the client or sometimes fulfills the claim itself.

Web proxy servers have two primary purposes, namely to filter requests and improve performances. Additionally, there are proxy servers that sit between web servers and web clients known as a reverse proxy. Reverse proxy servers pass on requests from web clients to web servers. They are used to cache images and pages to reduce the load on web servers significantly.

Glasswall CDR can be inserted into the transparent SSL inspection of traffic to disarm and rebuild dangerous files.

Instant threat removal for files moving between boundaries

• Leverage existing Proxy Server to remove threats from files which ingress or egress between trust boundaries without requiring user action or co-operation
• Apply CDR policies to web traffic that ensures your business and users are protected, while maintaining business continuity
• Industry standard implementation of Internet Content Adaptation Protocol (ICAP) to work with Proxy Servers to yield industrial strength protection for users

Use cases

• Cross Domain Solution where files are in transit across trust boundaries
• Safety net for users opening files from seemingly trustworthy URLs
• Inline security with either a forward or reverse proxy workflow
• Where file sandboxes or denotation chambers degrade user experience to become unworkable

How it works

Network appliances that support the Internet Content Adaptation Protocol (ICAP) provide an industry standard way to support transparent inspection of traffic by Glasswall CDR. Files are processed by Glasswall Halo with millisecond speed and returned free from threats so they can be safely opened and viewed by the user.
