avast! 4 ISA Server Edition

Antivirus solution for your MS ISA Servers (also works with MS Proxy Server 2.0). Provides real-time scanning of HTTP and FTP traffic at the gateway, greatly reducing the risk of infection from the World Wide Web (including web-based mails etc.).

avast! ISA Server Edition provides effective protection for Microsoft ISA 2000 Servers (and also works with MS Proxy Server 2.x). Its main features include high-performance scanning, superior scalability and strong reporting capabilities. It perfectly integrates with ISA Servers via Microsoft's own "ISAPI" interface.

The product works as a plug-in for avast! Server Edition. Therefore, it uses the same high-performance, award-winning, ICSA-certified engine as the Server Edition itself, providing you with maximal protection.

Real-time HTTP Scanning

avast! ISA Server Edition's most important job is the real-time scanning of all HTTP traffic. With today's boom of free webmails and other online hazardous content, HTTP scanning is becoming a real necessity. Thanks to a tight integration with the ISA Server itself, avast! is able to detect and remove viruses from all WWW pages/downloads. It does not matter how a client is downloading the infected program - be it using IE or any other browser, any 3rd party download acceleration tool or any other way - you can be confident that it will be properly screened and disinfected before it reaches the user. Of course, the scanning is not confined to programs - scripts, ActiveX objects and any other potentially hostile objects are monitored as well.

Special care has been taken to correctly handle even huge downloads (a typical problem of gateway-based AV solutions). avast! makes sure that scanning is performed properly even for these objects, still making sure that the client programs will not time-out waiting for a response from the proxy.

Real-time FTP Scanning

Besides real-time HTTP scanning, avast! is able to filter FTP traffic as well.

FTP is still an important protocol for file transfers (i.e. downloads as well) and as such deserves almost as much attention as HTTP scanning. Thanks to the design of the CERN Proxy protocol (also known as the HTTP proxy protocol), avast! is able to transparently handle all FTP traffic using its HTTP filtering module.

High scalability

avast! ISA Server Edition is easily deployable and works perfectly even on large datacenter servers and cluster servers. The scanning engine was designed with two basic goals in mind: performance and stability. It's able to take advantage of multiple CPUs, fully leveraging the potential of today's advanced server hardware. Also, it supports scanning in memory (including the decompression of archives / packed files), resulting in unrivaled scanning speed and robustness.

URL Blocking

avast!, ISA Server Edition also contains a simple URL blocker. You can specify URL masks (such as http://www.penthouse.com/* or *xxx*) of addresses that will be blocked from all access. This is a very simple yet extremely powerful way to prevent certain sites from being visited from the workspace.

Alerting & logging

As with any server-side software, it is very important to provide effective means of monitoring. For these purposes, avast! offers a wide range of possibilities. These include thorough notification capabilities via e-mail and avast's built-in Notification Manager (that supports a number of other transport protocols), rich logging features, and performance counters.

Automatic updates

The ISA Server Edition uses identical updating modules as avast! Server Edition itself, resulting in unparalleled speed and size of updates. The updates can be either installed automatically by the updater, or manually. It is also possible to set the system up so that the updater first asks the administrator - prior to installing any updates.
