Features

Nsauditor (Network Security Auditor) is a Windows-based multi-purpose tool designed to scan networks and hosts for vulnerabilities, and to provide security alerts.

StorageSafe is another offering in the removable-device security space. There are many products rubbing shoulders in this area, and the basics are pretty well covered. StorageSafe is not aimed at high-end environments, with key distribution and management features, but at quick and basic everyday data protection, which it does well.

Clearswift's MIMEsweeper for Web applies the company's email filtering system to the internet. It will install on a single Windows 2000/2003 server and works as a web proxy, scanning all requests.

Finjan Software's NG-5100 can be deployed as a single box, but the system supports a distributed environment where one appliance serves as a policy server, while others can scan through load balancing. It can sit as either a standard web proxy, in which case you have to reconfigure all client computers, or as a transparent web proxy.

The smallest appliance on test, Blue Coat's ProxySG 200 is half the width of standard rack mount equipment and uses a notebook-style power supply. Rather than a pure web filtering appliance, the ProxySG 200 is a full-fledged web proxy, with URL filtering built in. This makes it quick to process requests and gives you a single point of management for your proxy and web filtering.

St. Bernard's iPrism 1200 is a 1U rack-mountable appliance. With clearly labelled network ports, it is very simple to connect to the network. St. Bernard also sells the iPrism 3000, which is aimed at larger organizations, with Gigabit Ethernet.

Fortinet's FortiGate-800 is the company's mid-range firewall. It uses FortiOS 3.0 (this is a correction from the incorrect v2.5 printed in the original article) and comes with antivirus and intrusion prevention as standard, both regularly updated.

The 2100 CF is a dedicated content filtering appliance. It has three Fast Ethernet ports – two sit transparently inline with your internet, the third is a dedicated management port.
