Anti-virus measures need no introduction as this comes courtesy of Kasperksy Labs. You can apply scanning to FTP, HTTP, POP3 and SMTP protocols so web and email traffic will be checked and apply these settings to any combination of LAN, WAN and DMZ ports. Infected files are destroyed if required and the Turbo Card gives the appliance enough oomph to scan inside archived files as well. IDP services cover all the common types of attacks and signature files for both this and the anti-virus component can be downloaded manually or automatically at specific intervals that can be as frequent as every hour.
Content filtering is a managed service provided by Blue Coat so the category database is maintained on its website and each web request from the LAN and WLAN will be passed across for checking. The pause is imperceptible during this process and you can pick and choose from over fifty categories to block and also stop ActiveX controls, Java applets and cookies from being downloaded. Transgressors can be sent a custom message in their web browser and be redirected to another URL as well. The appliance also maintains a cache of recent web sites visited for improved performance.
If you do opt for wireless access instead note that the appliance only accepts ZyXEL’s ZyAIR G-100 wireless PC Card which we successfully confirmed during testing. Plenty of security features become available as along with WEP and WPA you get support for a range of 802.1x authentication methods and the appliance can use an external RADIUS server or its own internal user database for authenticating wireless users.
Pricewise, ZyXEL is offering a comparatively good deal as you can buy the appliance and Turbo Card for around £369 (ex. VAT) or if you already have the appliance, the card combined with a one year IDP/anti-virus subscription costs £270 (ex. VAT). Content filtering will set you back £49 for one year and when the anti-spam service becomes available this will add a further £65 to the bill.
As a complete Internet security solution the ZyWALL 5 is a good value bundle that can be customised to suit a range of budgets. It’s very easy to install, configure and use and offers a good range of security measures. However, the fact that you have to choose between wireless access and the IDP/anti-virus measures is a minor irritation.
