Network security can almost be a full-time job these days, especially if you have lots of users to look after. To start with there’s the firewall to manage and, increasingly, one or more VPN servers for secure remote access. Not to mention all those antivirus, anti-spam, anti-spyware and content management tools, now considered essential in the fight against Internet intruders. However, there are products that can help reduce the workload, such as the ZyWALL UTM range from ZyXEL, which provides most of what you need in a single, easy to manage, box.
