Netgear is better known for its network routers and switches than its security appliances. Karl Wright takes a look under the hood of the ProSecure UTM150 to see if the new unified threat management appliance is right for you.
The Netgear UTM 150 is a unified threat management device: an internet gateway, with a built-in stateful firewall and subscription web and email filtering. It sits between your broadband connection, or connections, and the internal network.
Set up is instantaneous; simply plug in your broadband device. The UTM150 has four WAN ports: so if one internet connection goes down, it switches immediately to a backup. Alternatively, you can configure it to load balance across all available bandwidth, helping to get the highest speeds – and best return on investment – from your broadband.
The firewall’s basic configuration is to allow all outgoing connections, but only let incoming connections that have been requested by a client behind the firewall. You can easily customise this using the web interface, allowing or blocking specific services. We tried blocking and allowing a range of services, for the whole network, for certain device groups on the network and by schedule – with perfect results every time.
Web- and email- and spam-filtering only works when you subscribe to the online filter services bundled with the product. A year’s free subscription is included with the UTM, after that you pay $1062 (approximately £660) for a 1-year account and $2710 (approximately £1,685) for a 3-year account.
Content filtering worked well, but sometimes threw up false positives. It's easy enough to remedy using whitelists though.
URL filtering worked all the time, without any exception. Content filtering worked well, but sometimes threw up false positives. For instance, it classified an online human resources booking system as a “computers and technology” site, which was therefore blocked under the filtering scheme we had set up. Overall, however, the number of false positives was low, and it’s easy to put a site on a whitelist if you want to make an exception for it but still keep your general rule.
Email antivirus filtering efficiently stripped out .exe and other suspicious files, as we’d specified, and scanned all outgoing messages without noticeably delaying their being sent. We did, however, have to remove the [MALWARE FREE] notice that the device, by default, adds to all outgoing mails it scans.
