NG Firewalls allow us to permit or deny applications we don't want to run. We also use content filtering, SSL inspection, and all the other things we run on the firewall to keep our clients protected and ensure they're not going where they shouldn't. It's a great firewall that works as intended.

The majority of our clients are very small businesses, and Untangle devices have been fantastic for these small clients. We've basically standardized our stack to just simply use Untangle. We include the hardware and the service option, which makes it very easy and affordable for us to just simply push that into the monthly per-user costing that we provide as a managed services provider. It's really a no-brainer. They're easy to use, and they're easy to set up and configure. Support is generally good about resolving any issues that we have. We haven't had any real complaints.

I haven't dug into the advanced features, but I think some of the advanced capabilities are probably where it lacks a little bit, with the filtering and firewall rules.

I do not know if I have seen any return on investment. It might be a little expensive if I need to make an external firewall or at my sites like DNS and web zones.

On their low-end appliance, they could have more memory and the largest storage space. The low-end appliance comes with a too-small hard drive, and it could use a little extra room. It only comes with about 4 gigs or 8 gigs of memory, and the hardware space is only 40 gigs, which is really small.

There is room for improvement in the logs. Like with Cisco, I can do almost everything and know almost anything about what's running. Untangle works very much out of the box. It's very user-friendly, but it's not engineer-friendly. So, it's good for a home user. For something fairly easy, but at the same time, with good technology to have at home, because at home, I'm not a millionaire or anything like that. So it's not like I'm worried to get hacked. I didn't want something like a Cisco firewall; it would be a bit overkill to have at home. So that's why I went for Untangle. But it lacks a few features. It's just a tick-box kind of thing. So they have apps and turn on and off the apps. The VPN's configuration is all very ticked. They have a few custom configurations, but it's not that much.

Whenever there are a large number of endpoint VPN clients, connectivity becomes slow.

We have a minor issue when assigning IP addresses in the ARP tables. You should be able to go into the ARP tables, look at the IP address and say, "Nope, they need to be on this side on this IP address." The ability to set a DHP reservation from the ARP tables would be great. It's no big deal, but it would be nice to have.

It does have multi-factor authentication in some areas, but I would love to see a more widely implemented version of that on the devices themselves.
