Customer Ratings & Reviews

Hardware Set-up: Cujo, Arris Surfboard 8200, Linksys Velop (3 Pack), Linksys SE3005 (5 Port Switch), 4TB WD MyCloud, and a Philips Hue Bridge. Setup was fast, easy, and seemless! Within 10 minutes of device setup Cujo customer support called just to make sure everything was going smoothly. The perfect smart firewall and amazing customer support!

Fast and easy setup...it took about 15 minutes to fully configure. The longest part was when my router rebooted for the redirection in the DHCP server. I took a speedtest before the setup and got 282 Mbps download and11.9 Mbps upload. Once Cujo was inline with my network (bridge mode), I received 34 Mbps down and 3.63 Mbps up. That's a 87.9% decrease in speeds!!! Needless to say, I will not be keeping this. If you're paying for Gig and can live with an 88% decrease in speed, then this is the firewall for you. For everyone else...it's not worth wasting your time. The only reason I'm giving this 2 stars is because of their app, which seemed very user friendly. Loaded with information on attached devices and threat statistics, the Cujo app seemed to be very informative without needing a Cisco networking certification.

As a computer savvy person, but by no means an IT guru, I was thinking products like this were simply a gimmick or just an unnecessary expense. But after the latest credit bureau hack I was thinking that maybe there is something more I should consider doing. My router is secure, and I've done the port scans and such, plus my computers are protected with a firewall, anti-virus, etc. What I hadn't considered was all of the Internet of Things (IOT) that do not have that same thing like a firewall or antivirus protection. Couple that with the fact that my router was not "smart" and didn't simply know what to do with inbound requests from some IP addresses. I set this up, easy enough. Got a phone call after setup, and the guy said he wasn't sure if I hooked it up right but I followed the directions and the device was seeing all of my devices, so all seemed okay. Days and days went by, with no warnings of any kind. So I was thinking maybe this was really unnecessary, until yesterday. Yesterday I got a warning about an intrusion attempt into one of my security cameras. Since it cannot defend itself per se, other than a strong username and password, I had a lightbulb moment that this was a very necessary product. Cujo BLOCKED the suspect IP attempts and that put my mind at ease. Apparently the hard working folks at Cujo are looking at many angles to determine what is safe, and what isn't. An outside IP from a known problem location, are blocked.....very cool. This is all you needed to know if you wonder if it worth it! I don't use the parental control/user assigned stuff, but may at some point. It was more of a way to prevent anyone from accessing my home network through those IOT devices that aren't able to protect themselves with anything other than a password. This unit comes with a lifetime subscription so I won't have to pay anything each month to get updates. I understand now, that this is a necessary thing for any home network to have (or small business) to prevent unwanted intrusions. This unit looks great, works great, and certainly something I wish I would have gotten sooner. This is about as plug and play as you can get, so even if you are a bit clueless about this stuff, it will do its thing and let you know of any concerns. Oh, if you were wondering if this was some kind of trick or scam from the people at Cujo, I can assure you that when I did a lookup of the IP address, I found it had been reported before as a problem IP address.

When i first got this, the app interface was different from what it is today, after a few updates from the Cujo team. This changed my perception of the product. Why? Because i saw how much total traffic was being filtered and now that feature was removed. That makes me worry that the system isn't working as hard as it should - if at all. You can look at how much traffic was scanned over the last 24 hours, but not any more than that. The permissions thing, which allows you to lock out certain categories for certain people, doesn't appear to be working properly. I engaged it for myself and tried some sites like gambling, and it let me go to them. It wasn't a one or two thing, it was many. That tells me this feature is not working properly. The part that I love is that the unit was telling me someone was hacking (multiples) or trying to get into one of my interior security cameras. That gave me alot of confidence in the product.....but with traffic stats removed, I don't know easily if it is really still working. Regardless of whatever else you think you have for security on your network, unless it is a hardware firewall, you are vulnerable. This gives you that.....and you can buy a more expensive version with no monthly fees and unlimited (lifetime) coverage of updates. I'm banking on the fact this will pay off long term vs. paying a monthly fee. Buy one, even if it isn't this one, so you can some security on your network. A smart firewall like this will protect you from inbound attacks you didn't even know were happening. Your router has a firewall, but it isn't smart....this is and helps protect you. The Cujo team needs to get back to the basics with the app as it appeared weeks before when I bought this....I wrote to their support but nobody ever wrote back....that concerns me, that they aren't listening.

This product was easy to set up and use, found several hacking attempts on day one and now are a thing of the past. The Threats found are a real eye opener as to all the malware happening all the time. Cujo is stopping them and now my IoT devices are also safer. Highly recommend this is every home.

I have now purchased eight of these for eight small offices, where there are not too many folks - and this is a terrific line of defense against external malicious attacks. The Cujo devices learn your activity and habits over time and adjust accordingly. They are constantly updated on their own - and I have all of them registered onto one convenient app where they can be monitored and checked for anything suspicious at the offices. The app currently is only available for Android or iOS, however if you run an Android emulator on your Windows desktop, you can easily run the app and keep an eye on things, right on your desktop (the limitation on the apps is for security and safety, and was set that way by Cujo). I need to say that the team at Cujo are SUPERB - they are so eager to help with setup, troubleshooting - you name it! I very highly recommend that every home be with a Cujo as protection, and small offices as well! Terrific product, from a terrific company!

A product that takes over how your network communicates with the internet and in theory make it safer through machine learning. It is not easy to install, corrected by great help that is at your fingertips – real people call you back. Then just sit back and watch wow

Love this thing. Was able to see so many things including sites my girl was using, however it does not work with onhubs unless you put then in bridge mode which looses a lot of googles functionality which I was not okay with.

I have been a Cujo Firewall user for more than two months. From the install experience to daily use I am very satisfied with the product. During install, I had a small problem with the iPhone interface, I opened a ticket and a technician called my cell number and helped me to do the complete installation. In daily use, Cujo firewall caught that my Amazon, fireTV attempted to access questionable sites (22 times overnight). Amazon’s technical support told me to reload software. The same way Cujo stops Facebook to open Windows exploit sites, Adware, botnet sites It really works! I highly recommend Cujo Firewall

Tracks online web browsing and alerts very well in advance that the website could be a trap. Great thing is with one click on the Cujo App, the ability to lock out internet is a great plus - it is as good as all devices are offline. It is still relatively a new product and I hope for the price, they could add more security and features by releasing security patches and firmware upgrades to stay on top of the culprits. Catch me if you can is the game. I hope that Cujo keeps up with the good work. So far, well done CUJO.

I've had the Cujo device for nearly 6 months now and can say I'm really pleased with it. I was worried it might slow down my speeds but can say it does not. I had one issue and the cujo support team jumped on it faster than you can say "cujo". They are fast, knowledgeable, and eager to help. I was looking for a hardware device that would protect all of my IoT devices and glad I stumbled upon cujo

Cujo installed quick and easy with help from experience experts video chat in the Apo. Since then it just works, without any effort from me. New devices, blocked malware. All painless. Many threats are blocked on my network every month. I strongly endorse this company and this product.

This was a great standalone home firewall, but I opted for a router with built in security capabilities. I opted for the new ASUS Blue Cave instead. Less hassle to set up, with similar functionality in securing your home network and IOT devices.

I have been looking for a firewall/IDS/IPS like this for a long time. Cujo is working flawlessly! If you are concerned that you are not "technical" enough to install Cujo don't worry. Call the Cujo support and they will get you up and running in no time! My home network includes an Arris Modem/Router and an Apple Time Capsule (in bridge mode) that I use for backing up my Mac laptops. I use the wireless SSID from both devices. I connected Cujo to the Arris, and started the install process on my phone. The install threw an error and suggested I call customer support. I called Cujo support and after they asked a couple of questions, had me download Teamviewer so the engineer could see my screen. We had to make a few changes to DHCP on my router, rebooted Cujo, and then rebooted my Arris router. After the router came up, all my connected devices to include both routers, Nest and Hue IOT devices, mobile devices, and laptops were visible on the app! Finally, the Cujo support engineer did a short demo of the product by having me go to a "fake" website that Cujo sees as bad. Really cool! Thanks Cujo!

I asked my brother how to set up my new computer, and he said I must get Cujo to protect all my various computerized phones, laptops, and Rokus. Great product!

I'm not sure yet how well this is working but I will say that customer support was outstanding. I bought this during the holiday sales but just got around to setting it up. I started setting it up and then hit some trouble with connecting to my netgear ORBI router. I hate waiting on hold so I was looking around online reading about it when I got a call from Cujo Support. Simon remote accessed my computer and changed my router settings and got it running in 10 minutes. I'll update this after its up for a bit

Cujo has made my Internet useless - My top Download speed with Cujo is less than 1% of my speed when Cujo is unplugged. It has been almost 2 weeks since I asked for Help and they have offers no solution at all, other than to blame a router that I have installed with Cujo for a year. Nothing has changed on my router in months and without Cujo my Internet speeds hit the 100-120Mb/sec I should get. I know some people will think its an Experience issue - I am a Cloud Engineer and have been in IT for 25 years - I fully understand Transparent bridges, I have installed multiple Sonic Firewalls in Bridge mode, Cisco 9k's, Ubiquity, etc... This issue is something on their side or a change that happened. As of now, its a brick in my server rack - May just go with another product like pfSense or something similar. Attached pictures show the speed with Cujo and Without - again, been an issue for a month.

Nothing gets pass CUJO love that it tells on EVERYONE

I really didn't want to use it in DHCP mode because of hairpinning all my packets through a single LAN port but that's the only way this can be used if your router is also a wireless access point. Still, network benchmarks show no degradation so I'm reluctantly content.

I've been using open source IDS/IPS solutions for a while, but wanted something with more features and automation. Cujo fits the bill at a fraction of other solutions. What really sets them apart is their support, world class, whether for pre-sales questions, set up or tech support. You won't find a more professional, knowledgeable, or friendly help desk anywhere.
