    Something everyone should have....really

    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.

    Extra Layer of Protection.

    Posted
    Rick

    I purchased one of these a couple of weeks ago to replace my SonicWall TZ105. It was easy to setup. You have to know a little bit about how to get into your router and turn off DHCP. They provide the instructions and it's easy. If you are use to playing with your firewall and checking logs you're not going to be able to do that with Cujo. Cujo is a set it and forget it device. It works in the background automatically. Excellent for folks that want protection with no hassles. Since I've had it, it alerted me a couple of times about my son's computer and cell phone. That he was visiting malware sites and the connection was stopped. That was cool. The alert showed up on my cell phone. I tried running Zen Map against the IP addresses behind the firewall and was unable to detect any available host. So Cujo is protecting all the connected devices. If you have a household with a lot of IoT connected (TVs, Cameras, Thermostats, Alarm systems, phones, computers and tablets, etc) it's a good layer of protection. It also protects visitors that use your WiFi. I have a total of 28 devices connected (including friends that visit). And with all of that there is no latency (delay) getting to the internet. In the IoT environment and with the internet turning into the wild wild west, an extra layer of protection is nice to have and almost necessary. Go out and get one and add that extra layer of protection. It's worth the money. Rick

    Limited Capabilities

    I bought this product to protect my network against Dos attacks as stated in "Overview Security features". The firewall does not provide inbound/outbound traffic rules, block/allow applications (i.e. http, https, ssh, etc). It does not let you set data flow limits/priorities (Mbps) on your devices. The Cujo has two types of layouts, direct or bridge. I used the direct layout due to only having one router ("Orbi") and disabled my routers DHCP so Cujo could control and assign the IP addresses. The setup was configured correctly, but my router (Orbi) log still captured Dos attacks and Cujo did not. This was very disappointing due to Cujo exclusively being a "smart internet firewall". My Orbi router prevented the DoS attacks from entering my network but the numerous attacks overloaded my network and periodically shut it down. I bought Cujo to put up an additional firewall ahead of my Orbi router to prevent any attacks from shutting down my network but as stated before, looking at the Cujo logs this was not happening. In my opinion, the best thing Cujo is designed to do is prevent insider attacks (i.e. internal network malicious activity). While the product description states it can build a threat profile even for external attacks there was no evidence of that from the logs. Lastly, contacted technical support in hopes of alleviating this issue. Technical support explained Cujo cannot defend against Dos attacks as advertised and I should contact my IP provider (Xfinity) and see what they can do. They reviewed my routers (Orbi) log files for verification of the DoS attacks and never responded with any alternatives/ fixes to this solution. Tech support was very friendly but appeared to have limited knowledge of their product. Cujo was returned the next day.

    Offering Peace of Mind in the Connected Home Era

    Cujo is a great (relatively) consumer-friendly firewall for residences. INSTALL: Setup is pretty easy if you're tech savvy and have a basic understanding of your home network. CUJO support will even call to help you get up and running which is very nice for the less tech oriented folks out there. It's definitely not plug-and-play but that's to be expected with a firewall. BUILD: CUJO looks really sleek. It blends nicely with the rest of your gear. The status "eyes" are clever but are pretty bright. This can get annoying if you put it in your entertainment center. Luckily you can turn them off with the app. EASE OF USE: Once you get CUJO up and running it does all the work for you. The app is straightforward and easy for pretty much anyone to understand. The only thing I'm leery about is how many alerts it generates. Most make sense and seem like legitimate threat blocks and some don't. How can an Apple Watch attempt to visit a BotNet URL? Doesn't seem right to me. But hey better safe than sorry I guess. One of the best features is the new device alert. It's interesting to see all devices on your network and how much data they're using. You can even pause certain device's access which could definitely come in handy for parents. BOTTOM LINE: If you have a lot of IoT devices in your home, or even a lot of internet devices in general, a product like CUJO is rapidly becoming a necessity. In the age of cybercrime and the abundance of internet connected devices it's becoming less of a matter of "if" but "when", and CUJO aims to keep you safe with as little hassle as possible. Recommended.

    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.

    Great Firewall

    I bought my CUJO around 4 months ago and I am liking it. It blocked many attempts from untrusted sources from accessing some of my IoT devices. I would recommend this product to anyone that wants to make sure that their internet connected devices are safe at home. Pros: -Easy to use -Easy to setup -Support is very fast if you use the chat in the CUJO webpage -Companion app helps you identify the devices connected to your home. -Updates come often (at least one per month) and add functionality or fix issues. -CUJO's team is always trying to improve -You get notifications to your phone. -They have a lifetime subscription for a limited time. -I get around 5-15 notification from CUJO telling me that it blocked dangerous webpages or other kind of dangerous activity. -So far, I have not experienced any problem trying to access my IoT devices from outside of my home. -I have not experienced any problem with my internet speed since I installed my CUJO. -I have an Xbox One and a gaming PC and I haven’t had a negative impact on my gaming experience. Cons: -It can take around a week to get an answer from support if a ticket is opened for you. -The detection system doesn't have a constant behavior. Sometimes it blocks a webpage, but if you visit that same webpage some days later, it might not. This MIGHT be fixed with the latest firmware. -It doesn’t detect my managed switch and doesn’t completely recognize my router. Support tells me that they are working to fix this issue which is related to my router model/brand. They also tell me that this could be the reason why I don’t see a constant behavior in CUJO’s detection system. -Some times the notifications don't appear on your phone until you open the CUJO app. Notes: -If you are looking to change some settings, view logs, etc. You won't be able to do it with CUJO. This device is designed to be easy to use.

    First of all, having a Cujo on your Home or Business Network is like having an IT Specialist working around the clock for you protecting all your sensitive data! I have (2) 100 Meg Networks here at our store The Bling Box in Texas. Our entire lives and store information is internet based and we access sensitive data 7 days a week. Once I installed both Cujos, with the help of the awesome Video Tech Support Call Feature which rocks by the way, I was up and running! I'm running a Netgear Orbi Wifi Mesh Network on one network and an Apple Time Capsule Airport Extreme on another network and everything works FAST and PERFECT! The phone app controls everything and is pretty nice! I get updates every day of normal websites we all access that have malware, spyware, phishing schemes, ad ware all over them that are attacking us daily. Cujo slams the door on them and doesn't let them get what they want. I couldn't be happier. I plan on buying another one for our home too! They have a Facebook Group to you can join to stay in "the know" of what the company is up too and ask questions with like minded people about the updates that are projected for future software releases! One of my favorite things about Cujo is if a Cujo is attacked in California, it updates the cloud Cujo software of what is happening, and the master software sends out a notice/patch to all Cujos so they can now block the latest attacks going on every single day! I'm very happy! Take care - Jeremy at www.TheBlingBoxOnline.com

    Great idea, but regularly locks up

    Posted
    CentralPA

    This is my second Cujo. I have one for my personal use at home, and I just purchased this from Best Buy as a second for a family member. Setup was very easy: you literally just plug it in, launch the app, and a few seconds later, you're done! That's where the fun ends. Over the past few weeks, both of my Cujos have started locking up. When they lock up, they take the internet down with them. The only way to resolve the issue is to disconnect the power for at least ten seconds. I could forgive this if it only happened every few months, but this happens daily. In fact, it happened three times this evening. I do information security for a living, and I have confirmed that both networks are working properly. Once you remove Cujo from the picture, everything works perfectly. I've been going back and forth with Cujo technical support on this for over a week and haven't gotten anywhere. What was once great customer support has now gone bad. I can't help but notice that their support happened to drop in quality after I upgraded my other Cujo to a one-time subscription plan. I regret purchasing this and wish I could return it. While this is a great idea and a sorely needed product, I can't overlook this one critical flaw. The fact that their support team can't deal with this is the final nail in the coffin.
