Fantastic Firewall for your Phone!

As others have mentioned, we were inundated by annoying scam, robo, and fake marketing calls, at all times of the day and night. I carefully researched the options & chose the Guardian. As one of their early customers we had a few issues but the developer was outstanding about helping us through the setup. Options include a basic setup, plus many more optional features. One can manage a phone list thru the phone or via a laptop. Ours is working fine on CenturyLink DSL, and saved our heads from exploding during the past election cycle. An occasional "smart" robot caller gets thru but is quickly halted at the first prompt. A super slick product that performs well, and a great company!

I have been an IT consultant for over 12 years.  I have installed and maintainted easily over 1000 firewalls over the years.  The market for a good small business firewall is not very good.  Fortinets were OK the last I looked at one about 5 years ago, and so were sonicwalls, but overall nothing would wow you for the price range of $300-$400.  Back in the mid-2000's Secure Computing made their Snap Gear firewalls which were awesome and you could buy them for $300!  For business' with 50 users and even site to site vpn's they just worked great!  Then McAffee bought them and turned it into junk.

So I got going on Cisco's new SA series back in 2006.  I have installed dozen's of these things in both the 520 and 520w flavor.  They really do impress me with what they can do and their performance is awesome!  The things I like about them are that they can do trunking on their LAN ports, you can configure Vlans in them, (both of these features I do for wireless access points, create custom service rules (which is expected), and setup high availability by doing auto-failover with different ISP's.  I also have SA520's for customers that I installed over 6 years ago and they are still running strong!  So the longevity and robustness of them seem to be good!

Now... the cons on these firewalls.  The VPN configurations are just plain junk.  The SSL, Site to Site and peer VPN are all pure junk.  I can never get them to work and if I d0 the next firmware screws it up and it may or may not work at all... ever again.  More often than not I cannot get any of the VPN options to work.  I simply gave up on them.  Thank goodness we live in a Terminal Server world and data packets have outgrown VPN connections and made VPN's a thing of the past.  But if you are looking to utilize the VPN capabilities of this firewall DO NOT BUY IT!!!  The headaches are not worth it.  I recently tried to setup my first Lan to Lan (site to site VPN) with this series.  It just does not work.  I have two different SA520's, one with the latest firmware and one with an older firmware.  I could not get either of them to do a Site to Site VPN to an ASA 5505, nor could I get the two SA 520's to connect to each other.  The tunnel links up in both cases, but passing traffic through them is a nightmare and you will find forum after forum of other users simply giving up on them and moving up to a Cisco ASA series firewall to handle this need.

So in the end:  For the money these are the best firewalls if you do not have any VPN needs.  They are easy to configure and you can setup multiple Vlans and trunk the 4 ports on them which is handy for your private and public wireless cases.  Out of all them I have installed they are truly set it and forget it.  The gui is slow and there is no CLI.  I would definitely buy these for a single office with up to 20 users.  If you have any case where the business is a growing business that will go over 20 users or more than one site than spend an extra $100-$200 and get an ASA 5505 that you can grow into.

We recently moved pretty far out of town, and discovered we had almost zero cell service at our new home. After purchasing this product, and a pretty easy installation and setup, I had nearly perfect cell service! The installation instructions were very clear, so the whole thing went fairly quickly and smoothly. The items included with the booster, helped immensely with the way our house was made. The only two issues I have with this product, are 1: it overheats where the cable goes into the booster, so the metal gets really hot to the touch (we unplug the booster at night to give it a break), and 2: my cell signal will bounce from between two and four bars when my cell hasn't even moved. Both issues are not a reason for me not to recommend this product, nor are they too troublesome; they're just small imperfections, and that's perfectly acceptable. As long as the booster works (it does!), I can browse the web (I can!), and the booster remains working for a long time (I sure hope it will!), I don't mind a couple of small imperfections. This was MORE than worth every penny, and will pay for itself in no time - by saving us money on satellite internet (I use my cell as a wi-fi hotspot)...so yes, I absolutely recommend this product, and I am quite satisfied with it! Five stars is well-deserved, as I am so grateful for this product and being able to use the internet, and make/receive calls and texts, way out in the middle of nowhere. Oh, a lightning surge protector (not included) is VERY necessary, so make sure you (whoever is considering buying this product) buy one simultaneously, so you can install it with everything at once! We had to install it later, as we didn't have the right cable attachment, but it is on there and protecting away! I LOVE THIS PRODUCT.

Bought this to use overseas, knowing that the unlocked version for T-Mobile and Verizon were versions that work here in Asia on their 3G and (where available) 4G networks.  Lost my first one here after only 4 months of use, and was so impressed with its functionality, especially Touch ID when I'm on the run and need to do things one-handed on the fly to open the phone.  My one concern is how good the kill switch is here in Asia with a bunch of hackers and a huge black market for stolen/lost smartphones.  Is my sensitive information still safe after putting the iPhone into "Lost" or "Erase" mode from my iCloud account?

The Apps have pretty much covered more than the functions that I used to depend on my Palm Tungsten PDA  - yes I was using that one up until getting this smartphone earlier this year!  Especially critical are the Apps for language study here in Asia, such as Pleco and other dictionaries for Asian languages.

The iMessaging app makes it a lot easier to stay in touch even on the go with family and friends back in the States while I work here in Asia.  This is especially helpful with the need for VPN in certain countries if you want to access your GMail or Facebook accounts.  The latter websites can only be accessed with VPN, whereas iMessaging comes through without any problems and no VPN connection.

The only down side has been the limited battery power on a single charge if you have the Apps in background refresh mode.  Doesn't last much more than a day and a half at best.  Have bought an auxilliary mobile charger to bring along when I know I'm going on the road and will not have reliable charging opportunities.

Will hang on to this for as long as it keeps up with the rapidly upgrading mobile phone infrastructure in Asia!

This was so easy to set up. I just plugged in the cable from my DSL modem to the WAN port, plugged the cable from my computer to one of the LAN ports, plugged in the power and it worked. I also play Counter-Strike (Half Life) a lot but with the new flash upgrade (3.24 which the one I received from Amazon had) it works like a charm. I have left my ZoneAlarm firewall installed for the last 24 hours and not a single hit (down from dozens to hundreds a day). If you want to mess with it you can configure it in dozens of ways. The PPoE and the VPN options are worth noting since many DSL ISPs require you to use PPoE. The 4 10/100 switched LAN ports are what sold me. After rebate it is only a few dollars than a 4 port switch. Now I can use my work laptop on the internet without unhooking my home computer. I say BUY IT !

LOVE IT. I had to change a few settings on my router to make it work, I had to enable some security setting with the password, like WPA2 or something and then BAM it popped up on the WeMo app and all went smooth sailing and I rely on it to control my garden every day and night; with no worries!!!!

The app on android DRAINS your battery; but that is not talked about here really, and thats something the developers need to fix themselves for Android.

I rarely write comments but I would really like to recommend this one. I am looking for such product for long while to avoid stupid contract. I got it yesterday, it is pretty easy to setup, connection is good. Good coverage, the 4G light is green. Speed is awesome, even faster than my home internet. There is coverage in my company but is normal because there is even no mobile signal for my mobile phone in the company's building. The tiny device has good size, very tiny. It is better if it is thinner so I can put it into my wallet. I also got 1G when I create account and got another 1G when I activated the device and 100M that I don't where to get. This product totally matches my need. Awesome!!

If you plan to buy this, be prepared to be stopped and asked about your phone every 15 seconds! Its EXTREMELY easy to install, and looks awesome! Comes with all of the tools required to install it on your phone. Love it!

This firewall easily the best value out there. I found it very easy to configure - like easier than the sonicwall TZ400. (I have no idea why people complain about this software) Before I purchased this product, I have always installed sonicwalls. For most of my clients I would use the sonicwall TZ400. While I still like sonicwall, I like this a lot better. This is way easier to set up, it is way faster, and it is also more cost effective. The setup on this thing is awesome. I feel like the setup menu can look overwhelming for someone who does not look at firewalls a lot. I wouldn't say it is a beginner firewall... but it is still not hard to understand after a little reading. If Zyxel keeps releasing amazing products like this, I will never buy a sonicwall again.

This is a great product. Installation was super easy in my Windows 10 64Bit laptop. Just plug and play! Files transfer via this bluetooth is awesome using my android phone!

I really recommend this product!

I purchased this and it works great, it's easy to connect and even easier to use, a lot safer as well than just using your phone whenever you need to.  Works great for the purpose!

This smartphone screen protector for my moto is a must have for anyone who owns an smartphone and does not want to have to pay for a new one in case they damage it or scratch it too much. First off, the installation is extremely simple and allows your phone to become very durable and able to last even high drops. I cracked my old phone and once I purchase my new smartphone I decided to not make the same mistake again and got a screen protector. I am extremely satisfied as I can tell this will protect my phone for its entire life. I highly recommend this to any smartphone user who wants a good product without paying an arm and a leg. I received this product in exchange for me to evaluate and share my experience. All opinions are 100% my own and they reflect my honest and unbiased opinion.

HYFY! Im a different kind of phone guy. Put this on my i5 and killed all my friends i5z off instantly! My only gripe is that you cant put a invis shield over it to preserve its SIckeness!

Best little Firewall ever.
Ubiquity has come a long ways
you cant go wrong.

Cons: It does not have monitor bypass mode.
so it needs to be the first device on your network coming from the internet modem.
maybe UBNT will add a bypass monitor mode to use it as a monitoring device but for now it not.
I recommend it for Home and Small Office.
Great price fast shipping,

Not a switch! Just for those like me who are new to networking. This firewall piece is awesome though. The unifi page is really east to use and with deep packet inspect I know what is coming and going. I set it up with the AP Pro and a basic switch I have.

Great product! Easy to install and works beautifully with infinite number of ring tones! Placed by front door on stone and brick wall and was a little concerned that might block connection. It did not and one receiver is about 30 feet away - no problem! Beats wiring up a doorbell which is what my old one was. Buy it, you'll love it!
