The Best Network Monitoring Software
What do you like best about GlassWire Firewall?
The best thing about Glasswire is that it is very easy to use and it has more user-friendly interfaces. So we can monitor our network usage by just looking at the "Graph" or "Usage Details" interface. In the free version, we can monitor our data usage in the last 5 minutes, 3 hours, or 24 hours.
What do you dislike about GlassWire Firewall?
Nothing special. Actually, I'm very satisfied with GassWire.
What problems is GlassWire Firewall solving and how is that benefiting you?
So basically, I use GlassWire to monitor my network usage. I have limited internet connection. So I need to manage my data package for the entire month. By using GlassWire, I can get an overall idea about which apps on my laptop use more data and, according to that, adjust their usage.

A very useful tool with a few caveats.
What do you like best about GlassWire Firewall?
The break down of the network activity is one of the best that I've seen from other network activity scanners. Not only does it help you see what programs are pulling from the network but also how much. Being able to turn off and on specific programs is a real help when troubleshooting. Since this is available for multiple devices and OS's you can keep track of your digital footprint as it were. Whenever anything is behaving questionably there is even the feature to have that program analyzed for any virus or malware definitions.
What do you dislike about GlassWire Firewall?
The most helpful aspect that I have found is being notified whenever a new service starts using the network. If you haven't added any new programs and something starts to connect you know something is up. An upside is that everything is all in one place and easy to get to.
Recommendations to others considering GlassWire Firewall?
The pay-per-month income setup is not a favorite of mine. As these programs are great for what they can do by keeping you on such a program it will inevitably become a problem for some as it cannot fully take over for an antivirus. If using with another antivirus it would yield some serious protections against intruders into your system. But on the other hand if you could only choose one many would opt for the antivirus protections since this has no real time scanner.
What problems is GlassWire Firewall solving and how is that benefiting you?
If you have knowledge of networks and what a more detailed breakdown of your activity then GlassWire is where to look.

User friendly firewall with clear GUI.
What do you like best about GlassWire Firewall?
Fast, easy installation, excellent user interface - put simply, it just works! The user-friendly interface is excellent for both skilled and non-skilled users to learn the state of the desktop internet connections. It keeps us constantly updated with any necessary alerts and goes a long way for peace of mind. Glasswire is much more configurable than those regular standalone firewalls; it lets you blacklist connections specific to your own work environment. GlassWire enables to keep track of our mobile carrier data usage and Wi-Fi Internet activity which is great when our team are working remotely. I would not hesitate to recommend this product to both smaller businesses, teams and personal users.
What do you dislike about GlassWire Firewall?
I am very satisfied with this product and have no dislikes at this time. We haven't needed to contact the support team yet so cannot review that part of the service.
Recommendations to others considering GlassWire Firewall?
It's a no-brainer purchase for personal or small team firewall protection but if you are hesitant to buy - you can always trial it and then upgrade to the paid version, it's an excellent protective and diagnostic tool - though it shouls be remembered that this is only one tool in the toolkit necessary for protecting our work environment nowadays. For large scale corporate use you should check alternative offerings for comparison before deciding to purchase this.
What problems is GlassWire Firewall solving and how is that benefiting you?
We're using GlassWire to monitor and control program access to the Internet, saving on bandwidth and enhancing desktop security. We can easily filter desktop and mobile web traffic.

Previously I had to check data and network usage on each PC but now thanks to glasswire I do it all on just 1 PC I love glasswire
What do you like best about GlassWire Firewall?
There's so much to love about this software. I love how I can easily check what software is connecting to the internet, how much data they are using and how it breaks down between local and external traffic. I can even view the hostnames to which each application is connecting to.
What do you dislike about GlassWire Firewall?
Nothing really. Maybe the constant popups to upgrade to a paid package on the free version. I didn't have much trouble setting up Glasswire but i feel that i may be missing out on all it's benefits because of lack of some sort of tutorial or on-boarding process in terms of how to use the software.
Recommendations to others considering GlassWire Firewall?
A wonderful software especially considering that it's free. Gladly paid for the Elite licence for more features
What problems is GlassWire Firewall solving and how is that benefiting you?
I use Glasswire to monitor traffic on my PC and Android phone. I also use it to monitor about 10 computers connected on a network at work. It's proven to be a great time saver.

You control what you want talking to the internet (period)
What do you like best about GlassWire Firewall?
When I first downloaded Glasswire I didn't know what to expect. It was still very young and nothing like it had been developed to my knowledge. However, over the years I have installed it as one of my first applications on my systems.
What do you dislike about GlassWire Firewall?
Recommendations to others considering GlassWire Firewall?
Glasswire offers so many amazing features. The paid upgrade and the "Ask to Connect" feature, it is a god sent and must have. Being able to see usage on metered connections is grand. The ability to see which devices are connecting to your network instantly is also amazing. It also alerts you to software upgrading, internet outages, and so so much more.

Very good diagnostic Tool
What do you like best about GlassWire Firewall?
I like that it shows network traffic for different apps - you can see when an app is sending data or receiving data if you are trying to work out a bandwidth usage problem. The display and readings are very intuitive. Quick and easy setup.
What do you dislike about GlassWire Firewall?
Firewall is now a premium feature - that's a shame.
Recommendations to others considering GlassWire Firewall?
This is good for in-house IT Support Staff or Freelance IT Consultants to trouble shoot network problems for speed issues and data leakage.
What problems is GlassWire Firewall solving and how is that benefiting you?

Excellent Tool
What do you like best about GlassWire Firewall?
Glasswire gives me real-time information about everything that is going on with my computer. The firewall function is extremely useful and allows greater control over access to my system. Creating the ability to monitor usage graphically allows users the flexibility to discontinue programs that are non-essential. Real-time alerts let me know if I need to take action regarding a connection that might be harmful. All in all Glasswire is an essential part of my ongoing systems usage.
What do you dislike about GlassWire Firewall?
So far I haven't found anything that I dislike about Glasswire It doesn't take up much room on my system and operates smoothly in the background until needed.
Recommendations to others considering GlassWire Firewall?
I highly recommend Glasswire for all your system needs.
What problems is GlassWire Firewall solving and how is that benefiting you?
Potentially dangerous internet activity. The alert system has benefitted me greatly. It allows me to ascertain whether or not to continue with a connection or disconnect as a matter of security. It also has shown me programs that I can discontinue to allow better usage of my system memory.
