The Best Network Monitoring Software **Rating:** 5.0/5.0 stars **Reviewed by:** S P. | Undergraduate, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** February 21, 2025 **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. ### 2. I love glasswire **Rating:** 5.0/5.0 stars **Reviewed by:** Walter C. | CTO, Small-Business (50 or fewer emp.) **Reviewed Date:** February 18, 2020 **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. 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 ### 3. User friendly firewall with clear GUI. **Rating:** 5.0/5.0 stars **Reviewed by:** Paul S. | IT Manager, Publishing, Small-Business (50 or fewer emp.) **Reviewed Date:** February 18, 2020 **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. ### 4. GlassWire Firewall **Rating:** 5.0/5.0 stars **Reviewed by:** Carmine A. | IT System Administrator, Small-Business (50 or fewer emp.) **Reviewed Date:** December 29, 2021 **What do you like best about GlassWire Firewall?** It is very easy to install and configure. **What do you dislike about GlassWire Firewall?** Some of the alerts are false positives that need to be investigated. **Recommendations to others considering GlassWire Firewall:** It is an excellent third-party firewall solution that gives you an extra layer of security so that your workstation is not low-hanging fruit for the bad actors. **What problems is GlassWire Firewall solving and how is that benefiting you?** I am enabled to track and block unwanted hosts services trying to connect to my workstation. ### 5. A very useful tool with a few caveats. **Rating:** 4.5/5.0 stars **Reviewed by:** Jacob V. | Service Desk Analyst, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** February 21, 2020 **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. 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. **What do you dislike about 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. **Recommendations to others considering GlassWire Firewall:** If you have knowledge of networks and what a more detailed breakdown of your activity then GlassWire is where to look. **What problems is GlassWire Firewall solving and how is that benefiting you?** It did help me see where some hidden programs were causing some unnecessary network draw and remove them. If needing a detailed network outline and consumption and a meta amount of control over the network this is a clear contender for 1st place. It has made network overview much less of a hassle in trying to see what is drawing what. ### 6. You control what you want talking to the internet (period) **Rating:** 5.0/5.0 stars **Reviewed by:** Chris W. | Chief Executive Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** February 19, 2020 **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. 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. I would say It is a must for people looking to secure their networks. **What do you dislike about GlassWire Firewall?** The few downsides I would say it does offer is not being able to block programs from connecting to some IP addresses or subscribing to known lists of IPs. When using "Ask to Connect" the user needs to have a deep understanding of what needs a connection and what is unneeded. It's also lacking any kind of features that would allow me to view or monitor what kind of data is being sent in and out. Overall, these would not stop me from using the software. **Recommendations to others considering GlassWire Firewall:** If you want to have the most control of what is talking to what online or in your network. This is it. It has a great free version with many of the features with only a few amazing features gated. **What problems is GlassWire Firewall solving and how is that benefiting you?** The best thing is you can stop threats before they can even get their payloads downloaded. Then you can see right where they are hiding and kill them. ### 7. Best network analyzer. Complete and friendly. **Rating:** 5.0/5.0 stars **Reviewed by:** Felipe Glauber Lima R. | Assessor de Comunicação das Categorias de Base, Mid-Market (51-1000 emp.) **Reviewed Date:** February 18, 2020 **What do you like best about GlassWire Firewall?** GlassWire has one feature I've never seen before: a mini viewer available over my desktop apps. The firewall works great and seamlessly on Windows. The Elite edition allows me monitor unlimited remote clients, which is another unique function. The log of data is one of the biggest ones. It keeps an year of traffic, apps updates and consumption by protocol data. I used to pay for antivirus, but they never permitted me to know when my connection is being used by third-party apps. Now, with GlassWire only, I know and can investigate inappropriate use of my bandwidth by unknown sources. For streamers, it's a key tool. Well, I need to highlight the visuals. GlassWire is beautifully developed and comes with good skins options. **What do you dislike about GlassWire Firewall?** Glasswire doesn't allows me to customize the units for bandwidth measurement. It would be awesome if the user could choose between, MBps, Mbps or, even, kbps. Some kind of integration between GlassWire Mobile and desktop would be cool. Imagine users using smartphone as remote viewer! Incognito mode doesn't explain what it's made for. Doesn't have a GAME MODE. Doesn't have a STREAMER MODE, allowing user to choose specific apps to use network with priority, similiar to a "QoS via software". The app doesn't have an AUTO DARK MODE for night times. It would be great if users can set different skins for different hours of day. **What problems is GlassWire Firewall solving and how is that benefiting you?** GlassWire replaced antivirus, giving more speed for my PC and a more transparent network analysis. ### 8. GlassWire - a great add-on to Windows Firewall **Rating:** 5.0/5.0 stars **Reviewed by:** Chris T. | President, Ottawa PC Users' Group, Mid-Market (51-1000 emp.) **Reviewed Date:** February 14, 2020 **What do you like best about GlassWire Firewall?** I think the best feature of GlassWire is the ability to have programs checked at VirusTotal.com before they can access the Internet. Beyond this, GlassWire makes it simple to prevent even non-malicious programs from accessing the Internet. This is great for programs that may leak personal information to the Internet. **What do you dislike about GlassWire Firewall?** There is nothing I dislike about GlassWire. It is a solid, effective product. **Recommendations to others considering GlassWire Firewall:** Try it! There is a trial version available and only by using it will you truly understand just how powerful this program is. It is easy to set up and configure. Reporting on network activity is clear and easily understood. **What problems is GlassWire Firewall solving and how is that benefiting you?** Programs on my PC are checked at VirusTotal.com before they are premitted to access the Internet. If I get some new piece of malware on my PC before my chosen anti-malware program detects it, hopefully one of the more than dozens of anti-malware programs at VirusTotal.com will detect it. This is a fantastic capability. I also use GlassWire to block some programs from accessing the Internet when I feel there is no good reason to allow them to. ### 9. Glasswire helps me track my home office traffic better! **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Small-Business (50 or fewer emp.) **Reviewed Date:** February 18, 2020 **What do you like best about GlassWire Firewall?** I use glasswire to monitor my homelab, where I try some of the craziest things. I love Glasswire's ability to dig deep into the past - I can easily discern between new and ongoing trends, and see what is really using my bandwidth over time. I've been able to easily identify and remove unexpected talkers that I had long thought removed, or block them. Since I can easily see both incoming and outgoing traffic, I'm able to gain better insight into what is actually going on behind the scenes. I haven't seen any AV conflicts and that really makes me happy. **What do you dislike about GlassWire Firewall?** I would really like to be able to see (or at least access) glasswire data from a local control console from one of the machines within my network - it's annoying to have to go from machine to machine. Glasswire also has the potential to introduce conflict with VPNs like NordVPN, as well as some command and control programs such as Tanium or Bigfix - it concerns me that the recommended techniques for bypassing some of those conflicts, such as with VPN, may reduce functionality. **What problems is GlassWire Firewall solving and how is that benefiting you?** I'm able to track down anything from minor undesirable activity up through major talkers on my network, and look at things both in real time as well as extensive historical perspectives. By reviewing this activity in Glasswire's different activity views, I can determine where to focus my energies significantly more easily than watching things with only OS-native and free analysis tools at my fingertips. This is a significant benefit for me as one of my side-goals in my home lab is to optimize network activity for the products I'm supporting, so Glasswire helps with that a lot. ### 10. Excellent Tool **Rating:** 5.0/5.0 stars **Reviewed by:** Steve B. | President, Managing Owner, Small-Business (50 or fewer emp.) **Reviewed Date:** February 18, 2020 **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. ## GlassWire Firewall Discussions - [What have you found to be the best software to integrate with GlassWire to give a rounded out network protection?
