Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Madhan Cs

Senior consultant at Cambridge Institute of Technology

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration

PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I have no regrets using this product, I am very satisfied for what I paid for it and for the things I am able to do with the product."

"Go take a look at it. It's a great product and has great capabilities."

"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."

"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."

"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

"If you have the opportunity, I would strongly encourage you to get it, because it makes the IT experience easier and more flexible, by providing the ability to see things in your networks like the directory packet label."

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

More Observer GigaStor pros

"PRTG Network Monitor helped us detect the failing RAID controller before it completely collapsed, allowing us to avoid potential data loss."

"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."

"The auto-pause for sensors during maintenance windows is awesome, as there are no false alerts till now and the built-in SNMP tester tool has saved me multiple times during setups, making PRTG Network Monitor a one-stop monitoring solution for my industry."

"Its initial setup process is fast and easy."

"The technical support seems to be quick, clever, and has a comprehensive knowledge base online, which is fantastic."

"The most valuable feature is the notifications, as long as you spend time and think about what and when you want to be notified, it's always accurate, it is always there, and I find things out before my Internet provider."

"This solution makes it easy to group devices, and it is easy when it comes to dependencies of devices, so if your router goes down, the three or four switches behind it will automatically be paused so that you don't get multiple alerts."

"Stability-wise, I rate the solution a ten out of ten."

More PRTG Network Monitor pros

Cons

"I would like to have more than 4TB of storage available in the portable version of this solution."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"The Observer Console UI is consistent and stable, but could use some updating to be more modern."

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."

"The dashboarding definitely needs improvement."

"PRTG Network Monitor is okay to use, but you'll need some time to analyze the data. If it can automatically locate or identify the problem area, it would be more helpful to users."

"In a very few cases, customers want more detailed reports, which we cannot meet."

"Sometimes, our PRTG Network Monitor system crashes and a lot of sensors go down."

"PRTG Network Monitor could improve interaction with customers by offering direct support involvement instead of just mail responses."

"The technical support needs some improvement. The response time is slow, we normally get a response the next business day for urgent issues which is long time."

"PRTG can fix that, but it's only good for small workloads."

"Limiting the bandwidth per host would be very good; however, that's beyond the capability of the PRTG."

More PRTG Network Monitor cons

Pricing and Cost Advice

"It's quite expensive."

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."

"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."

"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."

"The scalability is there, but smaller companies might need CAM software to be able afford the product."

"The price of PRTG Network Monitor is reasonable for the features that the solution provides. They charge you per monitoring, not per node, it is per port that you need for a device."

"We are satisfied with the price."

"The pricing for PRTG in our case is reasonable because we have a lot of applications to monitor within PRTG. It is not that expensive."

"It is about £4,500 for the first year, then about another 15 to 20 percent annually after that. So, we are looking at about £1000 running costs a year. When you think about how much an outage costs per minute, it's negligible."

"Because we are only on the free version, we have a limited number of sensors. Therefore, we are not monitoring as much as we want to be to obtain historical information."
