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.

Alerting precision has reduced incident response times and improved department-level network visibility

The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

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

Pros

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

"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."

"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."

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

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

"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."

"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."

More Observer GigaStor pros

"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."

"There is a simplicity to setting up the extra sensors. It's really easy for us to build infrastructure and start monitoring very quickly."

"PRTG Network Monitor has positively impacted my organization; before PRTG Network Monitor, it was very difficult to monitor a wide variety of sensors, but since implementing it, which supports numerous sensor types and protocols, it has become much easier for us to monitor servers, virtual systems, and cloud services to some extent."

"It is a very stable solution. There are no bugs, glitches and we have not experienced any crashing."

"One of the valuable features is the diversity of metrics available to us to monitor. It's all there, it's all in the box. It's all made very easy, by virtue of it being pre-configured."

"The most valuable feature of this solution is being able to see things graphically."

"I would be happy to recommend PRTG; I have no qualms with it whatsoever, it does what we need it to do and is flexible."

More PRTG Network Monitor pros

Cons

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

"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."

"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."

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

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

"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."

"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."

"It would be good if there were better graphical interfaces when you have it on multiple monitors... Because we have so many servers, things can get lost in the fog a little bit. Maybe having a better way of showing different geographies, Flash, etc., would help."

"PRTG Network Monitor can improve the reports."

"PRTG Network Monitor definitely has room for improvement. They need to change their strategies because it has become relatively expensive compared to what it used to be."

"I would like to see Office 365 monitoring. Essentially, it doesn't do it."

"I would like to see them take their graphing tools and convert them into a collector so that we can point telemetry to them"

"Needs ability to monitor standard notification time (notify after X time)."

"PRTG Network Monitor can improve Layer 2 and Layer 3 network maps and the GUI more user-friendly. Additionally, they should bundle the features so I can monitor everything on one particular device."

"Along with more room for automation, more room for advanced configuration can be integrated into the solution."

More PRTG Network Monitor cons

Pricing and Cost Advice

"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."

"It's quite expensive."

"The price of PRTG Network Monitor is more expensive than other solutions, such as OP Network Manager."

"There is a license to use PRTG Network Monitor and it is annually."

"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."

"We pay nothing for it. Its 100 sensors have allowed us to put a magnifying glass on some systems, providing an extra layer of detail. Therefore, our outgoing is nothing and our incoming is a lot of useful data that we can react to proactively."

"The pricing is okay and it is cheaper than some competing products."

"The licensing fees are billed annually and there are no costs in addition to this."

"The price is pretty comparable."
