Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

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.

Quotes from Members

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

Pros

"It helps us get to root cause quickly. With utilization and consumption of bandwidth, we can usually see what application is taking as much as they should (or shouldn't), then account for it accordingly."
"We are attracting customers in good sized numbers as we advertise and market this solution."
"It has cut our group's troubleshooting time down significantly, e.g., depending on the issue, what would normally take maybe a couple of hours will now take minutes."
"This solution has cut our overall troubleshooting time, sometimes going down to a few hours over what might have taken one to two days to fully troubleshoot an issue, and it has helped to increase our application uptime as we try to keep the five nines."
"The solution has helped to increase application and network uptime, reduced our mean time to repair significantly for application and network issues, and cut our overall troubleshooting time from an hour down to five minutes."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"I found PRTG Network Monitor very useful for troubleshooting and monitoring the utilization of either the network or server."
"Accessibility, ease of use (Web GUI, MobileApps). In general, compared with other software"
"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 will take care of all your monitoring needs, pretty much, but just be conscious of scale."
"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."
"The sensors and remote probes are phenomenal. We use them for all of our global sites. The problem with our global sites are that they are all VPNs. If the link goes down, you can't monitor other solutions, as it just goes off the grid. Having remote probes allows them to still carry on and get the information that we need when it comes back up, sending the information to us."
"We've managed to cut down on our P1 escalations by around about 70 percent."
"The most valuable aspect is the diverse range of features it offers."
 

Cons

"The stability depends on who is using the tool, because you only can get as much out of the tool as you put into it. There are a lot of patches for this particular environment, so you have to keep on them. If you lose track of them, then the product is not useful anymore."
"We don't use the single pane of glass view, even though we own it."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"I would like to see an improved level of stitching between IPs."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"It's not able to communicate with our probes."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM."
"Sometimes, we can't access it."
"They should work on syncing the solution with Gmail."
"There is room for improvement in this solution for the performance and third-party monitoring protocols. They need to be updated to the latest ones."
"The solution could be better and faster when it comes to performance."
"The database needs improvement."
"Its price can be better. Its price is a problem for us because it is in dollars, and there is a high conversion rate. In terms of new features, it can have BGP monitoring. It should also have a dashboard and maps editor."
"For smaller networks, I would recommend this solution. That said, if the network is complex, I would recommend a company evaluates another product instead."
"The dashboarding definitely needs improvement."
"PRTG Network Monitor needs to show bandwidth utilization in proper graphs. It isn't easy to learn."
 

Pricing and Cost Advice

"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"This product could be cheaper."
"The price is a little high."
"I would like it to be more scalable with less spend."
"Right now, the smallest sensor pack that they have is just a bit out of range for me, as a business. This kills me, as I need the product. Therefore, there is always a balance between needing to buy it or continuing their free version."
"Licenses are very expensive, so I would like to see cheaper licensing."
"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."
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"The scalability is there, but smaller companies might need CAM software to be able afford the product."
"The pricing is very low compared to other solutions."
"The price of PRTG Network Monitor is reasonable."
"Our licensing costs are 10,000 euros over three years."
