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

"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."
"It is very rock solid. We hardly have any hardware issues."
"Go with NETSCOUT."
"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."
"From a troubleshooting perspective, it allows us to quickly search all data TAP points in the network and helps our network engineers get to root cause quickly."
"We have seen a lot of return on investment: We have been able to recover radios in the field, we know exactly what is going on, we cut down fines from the service commission, and we have seen a measurable decrease in mean time to know, cutting troubleshooting down by days as we can now see the issues."
"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."
"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. I find things out before my Internet provider."
"PRTG is relatively intuitive and fairly straightforward. It has net flow monitoring and that works all right. I would describe it as a decent middle-of-the-road solution."
"My opinion is that this solution is not very expensive."
"PRTG Network Monitor offers valuable features that save a lot of time as the reports are automatically available, and I rely on them because they provide proof during escalation, with exact downtime logs and related information."
"It helps the entire organization become digitally enabled."
"The most valuable feature is the ability to span multiple technologies and multiple vendors."
"It allows us to directly add individual VMs independently."
"It will take care of all your monitoring needs, pretty much, but just be conscious of scale."
 

Cons

"I would like to see an improved level of stitching between IPs."
"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."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"The NetFlow Collectors could handle more flows per minute."
"It can be scalable. It just costs too much."
"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."
"I'd like them to make the product more user-friendly."
"I have an issue with DFS, distributed file services... there isn't one by default. Taking into account the difference between DFS and DFSR as well would be great."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected. For example, the IAS sensor doesn't give immediate information, and the information you get from it isn't of good value. The web GUI of PRTG Network Monitor also needs improvement because errors keep popping up if it's not been updated to the latest version. What I'd like to see in the next release of the tool is end-to-end topology mapping for the business model, and that should be required. There has to be a technical map. Technical mapping and topological creation are missing in PRTG Network Monitor, so I would like to see those in the future."
"If PRTG could help me see the bandwidth for each host I have on my network, either for a wireless or a wired network, that would be very helpful."
"When it comes to third-party integration, one of the things we were looking at was putting some sensors onto our firewall, for instance. If there were a little bit more documentation and some step-by-step guides around that, that would be useful for us."
"Sometimes, it is difficult to drill down further to get information, e.g., if we saw spike in traffic, then we would want to drill down and find out what is causing that spike in traffic."
"The Desktop app is good but it can be really sluggish at times, especially when you're editing different elements."
"Dashboards can look cluttered on smaller screens, and the UI can feel crowded when there are hundreds of sensors in one group."
 

Pricing and Cost Advice

"The price is a little high."
"I would like it to be more scalable with less spend."
"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."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"This product could be cheaper."
"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."
"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."
"The ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable."
"The price is pretty comparable."
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"We are using the premium version of PRTG Network Monitor. The price of the solution is a bit higher than competitors but it is worth the extra money. However, it would be helpful if the price was lower."
"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."
"We are licensed for 2500 endpoints."
