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

"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"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."
"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."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"We use it for monitoring whenever we update a new circuit or site."
"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."
"Go with NETSCOUT."
"It is very rock solid, and we hardly have any hardware issues."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"The reporting module is easy to configure."
"The most valuable feature is the dashboard interface. It's very clean, it's very simple to use."
"The alerting is the most valuable feature. I also like the iPhone app. I get alerts in an email on the iPhone app."
"There was only one feature I liked about PRTG Network Monitor a lot, and that was bandwidth monitoring, though, in the newer versions of the tool, that feature is now a bit lacking. Pricing for PRTG Network Monitor is also not as expensive. It's a good tool, even for beginners."
"Stable solution for monitoring networks and bandwidth, with multiple functions and features such as NetFlow Collector, graphical monitoring, etc."
"You will not find anything cheaper that really does the job."
"PRTG Network Monitor is easy to set up. Within a few minutes, it is operational."
 

Cons

"The solution is not great, but it is not bad."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM."
"The single pane of glass feed still needs work."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"I'd like them to make the product more user-friendly."
"There is a timeout feature that we have been asking for awhile."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"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 would like a more straightforward ability to create dashboards and maps. The network maps should be a bit more flexibility in the GUI to do what we need to do."
"From time to time, you need to reboot the PRTG probe server."
"There are some vendor-specific sensors in PRTG Network Monitor, particularly for older hardware, that don't always provide consistent results."
"This product can be improved by updating the net flow interface. The one that is in place works – I can get all the information I need from it – but it is a little bit clunky."
"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."
"Sometimes, our PRTG Network Monitor system crashes and a lot of sensors go down."
"The most significant disadvantage of PRTG Network Monitor is that the dashboard for NetFlow is not user-friendly at all."
"The licensing policy needs more flexibility."
 

Pricing and Cost Advice

"The price is a little high."
"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 it to be more scalable with less spend."
"This product could be cheaper."
"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."
"The price is actually on the cheaper side. If you're going with the unlimited license code, it's very cheap compared to competitors unless you're going for something free, like Zabbix. But you get what you pay for, and it doesn't have the full suite of products or tools like SolarWinds or a ScienceLogic."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"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."
"In my company now, we are using the free version."
"The licensing fees are billed annually and there are no costs in addition to this."
"The price is pretty comparable."
"The pricing is not too bad. It's not massively expensive, and the ability to upscale or even downscale licenses every year is brilliant for us."
"Licenses are very expensive, so I would like to see cheaper licensing."
