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 is very rock solid, and we hardly have any hardware issues."
"The ability to troubleshoot customers' connectivity has been very beneficial."
"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."
"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 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."
"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."
"The product is stable. I have never had any issue where we have lost an InfiniStream, or visibility from that particular InfiniStream, throughout the bank."
"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."
"You will not find anything cheaper that really does the job."
"The alerting is the most valuable feature. I also like the iPhone app. I get alerts in an email on the iPhone app."
"We have asked questions of their technical support and they have a very good response time."
"It improves the status of my infrastructure, from networking devices to real-time machines."
"The most valuable features of PRTG Network Monitor are the threshold notification when certain traffic increases and goes beyond the defined threshold. The up and down status email notifications and other notifications are useful. Additionally, it is user-friendly, and customizable, and there are many features available."
"There is a simplicity to setting up the extra sensors. It's really easy for us to build infrastructure and start monitoring very quickly."
"To others who are interested in using this solution, I would recommend it, it's a decent product."
 

Cons

"There is a timeout feature that we have been asking for awhile."
"It's not able to communicate with our probes."
"I'd like them to make the product more user-friendly."
"The solution is not great, but it is not bad."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"It can be scalable. It just costs too much."
"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."
"Improvements in data storage flexibility, such as allowing customers to specify data retention periods, would enhance PRTG."
"The setup aspect of it and getting devices working needs improvement."
"The solution has to evolve as an end-to-end monitoring solution. It has to do better at understanding the application at the deepest level."
"PRTG Network Monitor can improve by adding prevention and detection features."
"If they are looking for complex reports, I will say stay away from this product."
"I would like to see more updates available in this solution."
"PRTG Network Monitor could improve by having a feature to allow uploading of preset standard network switch configurations and the ability to monitor the SLA configuration, such as uptime for the switches or internet connectivity. This would be very useful."
"The clustering aspect needs improvement, as there is a bit of confusion about you do when hit that 5000 probe mark."
 

Pricing and Cost Advice

"The price is a little high."
"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 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."
"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."
"I rate the licensing for PRTG Network Monitor an eight out of ten."
"We pay for a perpetual license and we have a support fee."
"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."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"If you are not too sure about it, try the free version. Then, if you like it, you can go to the paid version and roll it out."
"Our licensing costs are 10,000 euros over three years."
"PRTG Network Monitor is very expensive."
