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's an easy product to set up."
"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting process."
"The most valuable features are speed and cost."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"When we have mobile operators who are signal partners, where one is the roaming host and another is the roamer, we are able to see their traffic. Their packets are able to detect if any faults to develop, and at what point they fail."
"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."
"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."
"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."
"The technical support seems to be quick, clever, and has a comprehensive knowledge base online, which is fantastic."
"PRTG Network Monitor helps us quickly and easily discover a large number of sensors, so we can spend minimal time monitoring customer sites."
"Stable and scalable network monitoring tool. Installation is simple and straightforward."
"This solution provides us with the needed feedback on our IT infrastructure. It allows us to grab all the information from a single point of view."
"We like the alerting system, the SNMP monitoring and the customization of the bandwidth."
"I found PRTG Network Monitor very useful for troubleshooting and monitoring the utilization of either the network or server."
"PRTG Network Monitor is easy to set up. Within a few minutes, it is operational."
"The product is easy to use and the web interface is fantastic."
 

Cons

"We don't use the single pane of glass view, even though we own it."
"There is a timeout feature that we have been asking for awhile."
"The NetFlow Collectors could handle more flows per minute."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"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."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"The single pane of glass feed still needs work."
"It's not able to communicate with our probes."
"The user interface could be more modern as it is quite dated. PRTG Network Monitor can sometimes be too detailed and cluttered at the beginning, making it heavy to use."
"It probably has this already, but if it had a mobile app that would be helpful. For example, on a day like today when I'm out, if I could just fire it up and see green, green, green, green, green or red, that would be good."
"PRTG Network Monitor can improve by adding prevention and detection features."
"Maybe in the future there will be room for improvement, but currently, there is nothing pressing that I can think of"
"In our organization, we encounter performance issues with our PRTG probe service. I saw documentation from the vendor or Paessler mentioning that there are limitations for WMI sensors. Other than that, we are okay with PRTG."
"They should work on syncing the solution with Gmail."
"Having a Unix implementation or Unix installation could be an improvement. Right now, it's based just on Windows, and that's a problem for some customers."
"When you email the support team, they take three to seven days to respond and resolve simple issues."
 

Pricing and Cost Advice

"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."
"This product could be cheaper."
"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 a little high."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."
"The price of PRTG is reasonable. PRTG's competitors like SolarWinds and ManageEngine charge more for the same functionality."
"The pricing is okay and it is cheaper than some competing products."
"We are licensed for 2500 endpoints."
"PRTG Network Monitor is cheap."
"The price of PRTG Network Monitor is reasonable."
"The ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
