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…

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration
PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

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

Pros

"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."
"The most valuable features are speed and cost."
"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."
"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."
"We use it for monitoring whenever we update a new circuit or site."
"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."
"It's an easy product to set up."
"The most valuable feature is utilization."
"It is nice to have one place where all the information is right there in front of us."
"The real-time monitoring and alerting are its most valuable features."
"We have evaluated a lot of software and we found PRTG Network Monitor the best solution."
"We like the solution's report writing and the way that it compiles the system's information from around the network and brings it all back into the central site and the interface."
"The most valuable feature of this solution is being able to see things graphically."
"I can customize the port as per my need and the real-time monitoring feature that is already provided to me."
"Monitoring takes time, and anything that cuts down on time spent monitoring saves money."
"The most valuable aspect is the diverse range of features it offers."
 

Cons

"Sometimes, we can't access it."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"We don't use the single pane of glass view, even though we own it."
"The solution is not great, but it is not bad."
"The monitoring and reporting tool needs improvement."
"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."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"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."
"We need something that is more predictive. We would prefer if it wasn't a solution that was corrective and instead offered predictive insights so that we can handle problems before they even occur."
"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."
"Needs ability to monitor standard notification time (notify after X time)."
"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."
"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."
"To have the additional features costs a lot. It's too much."
"If PRTG Network Monitor could reconsider the pricing structure to make it more accessible to everyone, it would become a more stable product in the market for the future."
"PRTG can fix that, but it's only good for small workloads."
 

Pricing and Cost Advice

"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."
"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."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"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."
"I rate the licensing for PRTG Network Monitor an eight out of ten."
"The pricing is very low compared to other solutions."
"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."
"The price of PRTG Network Monitor is more expensive than other solutions, such as OP Network Manager."
"The price of PRTG is reasonable. PRTG's competitors like SolarWinds and ManageEngine charge more for the same functionality."
"PRTG Network Monitor is cheap."
"Pricing for PRTG Network Monitor is a nine out of ten. It meets my company's budget and monitoring requirements. My company is on a perpetual license."
