Has good network visibility
The primary use case is for monitoring and troubleshooting. We also use it for security.   The correlation of data in Apex helps to get full visibility of the entire enterprise. Apex is where we get the end-user experience score from one to ten. Network visibility is the most valuable feature.…

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

"Network visibility is the most valuable feature."
"PRTG Network Monitor has positively impacted my organization; before PRTG Network Monitor, it was very difficult to monitor a wide variety of sensors, but since implementing it, which supports numerous sensor types and protocols, it has become much easier for us to monitor servers, virtual systems, and cloud services to some extent."
"The solution has benefited our organization by showing us when devices are up and when you are down, and we can do an analysis on the availability of the resources."
"The pricing is reasonable so far; it's proven to be a good investment for our company."
"The feature set is brilliant; it does everything that we need it to do, and if it doesn't, then there is a nice forum that we can jump on."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"The product is easy to use and the web interface is fantastic."
"The support is fantastic."
"PRTG Network Monitor is user-friendly and takes just one click to install the solution in Windows."
 

Cons

"The pricing and AI can be improved."
"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."
"Dashboards can look cluttered on smaller screens, and the UI can feel crowded when there are hundreds of sensors in one group."
"From time to time, you need to reboot the PRTG probe server."
"The free version only gives us 100 free sensors to use. It would be nice if there was double that."
"The remote probes are okay. I think that there could be more sensors available, especially with newer technologies coming along."
"Although they are fairly comprehensive with what you can do with them, the mapping and dashboards are a bit clunky to set up."
"There are some vendor-specific sensors in PRTG Network Monitor, particularly for older hardware, that don't always provide consistent results."
"The traffic, the status of the devices can stand improvement."
 

Pricing and Cost Advice

"It's expensive."
"The price was pretty good, very competitive."
"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"It is expensive."
"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."
"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."
