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."
"The sensors and probes are great, nice and lightweight, they don't take up too many resources on the system. We just deploy them out and they start reporting instantly."
"PRTG Network Monitor helps us quickly and easily discover a large number of sensors, so we can spend minimal time monitoring customer sites."
"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."
"PRTG gives us true visibility of the downtime of particular circuit functions, so if a circuit is up but not routing traffic, I will know with this tool and can write a customized script for a sensor to detect specific things."
"It is nice to have one place where all the information is right there in front of us."
"Stability-wise, I rate the solution a ten out of ten."
"PRTG Network Monitor is perhaps the most accurate tool we have used to monitor the capacity of the WAN connection."
 

Cons

"The pricing and AI can be improved."
"The remote probes seem to be a little bit buggy at times. They just stop working or they say they can't communicate. What we tend to do to is install the remote app onto the servers that we use. That seems to clear it up."
"There is not much not to love in this software but one item on my wishlist that has yet to be addressed in an intuitive way is the ability to use and manage templates."
"PRTG's documentation could be improved."
"The remote probes are okay. I think that there could be more sensors available, especially with newer technologies coming along."
"PRTG Network Monitor needs to show bandwidth utilization in proper graphs. It isn't easy to learn."
"Scalability is the only major sticking point for me. There is a recommended number of sensors, which is around 10,000 and we're double that... The only option we have to scale is to buy another core, which would be a separate, stand-alone instance..."
"I wouldn't mind better categories for the sensors."
"There is room for improvement in this solution for the performance and third-party monitoring protocols. They need to be updated to the latest ones."
 

Pricing and Cost Advice

"It's expensive."
"I rate the price of PRTG Network Monitor an eight on a scale of one to ten, where one is a high price, and ten is a low price."
"It's a cost-efficient tool."
"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."
"PRTG Network Monitor is very expensive."
"It's an annual license that is based on the number of endpoints that we're tracking and using."
"The pricing is okay and it is cheaper than some competing products."
"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."
"We pay for a perpetual license and we have a support fee."

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