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."
"We've managed to cut down on our P1 escalations by around about 70 percent."
"The product is easy to use and the web interface is fantastic."
"We have asked questions of their technical support and they have a very good response time."
"The alerting system is very stable, and it's helpful whenever any sensor is down."
"It will take care of all your monitoring needs, pretty much, but just be conscious of scale."
"PRTG Network Monitor is perhaps the most accurate tool we have used to monitor the capacity of the WAN connection."
"We can see trends for a lot of different things, such as hard drive space and bandwidth usage. We can see and plan for the future by knowing, "We're sort of at 75% capacity now. In three months time, we know we're going to be up to 90%,so we need to plan ahead for it, getting upgrades booked in place." Since things like this take time and effort, it's handy to see trends into the future of where our company is going."
"I can create my own program sensor. This means I can add extra monitoring capabilities into the already fundamentally strong foundation."
 

Cons

"The pricing and AI can be improved."
"They need to address the slowness issue that sometimes occurs with PRTG Network Monitor."
"Sometimes the error messages are too vague and don't directly tell me what went wrong."
"PRTG does not allow us to scan devices like we can scan software or another problem in it. Also, I cannot draw graphical graphs in Woodview/look. Another problem is that we cannot draw a good diagram in PRTG."
"Along with more room for automation, more room for advanced configuration can be integrated into the 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 database needs improvement."
"Once you start going above 5000 sensors, things do start to get a bit shaky. There are some best practice out there that you will need to adopt and be aware of."
"I would like the ability to monitor Cisco IRS devices."
 

Pricing and Cost Advice

"It's expensive."
"We used a product called SolarWinds in the past, and its cost was high. Whereas, PRTG came in at a third of SolarWind's cost."
"The pricing is comparable."
"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."
"We pay for a perpetual license and we have a support fee."
"The price of PRTG is reasonable. PRTG's competitors like SolarWinds and ManageEngine charge more for the same functionality."
"PRTG Network Monitor's price is a little high."
"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."
"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."

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