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

"Flowmon is more easy to understand and helps find network issues more quickly."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"The solution is stable."
"Flowmon is more easy to understand and helps find network issues more quickly."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"The most valuable features of PRTG Network Monitor are the threshold notification when certain traffic increases and goes beyond the defined threshold. The up and down status email notifications and other notifications are useful. Additionally, it is user-friendly, and customizable, and there are many features available."
"It is user-friendly. It is easy to set up health checks within PRTG and use scans. It is like a self-service tool, and anyone can configure their own settings within PRTG."
"The most advantageous aspect of PRTG Network Monitor is that you can start quite fast because there are many sensors you can use, and it's ready to use."
"The technical support seems to be quick, clever, and has a comprehensive knowledge base online, which is fantastic."
"What I've found most valuable is the custom sensor, which allows you to write scripts or code to monitor a specific metric in your environment."
"I found PRTG Network Monitor very useful for troubleshooting and monitoring the utilization of either the network or server."
"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."
"The fact that I can use custom MIB files to customize my sensors for the things that are not there as a default is a good feature."
 

Cons

"I do not know the detailed pricing."
"The licensing price could be better."
"If there was better visualization in Flowmon Solution it would be good."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"Performance-wise, PRTG Network Monitor still needs improvement because a large number of SNMPv3 queries reduces tool performance."
"PRTG's application monitoring sensor is not strong."
"The technical support from PRTG needs significant improvement."
"In a very few cases, customers want more detailed reports, which we cannot meet."
"The reporting features look very technical and that can be improved."
"In terms of sensors and probes, it would be really cool if PRTG had a purely Azure-based solution. We had to install a probe on one of our cloud servers and then let that probe out from there. It would be really cool if it just monitored Azure without having to install something on the device."
"PRTG Network Monitor should provide syslog monitoring since it is not available at this time."
"This product can be improved by updating the net flow interface. The one that is in place works – I can get all the information I need from it – but it is a little bit clunky."
 

Pricing and Cost Advice

"The price of the solution could be better."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The licensing fee accrues only once, but that of support is annual."
"The price of PRTG Network Monitor is reasonable."
"I rate the licensing for PRTG Network Monitor an eight out of ten."
"Licenses are very expensive, so I would like to see cheaper licensing."
"We pay for a perpetual license and we have a support fee."
"The pricing is reasonable for the features provided."
"We have an unlimited license for this solution."
"The ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable."
"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
