Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

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

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."

"I have no regrets using this product, I am very satisfied for what I paid for it and for the things I am able to do with the product."

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

"Enables us to go back in time to capture an issue and analyze it for a solution, and this after the fact analysis is key to overcoming the bump in the night issues."

"If you have the opportunity, I would strongly encourage you to get it, because it makes the IT experience easier and more flexible, by providing the ability to see things in your networks like the directory packet label."

"There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies."

"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."

More Observer GigaStor pros

"The most valuable feature of this solution is being able to see things graphically."

"The solution provides us response times to issues."

"Speed of deployment is one of the most valuable features."

"We can see which fiber links have been used heavily and, if they are used heavily, we can introduce more links to particular buildings or particular areas."

"It is very easy to set up, SNMP is very easy to set up on Windows and Linux, and you have a lot of options within PRTG, and I have not found something that I have not been able to monitor or that I have not been able to find data for."

"The support is fantastic."

"The most valuable features of PRTG Network Monitor are user-friendly, and the graphical interface is good for all the network devices that are mapped in this organization. It's very easy to find reports for any devices that we are looking for."

"The feature set is very strong compared to other products that I have used; it's great because it does everything that we need it to do, it's easy to use, and it looks great when you present it in an open office environment."

More PRTG Network Monitor pros

Cons

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."

"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."

"The Observer Console UI is consistent and stable, but could use some updating to be more modern."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"PRTG Network Monitor needs to enhance network performance monitoring. Moving towards observability, similar to what Datadog offers, could be beneficial."

"Users need to buy the more expensive licenses if they expect to be able to scale."

"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected. For example, the IAS sensor doesn't give immediate information, and the information you get from it isn't of good value. The web GUI of PRTG Network Monitor also needs improvement because errors keep popping up if it's not been updated to the latest version. What I'd like to see in the next release of the tool is end-to-end topology mapping for the business model, and that should be required. There has to be a technical map. Technical mapping and topological creation are missing in PRTG Network Monitor, so I would like to see those in the future."

"Sometimes, our PRTG Network Monitor system crashes and a lot of sensors go down."

"I'd like to see the inventory of the device improved."

"The user interface could be more modern as it is quite dated. PRTG Network Monitor can sometimes be too detailed and cluttered at the beginning, making it heavy to use."

"Limiting the bandwidth per host would be very good; however, that's beyond the capability of the PRTG."

"The traffic, the status of the devices can stand improvement."

More PRTG Network Monitor cons

Pricing and Cost Advice

"It's quite expensive."

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."

"The price is pretty comparable."

"The pricing is comparable."

"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."

"Our licensing costs are 10,000 euros over three years."

"We looked at PRTG and SolarWinds. From a cost side perspective, compared to PRTG, and from what you get back from it, PRTG was sort of a hands down the winner."

"When you have a lot of devices, PRTG Network Monitor can be costly."

"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."

"We pay for a perpetual license and we have a support fee."
