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.

Proactive monitoring has reduced network downtime and enables rapid incident response

The main benefits PRTG Enterprise Monitor provides for us include helping us respond quickly to network problems. For our virtualization switches, we normally use a different vendor, but I am not in charge of that particular system. I have not really used the pre-configured sensors feature in PRTG. A different team handles reporting. For now, nothing really comes to mind regarding additional functions for PRTG. I think it is good for what we use it for. I cannot really say much about technical support because I have never had a situation where I have to reach out. I would give PRTG Enterprise Monitor a final rating of eight. I would definitely recommend PRTG Enterprise Monitor to other users. I am an end user of the product. I am quite satisfied with the alerting part of PRTG, as it is quite good.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

"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."

"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."

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

"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."

"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."

"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."

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

More Observer GigaStor pros

"The product is easy to use and you don't need to have any training. You can use it even if you don't have an IT background."

"The product is easy to understand."

"I would recommend PRTG Enterprise Monitor to others as it works well with Android devices, and you can try the free version before purchasing."

"It provides a vast array of options for dashboard creation and monitoring of the activities within the environment."

"The product's most valuable feature is network analysis."

"From a technical perspective, the product's most valuable feature is SNMP, an open standard monitoring protocol that works across various network devices and operating systems, including UNIX and Windows."

Cons

"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."

"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."

"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."

"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."

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

"As of this moment, the graphics might need some improvement, because a lot of the information there must be input first to have full potential."

More Observer GigaStor cons

"The licensing policy needs to change."

"PRTG Enterprise Monitor should include more functionalities and features that are similar to SolarWinds."

"In my opinion, one area that could be improved in PRTG Enterprise Monitor is the capability to send SMS notifications. Notifications are crucial for alerting us to areas that require attention."

"They should work on minimizing false positives by sending alerts promptly and confirming errors with minimal troubleshooting requirements."

"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."

"The solution could be improved by including a processing monitor, possibly with a language interface like Lua, allowing for writing custom sensors and processing outcomes of inputs."

"The licensing policy needs to change. The current model requires customers to purchase a minimum of two thousand licenses, which is not flexible for all customers."

"When it comes to dashboard customization in PRTG Enterprise Monitor, there are not too many options, and I think that would not be a strong point for PRTG, but for our use cases, we do not really need that kind of customization."

More PRTG Enterprise Monitor cons

Pricing and Cost Advice

"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."

"It's quite expensive."

"The solution is affordable."

"The pricing is $2,149 for software without maintenance, and licenses are sold in the minimum bundle of 500 interfaces."

"PRTG Enterprise Monitor is an expensive product."
