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.

Additionally, it facilitates in-depth analysis of application dependencies."

"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."

"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"

"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..."
