Jeroen-Dubbelman - PeerSpot reviewer
Director at Bitrate
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.
RickyMakkar - PeerSpot reviewer
Senior Network Security Consultant at NTT DATA
Unified monitoring has improved hybrid visibility and automates threat detection across our network
There are definitely areas for improvements in ThreatSync NDR, as no product is perfect. Its effectiveness depends on proper network visibility, so if important traffic segments are not mirrored or monitored, detection may be incomplete. Regarding improvements needed, ThreatSync NDR can definitely work on the user interface because it is currently a bit complex, and security teams sometimes find it unfamiliar with the behavioral analytics. If they can make it more user-friendly, that would help. Regarding ThreatSync NDR's AI capabilities, I think its governance and security are not fully enabled. While AI-assisted threat detections are there, it still requires significant improvements. However, the positive aspect is that it has significantly reduced the manual tasks and work of the security personnel.

Pros

"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."
"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."
"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."
"Go take a look at it. It's a great product and has great capabilities."
"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'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."
"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"
"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."
"Implementing ThreatSync+ NDR has influenced our business significantly as it provides enhanced security and saves several hours daily by eliminating manual log reviews."
"ThreatSync NDR is a strong addition to our company's security architecture."
 

Cons

"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."
"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."
"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."
"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."
"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."
"After using ThreatSync+ NDR for about a year, areas for improvement include the ability to pull logs from other vendors using an API."
"There are definitely areas for improvements in ThreatSync NDR, as no product is perfect. Its effectiveness depends on proper network visibility, so if important traffic segments are not mirrored or monitored, detection may be incomplete."
 

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."
