Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

Has improved threat detection and reduced manual workload through real-time cloud insights
ThreatSync+ NDR has helped identify potential security gaps in my network, and we are currently working on resolving them. The impact on incident response time varies. During daytime operations, it reacts instantly with a notification delay of 10 to 20 minutes, while nighttime notifications can have up to eight hours delay. ThreatSync+ NDR has enhanced our ability to proactively manage network risks by enabling us to implement extra measures at a lower level based on its findings. The compliance reporting tools are comprehensive and meet our requirements. Though we haven't conducted official compliance reporting yet, we anticipate it will save approximately one day of work in report compilation. Regarding pricing, WatchGuard rates a nine out of ten. We maintain 1,001 licenses for ThreatSync+ NDR, serving approximately 1,000 users, with about 300 local users in the UK. ThreatSync+ NDR's effectiveness in identifying weaknesses before exploitation is excellent and very quick. I recommend ThreatSync+ NDR to other users based on its rapid deployment and immediate value delivery. I rate ThreatSync+ NDR 9 out of 10.

Quotes from Members

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

Pros

"We use it for monitoring whenever we update a new circuit or site."
"It is very rock solid, and we hardly have any hardware issues."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"Go with NETSCOUT."
"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."
"We are attracting customers in good sized numbers as we advertise and market this solution."
"The solution has helped to increase application and network uptime, reduced our mean time to repair significantly for application and network issues, and cut our overall troubleshooting time from an hour down to five minutes."
"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."
"ThreatSync NDR is a strong addition to our company's security architecture."
"Implementing ThreatSync+ NDR has influenced our business significantly as it provides enhanced security and saves several hours daily by eliminating manual log reviews."
 

Cons

"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"We don't use the single pane of glass view, even though we own it."
"It can be scalable. It just costs too much."
"The monitoring and reporting tool needs improvement."
"I'd like them to make the product more user-friendly."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"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."
"After using ThreatSync+ NDR for about a year, areas for improvement include the ability to pull logs from other vendors using an API."
 

Pricing and Cost Advice

"I would like it to be more scalable with less spend."
"The price is a little high."
"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"This product could be cheaper."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
