Alerts have helped us catch critical network failures before they escalate
The first and foremost feature I appreciate about PRTG Network Monitor is that you implement it and forget it, requiring no maintenance. After deploying the core servers and using the auto-discovery feature, it had most of our network mapped out within an hour, making it very easy to set up and forget. With PRTG Network Monitor, I didn't need to spend weeks determining if a server was up or if a switch port was saturated, which means going from blind to having visibility in a single day is fantastic. The dashboards in PRTG Network Monitor are very good. The dashboard and UI are engaging, making it suitable not only for experienced users but also for beginners who are new to the tool. PRTG Network Monitor has positively impacted our organization by saving us a significant amount of money. During maintenance windows or patching, we used to receive false alerts, but since implementing PRTG, it has saved us thousands of dollars and has become a boon for us by providing convenience and being time and cost-saving. We have easily saved tens of thousands of dollars since using PRTG Network Monitor.

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

"I'd advise people not to waste one more moment and start using it immediately."
"PRTG Network Monitor helps us quickly and easily discover a large number of sensors, so we can spend minimal time monitoring customer sites."
"The authentication links into our standard Active Directory authentication, which is very good."
"The sensors and probes are great, nice and lightweight, they don't take up too many resources on the system. We just deploy them out and they start reporting instantly."
"The alerting system is very stable, and it's helpful whenever any sensor is down."
"Its initial setup process is fast and easy."
"You will not find anything cheaper that really does the job."
"The scalability is good. You can improve a remote host or the clustering. This gives it the flexibility to monitor another infrastructure remotely."
"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 technical support services could be better."
"I would like the ability to monitor Cisco IRS devices."
"If PRTG could help me see the bandwidth for each host I have on my network, either for a wireless or a wired network, that would be very helpful."
"Having a Unix implementation or Unix installation could be an improvement. Right now, it's based just on Windows, and that's a problem for some customers."
"I posed this question to PRTG and they were unresponsive, so it seems like not enough customers are complaining about it or would be potentially using it."
"In a very few cases, customers want more detailed reports, which we cannot meet."
"We need something that is more predictive. We would prefer if it wasn't a solution that was corrective and instead offered predictive insights so that we can handle problems before they even occur."
"It would be good if there were better graphical interfaces when you have it on multiple monitors."
"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

"PRTG Network Monitor is very expensive."
"We have an unlimited license for this solution."
"Sensors on free version can run out quick."
"We are licensed for 2500 endpoints."
"The pricing is comparable."
"The pricing is not too bad. It's not massively expensive, and the ability to upscale or even downscale licenses every year is brilliant for us."
"The licensing fees are billed annually and there are no costs in addition to this."
"We are satisfied with the price."
