Utilizing data monitoring capabilities and scripting potential to optimize system management
I frequently program functions with PowerShell, and although Bash could be used, my specialization is in PowerShell. Two of us focus on programming in PowerShell for infrastructure optimization. I set up a dedicated server to run scripts every hour, generating files for Checkmk output. However, Checkmk does not allow running scripts at varying intervals. I am working on this in the raw version of Checkmk.

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 really like the auto-discovery feature."
"We can monitor multiple sites using the product."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"Checkmk helps me compare data and foresee issues."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"The most valuable feature of the solution is that it has a lot of different pieces, and they all work together...It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"The initial setup of Checkmk was easy...It is a very stable solution."
"Overall, from one to ten, I rate Checkmk a nine."
"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

"It is easy for tech-savvy people, but newcomers might find it intimidating."
"The initial setup is a bit complex."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."
"Checkmk does not allow running scripts at varying intervals."
"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."
"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."
"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."
"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

"The price of Checkmk is cheaper compared to other enterprise products."
"The product is affordable."
"Checkmk is a fairly reasonably priced solution."
