Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
AshishDubey - PeerSpot reviewer
A stable and scalable tool useful for network behavior analysis, DPA, and network forensic services
I have not worked much on LogRhythm NetMon to be able to comment on what needs improvement in the product since there is another team in our company that is working on the solution presently. LogRhythm NetMon's pricing model is an area of concern that should be made a little bit cheaper in comparison to the other players in the market currently. With players like IBM QRadar that propose QNI or Darktrace in the market, LogRhythm NetMon needs to consider a reduction in its pricing model.

Quotes from Members

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

Pros

"I can monitor a software made in-house to software of bigger companies."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"We love Nagios XI due to the fact that JPS Web is very useful."
"Nagios XI is stable."
"It has a very strong artificial intelligence engine."
"The protocols with which you see the traffic for a particular website that a client has in their environment, for example, are valuable. We can monitor whether the traffic is up to the mark or whether they need to add more bandwidth. Also, we can see if we're able to get real-time environment data as well. The customization dashboard is really good. LogRhythm NetMon has its own in-built dashboards which are helpful in guiding customization."
"LogRhythm NetMon's most impressive feature is that it's a bundled package, so you're not just relying on monthly data; you get a six-month view for more comprehensive indicators of compromise. This dual approach is precious. We implement LogRhythm NetMon in our cybersecurity strategy mainly for compliance and correlation of network, user, and decision activities, particularly for network firewalls and access control."
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
"NetMon's best feature is traffic analysis."
"Visibility is a valuable feature, the ability to see even if the traffic is not going into the firewall"
"The initial setup is straightforward because we can deploy an open server."
"It is a stable solution...It is a scalable solution."
 

Cons

"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The tool's AI model needs to be fixed."
"The GUI could be improved."
"The product's stability could be even better."
"The user interface needs improvement."
"Open-source software is usually not user-friendly."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
"The main concern is that LogRhythm has not improved NetMon but instead introduced a separate product, which many customers, including us, would prefer to be integrated into a single platform for easier management."
"Some of the automated tasks we can perform on QRadar cannot be performed on LogRhythm because the solution has limitations."
"Sometimes it's hard to find the network devices' self-audit logs."
"LogRhythm NetMon's pricing model is an area of concern that should be made a little bit cheaper in comparison to the other players in the market currently."
"There is an issue with tunneling in relation to how the connectivity is established between the end devices and where NetMon is installed. On the console, I often observe that there's a difference of a few seconds or maybe a minute, and this lag time should not be there."
"The training for this product is not very good and needs to be improved."
"Could use a topology diagram which would help get an exact visual."
 

Pricing and Cost Advice

"As it is not an agentless tool, I think it is expensive."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is an expensive solution."
"The pricing is high with separate licensing for the product and support."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"The product is expensive for smaller companies."
"I don't have visibility into the pricing of LogRhythm NetMon as it's handled through our commercial partnerships."
"Pricing is okay. There were some competitors that were extremely expensive and there were some which were really inexpensive but LogRhythm stayed in the middle of them."
"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."
"NetMon's licensing costs about $85k per year, with some extra costs for support."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
