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.

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

"Nagios XI is stable."
"The most valuable feature is the monitoring of processes."
"I can monitor a phone on a desk to very big servers of any company."
"The solution has a lot of plugins and scripts integrated with it."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"Nagios XI is a simple monitoring tool with performance management."
"Nagios XI helped me to draw the network and check for system failures."
"The alerting system is very effective."
"The initial setup is straightforward because we can deploy an open server."
"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 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."
"NetMon's best feature is traffic analysis."
"The analytics feature is the most valuable feature."
"It is a stable solution...It is a scalable solution."
"It has a very strong artificial intelligence engine."
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
 

Cons

"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The product's stability could be even better."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"Open-source software is usually not user-friendly."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The product does not have SAP monitoring."
"The training for this product is not very good and needs to be improved."
"Some of the automated tasks we can perform on QRadar cannot be performed on LogRhythm because the solution has limitations."
"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."
"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."
"The platform's integration features often need to be improved."
"Sometimes it's hard to find the network devices' self-audit logs."
"Could use a topology diagram which would help get an exact visual."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
 

Pricing and Cost Advice

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is open source."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is an expensive solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"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."
"I don't have visibility into the pricing of LogRhythm NetMon as it's handled through our commercial partnerships."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
"The product is expensive for smaller companies."
"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."
"NetMon's licensing costs about $85k per year, with some extra costs for support."
"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."
