Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Has supported real-time event detection and reporting accuracy while database integration has required extra effort
Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time. However, currently, it is not giving many challenges.It is difficult to integrate NetMon with other databases. We can customize NetMon's monitoring views, but it is done by the team who handles it, as it is outsourced.

Quotes from Members

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

Pros

"The technical support is good."
"We love Nagios XI due to the fact that JPS Web is very useful."
"An excellent solution that is easy and intuitive to implement."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"It is an open-source platform with valuable features for performance and stability."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"The solution's most valuable feature is its simplicity."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"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 analytics feature is the most valuable feature."
"It is a stable solution...It is a scalable solution."
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
"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."
"In general, this is a good product."
"It has a very strong artificial intelligence engine."
 

Cons

"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"The interface could be more user-friendly."
"I would like to see support for notification via SMS."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"LogRhythm's support team isn't responsive enough - it's common to wait a day or two for someone to deal with a case."
"Some of the automated tasks we can perform on QRadar cannot be performed on LogRhythm because the solution has limitations."
"The training for this product is not very good and needs to be improved."
"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."
"Sometimes it's hard to find the network devices' self-audit logs."
"Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time."
"Previously, it was typically every Monday that I was coming in - it would die over the weekend - and I would spend a day cleaning up databases."
"The platform's integration features often need to be improved."
 

Pricing and Cost Advice

"As it is not an agentless tool, I think it is expensive."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
"Nagios XI is open source."
"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 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 product is expensive for smaller companies."
"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."
"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."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
