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.

Flexible device polling times and extensible modules are key features for me
There are lots of reasons why I'm using it. The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration. It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools. It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on.

Quotes from Members

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

Pros

"We were sold on the product based on the fairly narrow use cases that the sales reps gave us, and what we're seeing during our usage is that we can get there, and we're very excited about the potential."
"NetMon's best feature is traffic analysis."
"The initial setup is straightforward because we can deploy an open server."
"It has a very strong artificial intelligence engine."
"Compared to many other products in the market, I think LogRhythm has the highest cost to performance ratio in terms of its value."
"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."
"But just having it there, it's incredibly smart, incredibly easy to use, and the breadth of information we get off it is really good for investigations for us."
"It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on."
"In my case, I prefer to only poll interfaces that have descriptions, and the ones that don't have descriptions, I don't really want to know about them. It does allow for all these bits and pieces and adjustments, and fine tuning to get it to a point where it works for my needs."
"The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration."
"It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools."
"I think it compares very well to all the solutions in what it offers, and also I think compared to some of them, it is much more reliable."
"The big thing is the event management engine, which is really, really nice to use, and it comes at a reasonable price, unlike some of the competitors like Netcool from IBM. Those kinds of tools are hugely expensive and they come as resource-heavy types of solutions. This obviously doesn't require as much hardware, but it does offer similar benefits where you can manage all the events."
 

Cons

"Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time."
"Our customers would always like to see additional features."
"Their technical support isn't so great."
"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."
"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."
"Sometimes it's hard to find the network devices' self-audit logs."
"The training for this product is not very good and needs to be improved."
"One thing that surprised me was the current version of LogRhythm does not natively support Windows 2016."
"These kinds of solutions are more node- or device-based solutions. It would be nice in the future if they could be more data-oriented, so it would be easier for me to pull different stats based on ad-hoc requirements; but in a big, centralized database where I can pull specific things, and mix and match the way I want to."
 

Pricing and Cost Advice

"NetMon's licensing costs about $85k per year, with some extra costs for support."
"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."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."
"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."
