Featured Reviews

KeithGalleros - PeerSpot reviewer
A solution providing visibility into all data traversing your network but needs to be more cost-efficient
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. I'd also like to see LogRhythm NetMon improve in terms of cost efficiency, especially regarding adding new products that may overlap in functionality. Specifically, I would appreciate enhanced detection and response capabilities directly integrated into NetMon to avoid needing additional rules or tools from LogRhythm. Regarding integration capabilities, I think NetMon's current agent-based approach is limiting. Integrating with protocols like Gflow and Netflow would be better, allowing seamless integration with our existing network equipment. This would solve the problem of agent-based restrictions and improve overall integration.

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

"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 has a very strong artificial intelligence engine."
"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."
"The analytics feature is the most valuable feature."
"NetMon's best feature is traffic analysis."
"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."
More LogRhythm NetMon pros
"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."
"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."
"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."
"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."
 

Cons

"Some of the automated tasks we can perform on QRadar cannot be performed on LogRhythm because the solution has limitations."
"Could use a topology diagram which would help get an exact visual."
"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."
"The training for this product is not very good and needs to be improved."
"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."
"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."
More LogRhythm NetMon cons
"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

"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."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
"I don't have visibility into the pricing of LogRhythm NetMon as it's handled through our commercial partnerships."
"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."
