Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"It gives us insight into our entire installation, where we are multiple sites, going as far as the East Coast to the Central West Coast."
"NextGen SIEM's best feature is how it presents logs."
"We take in around 750 million logs a day. We have a lot of products and that would be a lot of different panes of glass that we would have to look through otherwise. By centralizing, we can triage and take steps much more quickly than if we tried to man that many interfaces that come with the products."
"When it comes to dealing with support, all my interactions have been great. Everyone has known what they're doing and have been quick to respond. They seem to always know the answer. I haven't stumped anybody yet."
"The user interface is pretty good compared to other SIEM tools."
"The most valuable features of the solution are network monitoring, user behavior analytics, and log collection."
"In general, the visibility of events and advanced analysis of events are good."
"LogRhythm's GUI is easy to explore. We also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"The product is scalable."
"A great feature of the solution involves its internal portal."
"The initial setup of Nagios Log Server was easy and straightforward."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
 

Cons

"We have run into problems with stability going through upgrade processes. Recently, we have been on the front edge of the upgrade path. When that happens we tend to run into issues either with certain functionality not working after the upgrades or stability issues because of the upgrades."
"I would like to suggest that they should improve their usage of third party tools for making dashboards and reports. If they would create their own tools for dashboard and report, it would be much better in terms of security purposes."
"The pricing is the only problem."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"The product's initial setup phase is pretty complex."
"One area for improvement in LogRhythm NextGen SIEM is that it's a Windows-based tool, and I feel it should be on the Linux operating system instead. Another area for improvement in the tool is the UI. There should be minor changes in the UI to make it better, though I like the dashboards in LogRhythm NextGen SIEM."
"The customer support system is time-consuming."
"I have probably submitted half a dozen log parser requests, and I keep finding more stuff that we need to keep an eye on that doesn't have a definition in LogRhythm."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The support could be better."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

Pricing and Cost Advice

"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"The license cost is around $10 per MPS."
"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"The pricing is very reasonable and accessible compared to other products in the market but I am not very sure about the exact licensing cost per year for our company."
"In the context of our country, the price of this solution is too high."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"For a single instance, the price is around $4,000."
"We found the pricing to be quite affordable."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
