SumitKumar20 - PeerSpot reviewer
Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.
PRANIL CHANDARKAR - PeerSpot reviewer
Open-source accessibility and ease of implementation empower adaptable log management
As both a customer and an integrator, I think the best features in Logstash are that people prefer it because it is open to all, as it is an open-source version. The functionality of Logstash is quite easy to implement. I can say that the plugin ecosystem of Logstash is great. I have used some plugins for shell script monitoring and for SQL monitoring, and these are all working well with Logstash. The real-time processing capabilities of Logstash are also pretty fine with the tool. When I use the community edition, I have to do many things manually. If I am using enterprise Elastic, then that is taken care of by the Elastic native machine learning.

Quotes from Members

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

Pros

"The initial setup is pretty easy."
"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."
"SOAR is integrated with the dashboard that we use for threat management. Because it's all integrated, it is useful for us when we deploy something on-prem."
"The user interface is pretty good compared to other SIEM tools."
"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"As a SIEM, probably the best feature is that it can be tuned effectively. There are very few SIEMs out there that can be effectively tuned to provide you with meaningful information and not be overwhelmed."
"It has centralized monitoring for our security operations. Therefore, it improves our analysts' work."
"What I found most valuable in LogRhythm NextGen SIEM is that it's user-friendly. I also like its dashboard, which shows all the logs and information I want to see."
"We have three or four Logstash servers for high availability."
"Everything aligns well with improving our organization."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"The transformation means we ship the logs in the way that we want them to be presented in Kibana, which is the main function we use Logstash for."
"I can collect logs from various data sources, including hardware."
 

Cons

"My big thing is the easability. I don't like to go to two different systems. The fat client that you have to install to configure it, then the web console which is just for reporting and analysis. These features need to collapse, and it needs to be in a single solution. Going through the web solution in the future is the way to do it, because right now, it is a bit cumbersome."
"There used to be the ability to create alarms based on message text that was included in LR Version 6.x that has been removed in LogRhythm 7.x, and on that, I would like to see it added back."
"We had a little bit of difficulty implementing a disaster recovery situation because it was leveraging only Microsoft native DNS and it wouldn't work with our Infoblox DNS deployment that we use in our environment. They've been working on that behind the scenes."
"The integration is slightly difficult with other assets, like EDR technologies or firewalls."
"LogRhythm NextGen SIEM is currently based only on the Windows platform. This means that some of our customers have to purchase a Windows license elsewhere. If LogRhythm can move to a Linux platform or a proprietary platform, it would be very helpful."
"The initial setup is not so easy because it is quite a process."
"It is a product that is very hard to use."
"NextGen SIEM's integration with other software is good but could be improved."
"We still have a problem with importing the log system."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"Almost all the research can be very bad. We still have a problem with importing the log system."
"The product needs to improve its compatibility."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
 

Pricing and Cost Advice

"NextGen SIEM's pricing is moderate."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"In the context of our country, the price of this solution is too high."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"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."
