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.

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

"Provides visibility into the network."
"LogRhythm SIEM offers advanced features such as AI engine modules, machine learning, and threat intelligence integration, which help reduce false positives. Advanced analytics streamlines incident response processes, enabling incident responders to prioritize and automate alerts."
"Currently, we are in the implementation phase. LogRhythm is better than QRadar from the point of view of collecting Windows events. It has a much higher view. You can enable monitoring by default."
"The log analysis feature is valuable."
"Their customer support is friendly and willing to help."
"The ability for me to go into the Web UI, and just learn what's going on in my environment."
"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."
"The initial setup is pretty easy."
"I can collect logs from various data sources, including hardware."
"We have three or four Logstash servers for high availability."
"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."
"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."
 

Cons

"We've had issues with scaling and local support."
"The console installation is an area with a shortcoming in the solution that needs improvement. If LogRhythm SIEM can offer a web console, it would be great."
"It's not easy for someone new to the solution."
"The customer support system is time-consuming."
"I would like it to do a lot of the automation (which I still need to learn more about), because I am essentially a one man shop doing all the jobs. I'd like for it to be able to do more for me."
"We're still struggling to get a real return on it and finding something that isn't false noise."
"Right now there is the concern about being able to gather all of the data into the system."
"The security playbook could be pre-defined and available to other analysts with similar security issues."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"We still have a problem with importing the log system."
"The product needs to improve its compatibility."
"Almost all the research can be very bad. We still have a problem with importing the log system."
 

Pricing and Cost Advice

"The license cost is around $10 per MPS."
"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."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"NextGen SIEM's pricing is moderate."
"The product is inexpensive than other tools."
"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."
"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."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
