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.

Transforms logs for real-time insights and seamless reporting
Logstash is used for transforming logs, and you can use many plugins in Logstash. Logstash works with configuration files that contain three main parts: an input part, a filter part, and an output part. In the input part, we can take logs from many sources such as Beats, files, or Kafka. The filter part is used to filter the logs that are shipped from Beats. From my understanding and experience with Logstash, it is usually used for processing logic, meaning I can control what fields should be transferred to Elastic and what fields shouldn't be transferred. This is the main function I use Logstash for. Elastic is a famous open-source searching engine that helps operation teams speed up the investigation process and provides real-time insights for performance reporting.

Quotes from Members

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

Pros

"We use this solution to examine disparate log sources and provide a cohesive method to search for anomalous behavior."
"We now have a central point of monitoring for all potential threats."
"Provides visibility into the network."
"We have made this the foundation of our security intelligence within our organization, and it has allowed us to detect and remediate Advanced Persistent Threats."
"Technical support is very helpful and responsive."
"In general, the visibility of events and advanced analysis of events are good."
"It's given us a ton of insight that we didn't have before."
"The calculated ROI around 90-100% for the first year because of our implementation and design of this solution allows me to cut my team in half."
"Everything aligns well with improving our organization."
"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."
"The functionality of Logstash is quite easy to implement and the plugin ecosystem of Logstash is great, with plugins for shell script monitoring and SQL monitoring working well with the tool."
"We have three or four Logstash servers for high availability."
"I can collect logs from various data sources, including hardware."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
 

Cons

"We have had some issues that have taken a long time to resolve, various technical issues that have taken longer to resolve than we desire."
"I don’t have a lot of confidence in their support. The support is not first class."
"NextGen SIEM has separate rules for AI, advanced intelligence, and MP rules - it would be better to have a centralized way to write the rules and create alarms."
"LogRhythm NextGen SIEM could improve by adding more applications for the banking sector. There are not any custom applications at this time."
"LogRhythm SIEM needs improvement in data grouping and manipulation capabilities."
"Right now there is the concern about being able to gather all of the data into the system."
"For our market, the solution is quite expensive. It would be ideal if they could work on and improve their existing pricing plans to help make it more affordable in our country."
"More help and assistance with some of the open source products, everything seems to be focused on Windows versus giving some guidance and some documentation on how to use it."
"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."
"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."
"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."
 

Pricing and Cost Advice

"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."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"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."
"NextGen SIEM's pricing is moderate."
