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.

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

"A lot of it is being a single point of log management for the whole company, not only for our compliance, but basically it has become an operational tool for our company, for our day-to-day stuff."
"LogRhythm's GUI is easy to explore, and we also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"The dashboards in the LogRhythm SIEM really help us as a starting point. It gives us a starting point we can go to every day. We walk through several dashboards to see anomalous activity for further investigation."
"For my situation, besides the investigation that LogRhythm offers, it's the AI Engine rule set that it offers, and it has brought us more significant changes in how we alarm and notify our users about what's going on in our network."
"Overall, versus competitors, it is a lot easier to use, a lot more user friendly, but it still gives you a lot of flexibility to do whatever you want."
"If I look back to my other SIEM solution providers, the one we had before this, it's light years difference."
"With LogRhythm, our SIEM solution offers more of a rounded perspective, especially from security, making sure they are not only operational, but they're operational in a security conscious manner."
"I don't feel like we just bought a product with LogRhythm, I felt that we bought a team."
"Everything aligns well with improving our organization."
"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."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"I can collect logs from various data sources, including hardware."
"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."
"We have three or four Logstash servers for high availability."
 

Cons

"Technical support could use a little work in the terms of responding back. The feedback that we received is they do need a little more staff."
"We would like to see a better base templates for reporting."
"The largest room for improvement would be inside the web platform, being able to have a longer log live time."
"The installation was a bit complex because we are running a virtual infrastructure."
"It seems with all of the advanced features that we haven't quite figured them out. It is very complex."
"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."
"Setting up LogRhythm SIEM is complex. Everything is complicated — the activity, integration, and analysis."
"Functionality, ease of use. There are a few gotchas in the applications."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"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."
 

Pricing and Cost Advice

"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"It is a very cost-effective solution."
"The license cost is around $10 per MPS."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."
"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."
"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."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
