Cyber Security Engineer at Diyar United Company
The scalability of LogRhythm SIEM is good enough, warranting an eight out of ten rating.
Security Engineer at Granicus Inc.
We currently rely on disaster recovery and backup recovery, which takes time to recover, during which you're basically blind, so I'm pushing my leadership team to switch over to a clustering environment for constant availability.
IT Security Engineer at a financial services firm with 201-500 employees
It is one of the things that separates it from other tooling, and if not, it is the most scalable solution out there.
Systems Development Engineer at a tech vendor with 10,001+ employees
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.

Room For Improvement

IBM SevOne struggles with upgrade complexity, reporting detail, integration, visualization, and seeks enhanced analytics and cloud monitoring improvements.
LogRhythm SIEM needs improved integration, customization, performance, usability, better support, and enhanced documentation for optimal user experience.
Splunk Enterprise Security requires enhancements in visualizations, ease of use, AI integration, and improved documentation and training.
It would be beneficial to have out-of-the-box integration with third-party vendors and improvements in correlation features.
Network monitoring engineer at a tech vendor with 10,001+ employees
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.
Cyber Security Engineer at Diyar United Company
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.
Security Engineer at Granicus Inc.
If LogRhythm SIEM could make a lightweight version of their solution, that would be quite competitive because some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity.
Engineer Information Security at N-Able (Pvt) Ltd
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Resident Consultant (Security Analyst) at helpag
Splunk Enterprise Security is not something that automatically picks things; you have to set up use cases, update data models, and link the right use cases to the right data models for those detections to happen.
Security & Risk Analyst at a computer software company with 1,001-5,000 employees
For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.
Security Consultant at Matiq
 

Setup Cost

IBM SevOne NPM provides scalable, flexible licensing, though upfront costs can be high; negotiation is advised for cost management.
LogRhythm SIEM offers competitive, transparent pricing suitable for medium to large businesses, with high initial setup costs.
Splunk Enterprise Security is costly but valued for its extensive functionality, appealing mainly to larger enterprises with flexible licensing.
The license cost is around $10 per MPS.

Improves infrastructure planning by helping us analyze network traffic
We use SevOne to collect and report on network flows SevOne improves infrastructure planning by helping us analyze network traffic. We can look at bandwidth for specific endpoints on the customer's network and analyze traffic to identify issues. For example, maybe some connectors are unavailable.…

Cyber Security Engineer at Diyar United Company
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.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.
