It is very stable.
 

Room For Improvement

IBM Security QRadar requires enhanced UI, integration, and AI, as it's complex, costly, and has suboptimal support and dashboard features.
LogRhythm SIEM needs better third-party integration, ease of use, performance enhancements, superior support, and improved scalability and cloud integration.
Splunk Enterprise Security needs user-friendliness, pricing adjustments, and improved integration to enhance functionality and user experience.
We receive logs from different types of devices and need a way to correlate them effectively.
If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules.
Improving the integration with IBM Server for MetaMask for correlation rules would be beneficial.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel.
Splunk Enterprise Security would benefit from a more robust rule engine to reduce false positives.
 

Setup Cost

IBM Security QRadar is a high-cost SIEM solution ideal for large enterprises, offering strong features and negotiable pricing.
LogRhythm SIEM offers competitive, transparent pricing with flexible licensing and premium enterprise features, justifying its higher cost.
Splunk Enterprise Security's pricing is complex and costly but justified by its advanced analytics and comprehensive features.
The license cost is around $10 per MPS.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
Splunk is priced higher than other solutions.
 

Valuable Features

IBM Security QRadar excels in scalability, integration, real-time threat detection, and supports diverse environments with customizable dashboards and analytics.
LogRhythm SIEM offers AI-driven threat detection, easy dashboards, compliance reporting, and scalable log integration for enhanced network security.
Splunk Enterprise Security excels with robust log management, seamless integration, real-time insights, and advanced threat detection for comprehensive monitoring.
Recently, I faced an incident, a cyber incident, and it was detected in real time.
IBM is seeking information about IBM QRadar because a part of QRadar, especially in the cloud, has been sold to Palo Alto.
The scenarios we could write regarding the compliance-related issues were quite helpful.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
This capability is useful for performance monitoring and issue identification.
They have approximately 50,000 predefined correlation rules.
The Splunk Enterprise Security's threat-hunting capabilities have been particularly useful in later releases.

Real-time incident detection and user-friendly dashboard benefit daily operations
There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement. So far, it seems very limited. It shows some good features in the correlation part, but I think there is room for improvement. For instance, when creating rules, it can suggest more rules, reducing the effort needed. If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules. Sometimes logs I receive don't mean anything, and I need technical stakeholders to share or forward logs, but these are sometimes inadequate. Keywords can help identify insufficient logs. I often lack time to verify logs. Sharing false positive results could be reduced to help my team.

User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Hello , As someone who worked with Splunk, Arcsight and Qradar. I am sorry but you cant compare between those two . IBM QRADAR works great with 100 eps and with 100000 eps. IBM Qradar analyze not only logs but Traffic, Policey's, Vulnerabilities, OSINT Data and integrates them all into a single quilty event which made the analysis factor and easter Risk management Risk assessment. Even in an SM...

Its is now an easy and clear answer. It depends on the environment, the integration needed, and the staff expertise. IBM is usually a better solution for large/very large installations and integration. But it requires much more staff and skills. But for smaller environments Splunk and LogRhytm is better. McAfee is correctly rated against others. So the answer is YES/AGREE for large installations. And NO/DISAGREE for smaller ones.

Hi, I disgree for SME installation since Q1 is usually on a large scale installation. While expertise on the product is still needed including integration with other security platforms. Splunk/LogRythm is good for Network correlation only not focusing much on the security area. McAfee is ok for both SME and Enterprise whilst expertise should also be considered as they have an easy and available tool for integration with their ticketing system, IPS, and AV. Hope this helps. Cheers, Lilet
