They assist with advanced issues, such as hardware or other problems, that are not part of standard operations.
The problem escalates through level one to level three, and then the process starts over with Novo again.
I received very good support, possibly due to a good relationship with IBM.
If you want to write your own correlation rules, it is very difficult to do, and you need Splunk's support to write new correlation rules for the SIEM tool.

I think QRadar is stable and currently satisfies my needs.
The product has been stable so far.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
 

Room For Improvement

Exabeam needs better flexibility, integration, clearer documentation, enhanced dashboards, faster support, improved UI, and reduced false positives.
IBM Security QRadar requires enhanced UI, integration, and AI, as it's complex, costly, and has suboptimal support and dashboard features.
Splunk Enterprise Security needs improved setup, GUI, user control, pricing, machine learning, and intuitive dashboards for better accessibility.
Exabeam needs to improve its documentation and provide more customization for dashboards and case management.
I have explored the SaaS version; it offers many new features.
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.
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

Exabeam offers reasonable pricing with flexible models, though not the cheapest, it's competitively priced compared to some competitors.
IBM Security QRadar is a high-cost SIEM solution ideal for large enterprises, offering strong features and negotiable pricing.
Splunk Enterprise Security is costly but valued for features and scalability, offering significant ROI with careful data management.
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

Exabeam excels with advanced analytics, intuitive interface, seamless integration, automation, and machine learning for enhanced security and ease of use.
IBM Security QRadar excels in scalability, integration, real-time threat detection, and supports diverse environments with customizable dashboards and analytics.

The product offers useful features like the dashboard, timeline, and session views, which enhance our security tools.
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.
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.

Featured Reviews

Stephen-Armstrong - PeerSpot reviewer
The SIEM provides a user-friendly UI experience
When events come into the system, the dashboard categorizes them by the highest risk score, not when they appear on the system. When you've got multiple ongoing incidents you can only see the highest risk score at the top of the list rather than the most recent detection. Exabeam's reporting dashboard could have included a filtering option to filter by the most recent detection.
Md. Shahriar Hussain - PeerSpot reviewer
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.
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.
