Customer Service

Sentiment score
6.3
Exabeam's customer service garners mixed reviews, with varied responses on responsiveness, efficiency, and support quality across regions.
Sentiment score
6.1
IBM Security QRadar support is praised for expertise but criticized for slow response times and inconsistent service quality.
Sentiment score
6.6
Splunk Enterprise Security support is praised for its knowledge, but concerns exist about response times and initial contact expertise.
Even with TAM support from Exabeam, many issues go unresolved.
They assist with advanced issues, such as hardware or other problems, that are not part of standard operations.
Support needs to understand the issue first, then escalate it to the engineering team.
The problem escalates through level one to level three, and then the process starts over with Novo again.
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.
They try to close issues as soon as possible, often just offering documentation links.
They are responsive and effectively resolve issues.
 

Scalability Issues

Sentiment score
7.2
Exabeam scales well for enterprise use, despite some latency issues and slowdowns with increased filtering criteria.
Sentiment score
7.4
IBM Security QRadar is highly regarded for its scalability, with easy vertical and horizontal expansion and seamless cloud deployment.
Sentiment score
7.6
Splunk Enterprise Security excels in scalability; however, costs and infrastructure needs can impact on-premise and cloud deployments.
For EPS license, if you increase or exceed the EPS license, you cannot receive events.
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
It is easy to scale.
It's big in a Central European context, and small from a Splunk North American context.
 

Stability Issues

Sentiment score
7.2
Exabeam is stable with high ratings, though some users face processing delays and downtime affecting SOC monitoring.
Sentiment score
7.6
IBM Security QRadar is reliable but stability depends on correct deployment, capacity, and system resources, with minor update issues.
Sentiment score
7.8
Splunk Enterprise Security is stable and reliable, requiring careful capacity planning and monitoring for optimal performance.
These problems were not frequent, and the last six to eight months have been stable.
I think QRadar is stable and currently satisfies my needs.
The product has been stable so far.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
I would rate it a ten out of ten for stability.
 

Room For Improvement

Exabeam needs better flexibility, integration, clearer documentation, enhanced dashboards, faster support, improved UI, and reduced false positives.
IBM Security QRadar needs UI improvement, better integration, enhanced detection, streamlined operations, and customization for cost-effective functionality.
Splunk Enterprise Security requires better user guidance, intuitive tools, AI improvements, affordable pricing, and enhanced performance and integration.
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.
IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
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.
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.
 

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 costly but efficient, offering flexible pricing, EPS discounts, and potential cost savings with negotiation.
Splunk Enterprise Security can be costly due to data volumes, but offers extensive features and potential ROI for enterprises.
Splunk is more expensive than IBM Security QRadar.
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.

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.
We have FortiSOAR and IBM Resilient for IBM Security QRadar orchestration.
This capability is useful for performance monitoring and issue identification.
I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.
Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues.

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.
Mahmoud Younes - PeerSpot reviewer
Reliable installation and diverse use cases provide strong value
IBM Security QRadar has some areas for improvement. We have missed some DSM components. We need to customize logs where there is no DSM or connector for certain products. We can integrate but we have missed the DSM, which is the connector to pass logs coming from different applications. For example, with a university customer, we tried onboarding Canvas service. IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
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.
