Customer Service

Sentiment score
6.1
IBM Security QRadar's customer service is excellent but has inconsistent support quality and response times varying by region.
Sentiment score
6.7
Splunk Enterprise Security support is generally positive, but faster resolutions often require premium options due to occasional delays.
Sentiment score
6.9
Zabbix support is praised for responsiveness, community resources, and expertise, though documentation and non-paid support need improvement.
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 have sought assistance from Splunk Enterprise Security support in the past, particularly during deployment, and they provide friendly and effective help.
The technical support for Splunk met my expectations.
It is so straightforward that I have never had to use the support.
 

Scalability Issues

Sentiment score
7.5
IBM Security QRadar is renowned for its scalability, smoothly managing large loads with hardware integration and license upgrades.
Sentiment score
7.7
Splunk Enterprise Security excels in scalability with smooth integration but may incur cost issues due to volume-based pricing.
Sentiment score
6.9
Zabbix is praised for its scalability, distributed architecture, and efficiency, despite needing robust databases for larger deployments.
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.
I find it easy to scale Splunk Enterprise Security for our environment.
Zabbix is very scalable and lightweight.
Zabbix has high scalability.
I would rate its scalability ten out of ten.
 

Stability Issues

Sentiment score
7.6
IBM Security QRadar is stable with proper deployment, though some users face issues from misconfigurations or high log volumes.
Sentiment score
7.9
Splunk Enterprise Security is reliable, robust, and adaptable, effectively managing large data volumes with minimal downtime and ease.
Sentiment score
7.6
Zabbix is reliable and stable, with minimal issues; users value its low resource use and effective monitoring.
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.
Zabbix is very scalable and lightweight.
Zabbix is quite stable, and we haven't had any problems with Zabbix itself.
 

Room For Improvement

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 user-friendliness, pricing adjustments, and improved integration to enhance functionality and user experience.
Zabbix users seek UI improvements, better documentation, enhanced reporting, security, automation, integration, and modern workload adaptations.
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.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
 

Setup Cost

IBM Security QRadar is a high-cost SIEM solution ideal for large enterprises, offering strong features and negotiable pricing.
Splunk Enterprise Security's pricing is complex and costly but justified by its advanced analytics and comprehensive features.
Zabbix, a cost-effective open-source solution, offers free access without hidden fees, making it popular for enterprise adoption.
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.
Splunk Enterprise Security excels with robust log management, seamless integration, real-time insights, and advanced threat detection for comprehensive monitoring.
Zabbix provides open-source monitoring with customizable features, strong scalability, and robust support, ideal for cost-effective IT infrastructure management.
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.
If disk usage surpasses a threshold, say 70%, I receive alerts and can take proactive action.
Zabbix has a lot of features, including monitoring, status updates, and collecting information telemetry from storages and servers as well.

Featured Reviews

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.
ASM Naushad Alam - PeerSpot reviewer
Allows any number of customizations but lacks functionality for finding root causes
We have not yet purchased the commercial version so have a lack of technical ability. We do not yet fully know the key points or key features of the solution. We just use what we use along with WhatsUp Gold. Based on our use only, stability is rated a seven out of ten.
