Sentiment score
7.7
Zabbix offers cost-effective, scalable monitoring with no fees, reducing downtime and commercial software expenses while increasing ROI.
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
I have noticed a return on investment with Splunk Enterprise Security, as it delivers substantial value for money.
Customers see the value in investing in this solution, particularly when it helps resolve issues quickly, turning a potential 20-hour response into one hour.
 

Customer Service

Sentiment score
6.7
Splunk Enterprise Security support is knowledgeable and generally effective, but response times and expertise levels could improve.
Sentiment score
6.9
Zabbix support is praised for responsiveness, community resources, and expertise, though documentation and non-paid support need improvement.
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.
It is so straightforward that I have never had to use the support.
 

Scalability Issues

Sentiment score
7.7
Splunk Enterprise Security offers versatile scalability, handling large data volumes effectively, with cost considerations for on-premises deployments.
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.
It's big in a Central European context, and small from a Splunk North American context.
Zabbix is very scalable and lightweight.
Zabbix has high scalability.
I would rate its scalability ten out of ten.
 

Stability Issues

Sentiment score
7.9
Splunk Enterprise Security is stable and reliable, though performance challenges occur with high data volumes and complex queries.
Sentiment score
7.6
Zabbix is reliable and stable, with minimal issues; users value its low resource use and effective monitoring.
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.
Zabbix is very scalable and lightweight.
Zabbix is quite stable, and we haven't had any problems with Zabbix itself.
 

Room For Improvement

Splunk Enterprise Security needs interface and integration improvements, streamlined setup, better training, cost adjustments, and enhanced AI features.
Zabbix users seek UI improvements, better documentation, enhanced reporting, security, automation, integration, and modern workload adaptations.
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.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
 

Setup Cost

Splunk Enterprise Security, seen as costly, offers extensive features, requiring careful data management to optimize expenses.
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

Splunk Enterprise Security offers powerful data management, flexible search, seamless integration, and advanced threat detection tools for efficiency.
Zabbix provides open-source monitoring with customizable features, strong scalability, and robust support, ideal for cost-effective IT infrastructure management.
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.
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

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.
