Zabbix, free and open-source, reduces downtime and costs, improving network stability and significant enterprise savings.
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.
Customers see ROI as they save on staff and other resources.
 

Customer Service

Sentiment score
6.4
Splunk Enterprise Security support is knowledgeable but occasionally slow, with mixed efficiency reviews and valuable community resources.
Sentiment score
8.0
USM Anywhere's customer service is generally praised for responsiveness but experiences occasional delays and inconsistent support information.
Sentiment score
6.8
Zabbix users praise supportive documentation, community forums, and responsive technical support despite occasional time zone challenges and free version reliance.
We have paid for Splunk support, and we’re not on the free tier hoping for assistance; we are a significant customer and invest a lot in this service.
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.
It is so straightforward that I have never had to use the support.
 

Scalability Issues

Sentiment score
7.5
Splunk Enterprise Security offers scalable, flexible solutions handling large data volumes effortlessly, though cost concerns persist, especially on-premise.
Sentiment score
7.5
USM Anywhere is scalable for small to medium businesses, but enterprise-scale deployments face data volume and speed challenges.
Sentiment score
6.9
Zabbix is highly scalable, excels in diverse environments, but large deployments may require database optimization for efficient performance.
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.
USM Anywhere faces scalability issues because of a 60 TB limit.
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
Splunk Enterprise Security is stable and resilient, though resource-heavy queries can cause occasional bugs, needing optimized use cases.
Sentiment score
7.2
USM Anywhere receives mixed stability reviews, with some users praising its reliability and others reporting issues during updates or large data handling.
Sentiment score
7.5
Zabbix is reliable and resource-efficient, performing well with database tuning and handling heavy workloads without crashing.
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 users desire improved GUI, integration, pricing, training, data handling, and advanced features for better efficiency.
USM Anywhere needs improved performance, user interface, integration, and support, with better updates and less disruptive software changes.
Zabbix users seek improved UI, automation, integration, and customization with enhanced reporting, security, and scalability for non-technical users.
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.
There are scalability issues due to a 60 TB limit, which restricts its use for large customers like banks.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
 

Setup Cost

Splunk Enterprise Security is costly but valued for features and scalability, with pricing concerns for smaller businesses.
USM Anywhere offers scalable, affordable SIEM solutions ideal for SMBs, recommended for budget-conscious enterprises over costly competitors.
Zabbix is cost-effective and flexible, offering open-source monitoring with no licensing fees, low expenses, and optional support costs.
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.
I find it to be affordable, which is why every industry uses it.
The pricing is amazing and really cheap.
 

Valuable Features

Splunk Enterprise Security excels in log management, data ingestion, and integration, enhancing security operations with user-friendly features.
USM Anywhere offers event correlation, vulnerability scanning, and centralized logging with customizable, user-friendly security monitoring for small teams.
Zabbix is valued for open-source customization, scalability, comprehensive monitoring, alerting systems, and cost-effective enterprise IT 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.
The 365-day block query is a major feature.
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.
Zabbix is Linux-based open-source software, and the main use case is to reduce costs.

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.
