ROI

Sentiment score

Splunk Enterprise Security boosts ROI with improved efficiency, error handling, and automation, reducing costs and streamlining operations.
Sentiment score
5.6
Wazuh provides significant ROI with fast detection and response times, cost savings, and benefits for SMBs and MSPs.
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.
We are able to secure the environment from all security threats and maintain an environment that is free from threats and attacks, especially cyberattacks.
I have seen value in security cost savings with Wazuh, as using proprietary EDR versions could save us substantial money.
 

Customer Service

Sentiment score
6.7
Splunk Enterprise Security receives high praise for support quality, though response times may vary; documentation and community are beneficial.
Sentiment score
6.0
Wazuh support receives mixed reviews; commercial support excels but free users face delays and time zone challenges.
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.
They responded quickly, which was crucial as I was on a time constraint.
We use the open-source version of Wazuh, which does not provide paid support.
The documentation is good and provides clear instructions, though it's targeted at those with technical backgrounds.
 

Scalability Issues

Sentiment score
7.7
Splunk Enterprise Security is scalable, integrates well, handles large data efficiently, but may incur costs, especially for on-premises setups.
Sentiment score
7.5
Wazuh is scalable, ideal for SMBs and enterprises, but requires technical knowledge and resources for complex 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.
It can accommodate thousands of endpoints on one instance, and multiple instances can run for different clients.
Currently, I don't see any limitations in terms of scalability as Wazuh can still connect many endpoints.
Scalability depends on the configuration and the infrastructure resources like compute and memory we allocate.
 

Stability Issues

Sentiment score
7.9
Splunk Enterprise Security is praised for its stability, reliability, and scalability, with large enterprises highlighting its exceptional performance.
Sentiment score
6.6
Wazuh offers stable performance with proper maintenance, yet frequent updates and configuration challenges can cause occasional issues.
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.
It is very stable.
The stability of Wazuh is strong, with no issues stemming from the solution itself.
The stability of Wazuh is largely dependent on maintenance.
The indexer frequently times out, requiring system restarts.
 

Room For Improvement

Splunk Enterprise Security needs cost-effective improvements in analytics, user interface, integrations, threat detection, and overall performance for better user experience.
Wazuh needs enhancements in UI, scalability, and integration, with focus on AI, log analysis, and efficient user management.
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 integration modules are insufficiently developed, necessitating the creation of custom integration solutions using tools like Logstash and PubSub.
I think Wazuh should improve by introducing AI functionalities, as it would be beneficial to see AI incorporated in the threat hunting and detection functionalities.
Wazuh could improve by creating videos on YouTube covering installation, use cases, and integration of third-party APIs for different scenarios that other SAAS services provide.
 

Setup Cost

Splunk Enterprise Security's high pricing is seen as prohibitive, especially for small businesses, requiring careful cost-benefit evaluation.
Wazuh is a cost-effective, open-source security solution with optional support, but consider additional infrastructure and third-party service 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.
Splunk is priced higher than other solutions.
Wazuh is completely free of charge.
Totaling around two lakh Indian rupees per month.
Wazuh is free to use, but there are licensing fees for third parties.
 

Valuable Features

Splunk Enterprise Security excels in search, data integration, real-time monitoring, and enhances threat detection and compliance management.
Wazuh offers robust security features, easy integration, and scalability, excelling in compliance and intrusion detection across environments.
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.
Wazuh is a SIEM tool that is highly customizable and versatile.
The system allows us to monitor endpoints effectively and collect security data that can be utilized across other platforms such as SOAR.
With this open source tool, organizations can establish their own customized setup.

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.
Sandip_Patel - PeerSpot reviewer
Evaluating robust file monitoring with insights for community support improvements
Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs. These aspects are vital as they provide alerts for changes and facilitate the monitoring of compliance. The platform is also relatively easy to set up and operate. Reports are straightforward to extract and prove useful for compliance requirements.
