Customer Service

Sentiment score
6.7
Splunk Enterprise Security support praised for knowledge and speed, but response times and complexity vary, premium options recommended.
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

OpenText Behavioral Signals faces scalability challenges, while technologies like ArcSight Intelligence excel, prompting consideration of alternatives like Splunk.
Sentiment score
7.7
Splunk Enterprise Security efficiently scales across environments, supporting large data volumes despite cost concerns, offering robust architecture.
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

OpenText Behavioral Signals is praised for its stability, receiving high ratings and fostering user trust through reliable performance.
Sentiment score
7.9
Splunk Enterprise Security is praised for stability and reliability, with minor bugs manageable under efficient configuration and resource management.
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.
 

Room For Improvement

OpenText and ArcSight require updates for usability, scalability, and pricing to compete with QRadar and Splunk effectively.
Splunk Enterprise Security needs improvements in rule engine, integration, cost-effectiveness, dashboard complexity, performance, customization, interface, and user training.
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

OpenText Behavioral Signals offers enterprise-priced licensing options with additional charges for new features not in the base license.
Splunk Enterprise Security's high costs deter smaller enterprises, yet its features often justify the expense for larger organizations.
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

OpenText Behavioral Signals synthesizes diverse logs, customizes environments, and enhances efficiency with a user-friendly, consolidated interface.
Splunk Enterprise Security offers fast data search, scalable log management, real-time alerts, and seamless third-party integration, enhancing threat detection.
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

Nagendra Nekkala - PeerSpot reviewer
A user-friendly solution that can be used to integrate the logs properly with different connectors
ArcSight Intelligence is easy to maintain; one person is enough for the solution's maintenance. The maintenance person will add new features or devices, make policy changes or configurations, and learn and guide other engineers about new threats. ArcSight Intelligence is a user-friendly solution, and users should buy it if their company can afford its cost. Overall, I rate ArcSight Intelligence a nine out of ten.
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.
