Sentiment score
6.7
Splunk Enterprise Security offers knowledgeable support but encounters response delays, leading users to seek help from community forums.
It is ineffective in terms of responding to basic queries and addressing future requirements.

Sentiment score
7.7
Splunk Enterprise Security is praised for scalability across environments, though on-prem expansion may face cost and planning challenges.

They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
 

Stability Issues

Sentiment score
9.1
Cortex XSIAM is highly stable and reliable, with minimal downtime, swift issue resolution, and easy installation.
Sentiment score
7.9
Splunk Enterprise Security is stable and reliable, handling large data efficiently, but requires careful capacity planning for complex queries.
The product was easy to install and set up and worked right.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
 

Room For Improvement

Cortex XSIAM needs better integration, performance, developer-friendliness, and AI-enhanced security solutions despite satisfactory current features.
Splunk Enterprise Security requires UI, integration, and documentation improvements; users seek better performance, visualizations, licensing, and automation features.
In terms of incident response automation, it is quite poor due to the lack of integration with all security tools, making manual intervention necessary.
Cortex could improve the detection and online resolution of security vulnerabilities.
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.
Splunk could enhance its offerings by incorporating modules for network detection and response and fraud management.
 

Setup Cost

Cortex XSIAM pricing is competitive, considered reasonable yet costly with add-ons, offering value but varies on affordability.
Splunk Enterprise Security provides robust features but is costly, especially for small organizations, with complex licensing and potential savings.
The first impression is that XSIAM would be more expensive than others we tried.
The product is very expensive.
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

Cortex XSIAM provides advanced threat detection, integration, and user-friendly features, enhancing security management for Palo Alto users.
Splunk Enterprise Security offers quick data search, integration, real-time alerts, and customizable dashboards for effective multi-cloud threat management.
One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities.
The flexibility for creating manual workflows stands out.
Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language.

Featured Reviews

Forrest Stevens - PeerSpot reviewer
A robust security operation that ensures achieving automation, stability, and scalability
There is room for improvement in some areas, and I would highlight three key aspects. Firstly, the Attack Surface Management (ASM) module could benefit from more contextual depth. Currently, it tends to provide a broad overview without enriched context, and there's room for enhancement in this regard. Secondly, further integration capabilities with various other software products that can seamlessly tie into Cortex XSIAM would be advantageous. This would enhance its versatility and interoperability within a broader ecosystem. Regarding performance, there's potential for optimization. When multiple tabs are open in Cortex XSIAM, it can experience slowdowns, leading to longer load times for web pages. It's worth noting that this isn't a severe issue, and it doesn't entail waiting for extended periods, but there is room for improvement in terms of performance optimization.
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.
