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 needs better setup, integration, documentation, interfaces, access controls, data management, and pricing flexibility for improved user experience.
Cortex could improve the detection and online resolution of security vulnerabilities.
An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.
Splunk Enterprise Security would benefit from a more robust rule engine to reduce false positives.
 

Setup Cost

Cortex XSIAM pricing is competitive, considered reasonable yet costly with add-ons, offering value but varies on affordability.
Splunk Enterprise Security's cost is seen as high, prompting calls for flexible pricing to suit different budgets and needs.
The first impression is that XSIAM would be more expensive than others we tried.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
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 robust data analysis, real-time alerts, and machine learning, enhancing threat detection and incident response.
One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities.
The Splunk Enterprise Security's threat-hunting capabilities have been particularly useful in later releases.

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.
