The technical support for Splunk met my expectations.
They have a response time of forty-eight hours, which is not instant support.

Splunk Enterprise Security is stable and reliable, but proper setup and careful capacity planning are crucial for optimal performance.
Sentiment score
8.1
Sumo Logic Security is stable and efficient, experiencing minimal issues, with stability ratings from seven to nine out of ten.

Room For Improvement

Splunk Enterprise Security needs better setup, integration, documentation, interfaces, access controls, data management, and pricing flexibility for improved user experience.
Sumo Logic Security needs better dashboards, pricing, automation, scalability, log handling, correlation, mapping, and faster support response.
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.
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk.
 

Setup Cost

Splunk Enterprise Security's cost is seen as high, prompting calls for flexible pricing to suit different budgets and needs.
Sumo Logic offers competitive pricing on AWS Marketplace, valued for simplicity and functionality but costly for smaller organizations.
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

Splunk Enterprise Security offers robust data analysis, real-time alerts, and machine learning, enhancing threat detection and incident response.
Sumo Logic Security provides customizable alerts, real-time observability, and seamless integrations for comprehensive, scalable security monitoring and forensics.
The Splunk Enterprise Security's threat-hunting capabilities have been particularly useful in later releases.
They have approximately 50,000 predefined correlation rules.
If we cannot find the data in other tools, like email security or NDR, we can fetch those logs in the Log Analytics platform of Sumo Logic.

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.
Vinay Patel D N - PeerSpot reviewer
Effective with good log analytics but needs better rule correlation
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk. Sometimes logs will not fetch, and there are issues if the log volume exceeds a threshold. Not every tool is integrated with Sumo Logic. The response time for their support could be better, and it is not very user-friendly.
