7.4
Sumo Logic Security's support is responsive and helpful but can occasionally delay up to 48 hours; no phone support mentioned.
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.
The technical support for Splunk met my expectations.
They have a response time of forty-eight hours, which is not instant support.
 

Scalability Issues

Sentiment score
7.7
Splunk Enterprise Security is praised for scalability across environments, though on-prem expansion may face cost and planning challenges.
Sentiment score
8.1
Sumo Logic Security offers scalable, cloud-based solutions praised for integration, performance, and flexibility across diverse infrastructures, with positive user feedback.
It is easy to scale.
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
The tool has high scalability because everything is based in the cloud.
 

Stability Issues

Sentiment score
7.9
Splunk Enterprise Security is stable and reliable, handling large data efficiently, but requires careful capacity planning for complex queries.
Sentiment score
8.1
Sumo Logic Security is highly praised for stability, reliability, and maintaining performance under load, with minimal latency issues.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
If there are many records, the system may stop or the UI may become unresponsive.
 

Room For Improvement

Splunk Enterprise Security requires UI, integration, and documentation improvements; users seek better performance, visualizations, licensing, and automation features.
Sumo Logic Security faces challenges in performance, automation, support, API integration, and high costs, needing improvements across multiple areas.
Splunk Enterprise Security would benefit from a more robust rule engine to reduce false positives.
What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel.
Data retention can be better. If we want to look at the data for five months or six months, that is not available to us. We only have a history of 20 or 30 days.
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk.
This is crucial to sell to the government and financial sectors as they require data retention within each country.
 

Setup Cost

Splunk Enterprise Security provides robust features but is costly, especially for small organizations, with complex licensing and potential savings.
Sumo Logic Security users find AWS Marketplace simplifies billing and offers a competitive, cost-effective pricing structure despite scalability concerns.
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
Splunk is priced higher than other solutions.
This makes it more cost-effective because other solutions often include a third element in their pricing.
 

Valuable Features

Splunk Enterprise Security offers quick data search, integration, real-time alerts, and customizable dashboards for effective multi-cloud threat management.
Sumo Logic Security offers robust threat intelligence, real-time observability, and seamless integrations, making it essential for SecOps teams.
This capability is useful for performance monitoring and issue identification.
They have approximately 50,000 predefined correlation rules.
Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language.
Sumo Logic Security offers a single dashboard and customization, which are the most valuable features.
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.
WilsonAitan - PeerSpot reviewer
Offers a single dashboard with customizable features and a cost-effective pricing structure
Sumo Logic Security offers a single dashboard and customization, which are the most valuable features. Additionally, it has a cost-effective structure because it is based on data storage and the number of scans, rather than uploading data. This cost model impacts the customers positively by offering a more straightforward pricing structure.
