We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
6.5
Splunk Enterprise Security enhances visibility, improves error resolution, automates processes, and integrates well, though ROI assessment can be challenging.
Sentiment score
7.6
Sumo Logic Security improves troubleshooting and operational efficiency, with users finding ROI generally justifies its continued use.
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
We couldn't calculate what would have been the cost if they had actually gotten compromised; however, they were in the process, so every investment was returned immediately.
On average, my SecOps team takes probably at least a quarter of the time, if not more, to remediate security incidents with Splunk Enterprise Security compared to our previous solution.
 

Customer Service

Sentiment score
6.4
Splunk Enterprise Security support is knowledgeable but occasionally slow, with mixed efficiency reviews and valuable community resources.
Sentiment score
7.4
Sumo Logic Security's support is responsive and helpful but can occasionally delay up to 48 hours; no phone support mentioned.
We have paid for Splunk support, and we’re not on the free tier hoping for assistance; we are a significant customer and invest a lot in this service.
I have had nothing but good experiences with Splunk support, receiving timely and helpful replies.
We've had great customer success managers who have helped us navigate scaling from 600 gigs to 30 terabytes.
They have a response time of forty-eight hours, which is not instant support.
 

Scalability Issues

Sentiment score
7.4
Splunk Enterprise Security offers scalable, flexible solutions handling large data volumes effortlessly, though cost concerns persist, especially on-premise.
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.
We currently rely on disaster recovery and backup recovery, which takes time to recover, during which you're basically blind, so I'm pushing my leadership team to switch over to a clustering environment for constant availability.
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.
The tool has high scalability because everything is based in the cloud.
 

Stability Issues

Sentiment score
7.6
Splunk Enterprise Security is stable and resilient, though resource-heavy queries can cause occasional bugs, needing optimized use cases.
Sentiment score
8.1
Sumo Logic Security is highly praised for stability, reliability, and maintaining performance under load, with minimal latency issues.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
Splunk has been very reliable and very consistent.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
If there are many records, the system may stop or the UI may become unresponsive.
 

Room For Improvement

Splunk Enterprise Security users desire improved GUI, integration, pricing, training, data handling, and advanced features for better efficiency.
Sumo Logic Security faces challenges in performance, automation, support, API integration, and high costs, needing improvements across multiple areas.
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.
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 is costly but valued for features and scalability, with pricing concerns for smaller businesses.
Sumo Logic Security users find AWS Marketplace simplifies billing and offers a competitive, cost-effective pricing structure despite scalability concerns.
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.
I find it to be affordable, which is why every industry uses it.
This makes it more cost-effective because other solutions often include a third element in their pricing.
 

Valuable Features

Splunk Enterprise Security excels in log management, data ingestion, and integration, enhancing security operations with user-friendly features.
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.
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.
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.
Sumo Logic Security offers a single dashboard and customization, which are the most valuable features.

Featured Reviews

Kyle Vernham - PeerSpot reviewer
Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

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.
