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.

I have had nothing but good experiences with Splunk support, receiving timely and helpful replies.
Cyber Security Associate at SAP
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.
SOC Analyst at a computer software company with 1,001-5,000 employees
In general, they usually provide continuous support post-implementation, being in touch and trying to help, which makes their after-sale process better than Splunk.
CSO at Altera
 

Scalability Issues

Sentiment score
7.4
Splunk Enterprise Security offers excellent scalability, managing large data volumes and supporting effortless growth across industries.
Sentiment score
7.9
Sumo Logic Security offers scalable solutions for various environments, though some users express concerns about pricing.
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.
IT Security Engineer at a financial services firm with 201-500 employees
It is one of the things that separates it from other tooling, and if not, it is the most scalable solution out there.
Systems Development Engineer at a tech vendor with 10,001+ employees
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
CTO at a tech vendor with 10,001+ employees
The tool has high scalability because everything is based in the cloud.
Deputy Country Manager at PT Securite Asia Indonesia (ABP Securite)
I did not face any significant issues with Sumo Logic Security, but the pricing may be a concern as they try to upsell and raise the prices very quickly.
CSO at Altera
 

Stability Issues

Sentiment score
7.5
Splunk Enterprise Security is praised for stability and reliability, despite challenges with resource demands and custom configurations.
Sentiment score
8.0
Sumo Logic Security is highly stable with minimal issues, requiring optimized queries for performance, rating mostly seven to nine.
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.
Principal Engineer at Aviatrix
We need more SMEs, and there is no mechanism to tell us about indexer or search head issues.
Senior Manager at a financial services firm with 10,001+ employees
If there are many records, the system may stop or the UI may become unresponsive.

The query language is pretty straightforward and easy, and it is very powerful for building different searches and dashboards that will serve for later exploration of the same interests I have.
CSO at Altera
 

Room For Improvement

Splunk Enterprise Security needs UI improvements, better integration, richer documentation, competitive pricing, and enhanced AI and threat detection.
Sumo Logic Security needs improvement in dashboards, user experience, integration, threat insights, risk alerts, scalability, and pricing.
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Resident Consultant (Security Analyst) at helpag
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.
Security & Risk Analyst at a computer software company with 1,001-5,000 employees
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.
Security Consultant at Matiq
This can lead to alerts that are collections of disjointed signals that sometimes make no sense and lack real context; this simplistic approach makes it hard to find coherent stories during investigations.
CSO at Altera
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk.
SOC Analyst at a computer software company with 1,001-5,000 employees
This is crucial to sell to the government and financial sectors as they require data retention within each country.
Deputy Country Manager at PT Securite Asia Indonesia (ABP Securite)
 

Setup Cost

Splunk Enterprise Security offers robust insights but can be costly for high data volumes, challenging affordability for smaller businesses.
Sumo Logic Security pricing is reasonable for enterprises via AWS Marketplace, offering a balance of cost and functionality.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
CTO at a tech vendor with 10,001+ employees
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
System Engineer - Security Presales at Raya Integration
I find it to be affordable, which is why every industry uses it.
Vice President Research And Development at OSINT Ambition
This makes it more cost-effective because other solutions often include a third element in their pricing.
Deputy Country Manager at PT Securite Asia Indonesia (ABP Securite)
 

Valuable Features

Splunk Enterprise Security offers real-time threat detection, customization, and integration, enhancing security operations and data management capabilities.
Sumo Logic Security provides efficient log management, customization, and integration features, making it ideal for real-time monitoring and digital transformation.

Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues.

CSO at Altera
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.
SOC Analyst at a computer software company with 1,001-5,000 employees
Sumo Logic Security offers a single dashboard and customization, which are the most valuable features.

Featured Reviews

Senior Manager at a financial services firm with 10,001+ employees
Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.
SC
CSO at Altera
Has improved implementation speed and coverage but lacks contextual accuracy in alerts
One major improvement I would suggest for Sumo Logic Security is in its risk-based alerting system; while it initially sounds clever and modern, it works as a point-based system where an IP address or entity gets points for bad actions, raising alerts when enough points are collected. This can lead to alerts that are collections of disjointed signals that sometimes make no sense and lack real context; this simplistic approach makes it hard to find coherent stories during investigations. To improve in the support area, I recommend enhancing the technical part because, while the process is good, the actual quality may depend on the personnel involved.
