Before using SentinelOne Singularity AI SIEM, investigating a moderately complex alert took around thirty to sixty minutes because analysts had to collect logs from multiple security tools.

The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
DevOps&Cloud Engineer Mentee at CertDirectory.io
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.

Vice President Cyber Security Practice Head at orbit techsol w pvt.ltd
In rating the technical support for SentinelOne, it depends on whether we are discussing EDR or SentinelOne Singularity AI SIEM.
Managing Director at iMark Consult
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.
Senior System Administrator at a tech services company with 5,001-10,000 employees
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.

It is designed to handle growing log volumes and supports environments that include on-premises infrastructure, cloud services, endpoints, identity platforms, and network devices.
Desktop Support Engineer at a outsourcing company with 51-200 employees
With any AI adoption, the end goal should be more governance and data security and safety.
Associate Vice President at Novac Technology Solutions
The performance depends on the configuration.
IT Security Analyst at a tech consulting company with 11-50 employees
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
We have found no negative impact from scaling.
Soc Analyst at Softcell Technologies Global Pvt.Ltd

When it comes to stability, I would give SentinelOne Singularity AI SIEM a nine.
IT Security Consultant at Systemhaus for you GmbH
In terms of performance stability, I have never had any crashes, downtimes, or performance 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 Bank of America
 

Room For Improvement

SentinelOne Singularity AI SIEM requires improvements in performance, customization, integrations, automation, pricing, and clearer AI insights.
Splunk Enterprise Security needs UI, cost efficiency, AI integration, simpler onboarding, better support, and improved false positive management.
The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things.
Associate Vice President at Novac Technology Solutions
The interface flickers frequently, and sometimes it does not load properly.
IT Security Analyst at a tech consulting company with 11-50 employees
Whenever OT security comes into the picture, the customers do not allow us to integrate their OT devices on a cloud. It should be available on-premises because the OT SIEM market, in the India market for instance, is something around a four to eight billion dollar market.
Vice President Cyber Security Practice Head at orbit techsol w pvt.ltd
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
 

Setup Cost

SentinelOne Singularity AI SIEM offers a value-driven package with bundled services; its advanced capabilities justify slightly higher costs.
Splunk Enterprise Security is feature-rich but often expensive, favoring larger enterprises with strategic data management for cost efficiency.
I find SentinelOne's pricing to be reasonable and competitive.
Information Security Principal at a venture capital & private equity firm with 1,001-5,000 employees
Features such as centralized log management, AI-driven analytics, automated workflow, and integrated security options can reduce operational overhead and improve SOC efficiency, which helps justify the investment.
Desktop Support Engineer at a outsourcing company with 51-200 employees
Compared to another SIEM tool's pricing, the pricing is the best, from my side.
Technical Support Executive at Softcell Technologies Limited
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

SentinelOne Singularity AI SIEM enhances security with automation, AI analytics, third-party integration, and improved SOC efficiency.
Splunk Enterprise Security enhances threat detection and response with AI intelligence, customizable dashboards, and scalable architecture for improved security.

I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.

Featured Reviews

Dev Reshwal - PeerSpot reviewer
Technical Support Executive at Softcell Technologies Limited
Automation has reduced workload and real-time monitoring provides faster incident response
SentinelOne Singularity AI SIEM is the best, but sometimes the dashboards are a little simple compared to other tools. The custom dashboard is not available in their features. Therefore, I would suggest adding the custom dashboard for any of our requirements. The AI-driven analytics from SentinelOne Singularity AI SIEM has not affected our ability to reduce false positives. SentinelOne Singularity AI SIEM has affected my SOC's efficiency in investigating alerts and responding to incidents. If we receive any alerts, we can observe what activity is being done. We can see if it is malicious or something suspicious, or a true positive. We can analyze the path, the hash, and whether the signature is verified or not. We can see if it is an alert triggered by any engine. We can see the source of this. We will do that type of analysis and raise it to the client side. Also, if I identify anything suspicious or malicious in the alert, I will forcefully kill and quarantine it immediately.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
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.
