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.
Business Development Manager at Axians Germany
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.
IT Orchestration Architect at Penn State University
 

Customer Service

Sentiment score
6.0
IBM Security QRadar support quality varies, with inconsistent service; knowledgeable agents appreciated but response times and expertise are concerns.

6.2
Splunk Enterprise Security support is praised for its responsiveness but needs improvement in expertise and escalation speed.
Sentiment score
4.3
Trellix ESM customer service is generally satisfactory, but technical support varies with noted delays and skill gaps.
They assist with advanced issues, such as hardware or other problems, that are not part of standard operations.
Network and Security Architect at Deutsche Telekom
Support needs to understand the issue first, then escalate it to the engineering team.
Cyber Security Architects at VaporVM
The support is really good; for instance, if a critical ticket is submitted, you will get paged right away as it gets logged, and their analyst will look into it, letting you know as soon as possible so you can work on it.
Cyber Security Intern at a retailer with 1,001-5,000 employees
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.
Principal Engineer at Aviatrix
I would rate support for Trellix ESM 10 out of 10 because if we connect with the support in the UK, we get excellent support.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
It's rare for me to need them unless it's an issue with licensing, and they are the best in that regard.
Cyber Security Engineer at Protec
 

Scalability Issues

Sentiment score
7.3

Sentiment score
7.3
Splunk Enterprise Security scales well across environments, supporting large data volumes with flexibility, but can have cost considerations.
Sentiment score
8.6
Trellix ESM is highly scalable and adaptable, excelling in enterprise environments but may have limitations for medium enterprises.
For EPS license, if you increase or exceed the EPS license, you cannot receive events.
Cyber Security Architects at VaporVM
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
Scalability is quite easier with Trellix ESM, because all we need to do is add more receivers to it, so it can go to any point.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
 

Stability Issues

Sentiment score
7.5
IBM QRadar is seen as reliable, with stability dependent on proper configuration, version updates, and sufficient hardware resources.

I think QRadar is stable and currently satisfies my needs.
Architect of Cybersecurity at ASSIST - Software Services
The product has been stable so far.
Information Security Analyst at Banglalink
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
Splunk System Engineer at a non-tech company with 11-50 employees
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

IBM Security QRadar needs UI improvements, better integration, faster support, enhanced features, and competitive pricing to address user concerns.
Splunk Enterprise Security needs cost reduction, UI and integration improvements, enhanced AI, and better training resources for optimal functionality.
Trellix ESM requires stability, HTML5 migration, and upgrades in customization, integration, support, usability, and AI for improved functionality.
We receive logs from different types of devices and need a way to correlate them effectively.
Network and Security Architect at Deutsche Telekom
If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules.
Information Security Analyst at Banglalink
IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
Cyber Security Architects at VaporVM
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
If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
 

Setup Cost

IBM QRadar is costly but efficient, flexible in licensing, negotiable, and ideal for large enterprises over smaller ones.
Splunk Enterprise Security is costly but valued for advanced features, with pricing influenced by data ingestion volumes.
Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
Splunk is more expensive than IBM Security QRadar.
Cyber Security Architects at VaporVM
It was costly mainly because of the value you can get right now compared to other solutions.
CTO at Sabyk
It depends on how much you want to spend.
Strategic Account Executive at a computer software company with 51-200 employees
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
 

Valuable Features

Information Security Analyst at Banglalink
IBM Security QRadar gives the opportunity to improve the time to market of the releases with a great evaluation of cybersecurity breaches.
Strategic Account Executive at a computer software company with 51-200 employees
Compared to ArcSight, Splunk, or any other SIEM tools where you need their processing language such as structured query language, SPL, and in Sentinel there is KQL query languages, IBM Security QRadar doesn't require reliance on query languages.
SOC Engineer at a outsourcing company with 10,001+ employees
This capability is useful for performance monitoring and issue identification.
Staff Performance Engineer at ServiceNow
I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.
Splunk System Engineer at a non-tech company with 11-50 employees
Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues.
Specialist-Infrastructure Opertions at Allianz Technology
The weakest point is it doesn't cover almost all the devices, so the customer has to be more dependent on the parsers to be written by the Professional Services team.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.

HarshBhardiya - PeerSpot reviewer
SOC Engineer at a outsourcing company with 10,001+ employees
Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.
Sathis-Kumar - PeerSpot reviewer

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.

Offers comprehensive report generation while maintaining ease of integration
We need to improve Trellix ESM by making sure that most of the logging devices available in the global market should be covered, and if there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that. We can add some new features regarding AI in the future for Trellix ESM, but the maturity will take a longer time. There are many false positives that happen in an environment during the first couple of months, or around six months, so the system analyst is not able to identify whether the event which has occurred is a true positive or a false positive.

Hello , As someone who worked with Splunk, Arcsight and Qradar. I am sorry but you cant compare between those two . IBM QRADAR works great with 100 eps and with 100000 eps. IBM Qradar analyze not only logs but Traffic, Policey's, Vulnerabilities, OSINT Data and integrates them all into a single quilty event which made the analysis factor and easter Risk management Risk assessment.

Its is now an easy and clear answer. It depends on the environment, the integration needed, and the staff expertise. IBM is usually a better solution for large/very large installations and integration. But it requires much more staff and skills. But for smaller environments Splunk and LogRhytm is better. McAfee is correctly rated against others. So the answer is YES/AGREE for large installations. And NO/DISAGREE for smaller ones.

Hi, I disgree for SME installation since Q1 is usually on a large scale installation. While expertise on the product is still needed including integration with other security platforms. Splunk/LogRythm is good for Network correlation only not focusing much on the security area. McAfee is ok for both SME and Enterprise whilst expertise should also be considered as they have an easy and available tool for integration with their ticketing system, IPS, and AV. Hope this helps. Cheers, Lilet
