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.

Customer Service

Sentiment score
5.4
LogRhythm SIEM's support excels in expertise and quick resolutions, earning high satisfaction despite occasional delays.
Sentiment score
6.2
Splunk Enterprise Security's support is knowledgeable but inconsistent, with response times varying; community resources are vital for effective solutions.
The technical support is good; we have a separate portal for partners, and since we are paying for the service, they provide a response timeframe based on severity—critical issues are addressed within four hours, medium issues within one day, and non-urgent issues may take a couple of days.
Cyber Security Engineer at Diyar United Company
Customer support is very helpful and effectively solves my problems.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
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

Principal Engineer at Aviatrix
 

Scalability Issues

Sentiment score
7.8
LogRhythm SIEM is highly scalable, easily expands across environments, and integrates well, suitable for medium to large enterprises.
Sentiment score
7.3
Splunk Enterprise Security offers scalable architecture, supporting diverse environments and data volumes, though costs increase with large data growth.
LogRhythm SIEM is highly scalable as it has modular components allowing me to expand storage, indexing, or other resources as needed.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
LogRhythm SIEM is scalable; it can handle about 200 or 500 devices without much difference.
Cyber Security Engineer at Diyar United Company
The scalability of LogRhythm SIEM is good enough, warranting an eight out of ten rating.
Security Engineer at Granicus Inc.
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
 

Stability Issues

Sentiment score
4.7
LogRhythm SIEM is stable with high uptime, strong support, handling large data, though updates may affect stability.
Sentiment score
7.5
Splunk Enterprise Security is highly reliable, with minimal stability issues, but requires careful resource management for optimal performance.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
LogRhythm SIEM still needs improvement regarding stability, particularly in environments with heavy data consumption.
Security Engineer at Granicus Inc.
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 a financial services firm with 10,001+ employees
 

Room For Improvement

LogRhythm SIEM needs improved integration, user interface, automation, scalability, documentation, and compatibility with non-mainstream platforms and Linux.
Splunk Enterprise Security needs UI improvements, better training, cost reductions, enhanced integrations, optimized analytics, and increased automation.
I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.
Cyber Security Engineer at Diyar United Company
There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments.
Security Engineer at Granicus Inc.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
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

LogRhythm SIEM is cost-effective for enterprises, offering transparent pricing and flexible licensing, yet incurs higher professional service fees.
Splunk Enterprise Security is costly, but its features justify the expense for those with larger budgets.
The license cost is around $10 per MPS.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.
Cyber Security Engineer at Diyar United Company
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

LogRhythm SIEM offers advanced threat detection, user-friendly interface, comprehensive log management, and automated alerts for enhanced security efficiency.
Splunk Enterprise Security excels in rapid data searching, real-time monitoring, flexible data ingestion, and comprehensive visualization for enhanced security.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
We have enough budget for cloud deployment, but we choose to keep it on-prem to ensure data privacy; cyberattacks are a concern, but data privacy is the foremost priority due to sensitive government information.
Cyber Security Engineer at Diyar United Company
This helps SOC analysts significantly as they can monitor all log sources through a dashboard, quickly identifying which sources haven't reported within their specified timeframes.
Security Engineer at Granicus Inc.
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.

Cyber Security Engineer at Diyar United Company
Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

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.
