Comparison Buyer's Guide

Executive Summary

Review summaries and opinions

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

ROI

Sentiment score
8.0
LogRhythm SIEM boosts ROI, visibility, and security compliance, offering cost-effective risk management and productivity benefits, especially for medium enterprises.
Sentiment score
7.2
Splunk Enterprise Security enhances visibility, integration, and efficiency, streamlining operations and reducing costs, providing substantial returns for organizations.
Sentiment score
5.4
McAfee's ROI is praised for security management, despite executives seeking better ESM report visibility at the C-level.
I have noticed a return on investment with Splunk Enterprise Security, as it delivers substantial value for money.
Customers see the value in investing in this solution, particularly when it helps resolve issues quickly, turning a potential 20-hour response into one hour.
We are able to secure the environment from all security threats and maintain an environment that is free from threats and attacks, especially cyberattacks.
 

Customer Service

Sentiment score
6.9
LogRhythm SIEM's support is knowledgeable and responsive, though consistency and initial response times need improvement.
Sentiment score
6.7
Splunk Enterprise Security support is knowledgeable, but response times vary; experienced engineers and licensed users report better outcomes.
Sentiment score
5.9
Trellix ESM's customer service is praised, but technical support quality is inconsistent and varies by region, needing improvement.
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.
Customer support is very helpful and effectively solves my problems.
If you want to write your own correlation rules, it is very difficult to do, and you need Splunk's support to write new correlation rules for the SIEM tool.
They try to close issues as soon as possible, often just offering documentation links.
They are responsive and effectively resolve issues.
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.
 

Scalability Issues

Sentiment score
7.6
LogRhythm SIEM is praised for its strong scalability and effectiveness in accommodating expanding demands across diverse environments.
Sentiment score
7.7
Splunk Enterprise Security excels in scalability and flexibility for data, despite potential cost increases with larger usage.
Sentiment score
8.5
Trellix ESM is adaptable and scalable, suiting diverse business sizes and needs, though setup may challenge smaller users.
LogRhythm SIEM is highly scalable as it has modular components allowing me to expand storage, indexing, or other resources as needed.
LogRhythm SIEM is scalable; it can handle about 200 or 500 devices without much difference.
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.
It's big in a Central European context, and small from a Splunk North American context.
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.
 

Stability Issues

Sentiment score
4.4
LogRhythm SIEM is generally stable, reliable, and efficient, with some performance issues resolved through updates and proper resource allocation.
Sentiment score
7.9
Splunk Enterprise Security is praised for its stability and resilience, though occasional issues occur with complex queries or updates.
Sentiment score
8.5
Trellix ESM is perceived as stable overall, with occasional bugs resolvable by support, especially stable in data centers.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
 

Room For Improvement

LogRhythm SIEM needs better integration, UI improvements, enhanced reports, and Linux-based support for efficiency and tool integration.
Enhancements in UI, integration, support, and advanced features could improve Splunk Enterprise Security's usability, efficiency, and cost-effectiveness.
Trellix ESM needs improved stability, a modern interface, better integration, decreased resource use, and enhanced analytics capabilities.
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.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
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.
If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
 

Setup Cost

LogRhythm SIEM offers competitive pricing with comprehensive features, though scalability and additional features may increase costs.
Splunk Enterprise Security, despite high costs, is favored by large enterprises for its comprehensive features and robust capabilities.
Trellix ESM offers competitive and flexible pricing, with discounts for large purchases, easy deployment, and annual or monthly payments.
The license cost is around $10 per MPS.
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.
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.
Splunk is priced higher than other solutions.
 

Valuable Features

LogRhythm SIEM excels in threat detection, user-friendly interface, and integration, offering centralized logs and customizable alerts.
Splunk Enterprise Security enhances threat detection and incident response with advanced data analysis and integration from diverse sources.
Trellix ESM offers user-friendly features like dashboards, integration, threat monitoring, and automation for enhanced security and operational efficiency.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
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.
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.
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.

User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.
Daniel Durian - PeerSpot reviewer
Helps to monitor and detect cyberattacks
The tool's effectiveness depends on how you define your log sources. To build visibility of incoming and outgoing traffic, you need logs from perimeter defense, firewalls, web application firewalls, and endpoint protection. With good traffic visibility, incident response time is really quick. Trellix ESM provides situation awareness. On the dashboard, I can see outbound and inbound communications to known threat hosts, IPS/IDS activity, and threat intelligence of the perimeter defense in the firewall. This information helps preempt attacks.

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. Even in an SM...

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
