Executive SummaryUpdated on Jul 13, 2025

Splunk Enterprise Security and Trellix ESM are leading solutions in the security information and event management (SIEM) space. Splunk holds the upper hand due to its advanced data integration capabilities and scalability, making it desirable for larger enterprises.

Features: Splunk excels in providing intuitive dashboards, extensive log monitoring, and robust data integration capabilities. Its ability to quickly extract and analyze data sets from various environments is appreciated. Trellix ESM offers effective log monitoring and customizable dashboards but lacks the extensive data handling seen in Splunk.

Room for Improvement: Splunk requires significant technical expertise to navigate its complexity, especially with customized queries and data handling. Cost is also a concern for smaller organizations. Trellix ESM needs to improve its integration capabilities, offering enhanced customization and a better user interface.

Ease of Deployment and Customer Service: Splunk provides versatile deployment options across public, private, and hybrid clouds but experiences mixed technical support reviews. Trellix ESM is deployed on-premises and hybrid cloud, valued for its straightforward deployment yet challenged by scalability in larger environments. Its customer service is generally responsive, with room for improved resource accessibility.

Pricing and ROI: Splunk is considered expensive, especially for smaller organizations, justified by robust features and flexibility, offering strong ROI through operational efficiencies. Trellix ESM is competitively priced, seen as cost-effective for small to medium enterprises, providing a balance between expense and capabilities, albeit its premium features suggest a higher price point.

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.

Room For Improvement

Users seek simplified setup, better integration, improved pricing, accessible training, automation, AI, and reduced false positives in Splunk.
Trellix ESM requires stability, HTML5 migration, and upgrades in customization, integration, support, usability, and AI for improved functionality.
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.

Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.

Valuable Features

Splunk Enterprise Security offers scalable log management, integrates easily, and provides advanced threat detection with customizable, user-friendly data analysis tools.
Trellix ESM excels in real-time threat detection, user-friendly interface, quick deployment, and strong integration with other technologies.
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.
For more quotes and insights, download the Splunk Enterprise Security report
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.

Featured Reviews

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.

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.
