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.

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
6.5
Splunk Enterprise Security enhances visibility, improves error resolution, automates processes, and integrates well, though ROI assessment can be challenging.
Sentiment score
3.2
In-house teams claim McAfee offers high ROI, but executives struggle to see it without C-level focused reports.
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
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.

Splunk Enterprise Security support is knowledgeable but occasionally slow, with mixed efficiency reviews and valuable community resources.
Sentiment score
4.3
Trellix ESM customer service is generally satisfactory, but technical support varies with noted delays and skill gaps.
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.
I have had nothing but good experiences with Splunk support, receiving timely and helpful replies.
We've had great customer success managers who have helped us navigate scaling from 600 gigs to 30 terabytes.

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.
It's rare for me to need them unless it's an issue with licensing, and they are the best in that regard.

Scalability Issues

Sentiment score
7.4
Splunk Enterprise Security offers scalable, flexible solutions handling large data volumes effortlessly, though cost concerns persist, especially on-premise.
Sentiment score
8.6
Trellix ESM is highly scalable and adaptable, excelling in enterprise environments but may have limitations for medium enterprises.
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.
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.

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.

Trellix ESM is generally stable with effective support, though some users experience bugs and interruptions affecting reliability.

Room For Improvement

Splunk Enterprise Security users desire improved GUI, integration, pricing, training, data handling, and advanced features for better efficiency.
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.

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.

Valuable Features

Splunk Enterprise Security excels in log management, data ingestion, and integration, enhancing security operations with user-friendly features.
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

Kyle Vernham - PeerSpot reviewer
Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

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.
