Executive SummaryUpdated on Aug 25, 2025

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
3.2
In-house teams claim McAfee offers high ROI, but executives struggle to see it without C-level focused reports.
Sentiment score
4.4
Wazuh offers significant ROI through reduced detection times and cost-effectiveness, benefiting small and medium businesses financially.
I have seen value in security cost savings with Wazuh, as using proprietary EDR versions could save us substantial money.
 

Customer Service

Sentiment score
4.3
Trellix ESM customer service is generally satisfactory, but technical support varies with noted delays and skill gaps.
Sentiment score
4.3
Wazuh support is effective for paid users, but open-source users face variability in community responsiveness and documentation use.
It's rare for me to need them unless it's an issue with licensing, and they are the best in that regard.
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.
They responded quickly, which was crucial as I was on a time constraint.
There is no dedicated technical support for Wazuh as it is open source.
The documentation is good and provides clear instructions, though it's targeted at those with technical backgrounds.
 

Scalability Issues

Sentiment score
8.6
Trellix ESM is highly scalable and adaptable, excelling in enterprise environments but may have limitations for medium enterprises.
Sentiment score
6.6
Wazuh offers adaptable scaling, effective for most, despite challenges, excelling in compliance and endpoint management with varied scalability scores.
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.
It can accommodate thousands of endpoints on one instance, and multiple instances can run for different clients.
Currently, I don't see any limitations in terms of scalability as Wazuh can still connect many endpoints.
Scalability depends on the configuration and the infrastructure resources like compute and memory we allocate.
 

Stability Issues

Sentiment score
8.3
Trellix ESM is generally stable with effective support, though some users experience bugs and interruptions affecting reliability.
Sentiment score
6.6
Wazuh's stability generally ranges from moderate to high, contingent on proper maintenance, updates, and user-specific technical environments.
The indexer frequently times out, requiring system restarts.
The stability of Wazuh is largely dependent on maintenance.
The stability of Wazuh is strong, with no issues stemming from the solution itself.
 

Room For Improvement

Trellix ESM requires stability, HTML5 migration, and upgrades in customization, integration, support, usability, and AI for improved functionality.
Wazuh requires enhanced interface usability, scalability, AI integration, and easier deployment, with improved reporting and native system integration.
If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
Machine learning is needed along with understanding user behavior and behavioral patterns.
The integration modules are insufficiently developed, necessitating the creation of custom integration solutions using tools like Logstash and PubSub.
I think Wazuh should improve by introducing AI functionalities, as it would be beneficial to see AI incorporated in the threat hunting and detection functionalities.
 

Setup Cost

Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
Wazuh is cost-effective for enterprises with open-source availability but incurs costs for infrastructure, support, and managed hosting.
Wazuh is completely free of charge.
I would definitely recommend Wazuh, especially considering Fortinet's licensing model which is confusing and overpriced in my opinion.
Wazuh is free to use, but there are licensing fees for third parties.
 

Valuable Features

Trellix ESM excels in real-time threat detection, user-friendly interface, quick deployment, and strong integration with other technologies.
Wazuh offers customizable open-source security solutions with SIEM, MITRE, and compliance tools for cloud-native, Kubernetes, and Azure environments.
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.
The fact that it is open source means it is always being expanded, which is beneficial for customizing solutions for individual client requests.
With this open source tool, organizations can establish their own customized setup.
The system allows us to monitor endpoints effectively and collect security data that can be utilized across other platforms such as SOAR.

Featured Reviews

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.
Ebenezer Okoh - PeerSpot reviewer
Innovative platform enables proactive threat hunting and endpoint monitoring
I have not seen Wazuh moving in the direction of AI-driven threat detection projects myself, but since the market is moving that way, I wouldn't be surprised if they implemented it soon. My plans to increase the usage of Wazuh or switch to another tool depend on what my boss decides. We don't refer to any community support specifically, as we rely on other platforms such as GitHub or Discord, depending on the application. I recommend that as more companies come on board with Wazuh, it will motivate those who contribute to it, but I am also cautious that as it gains attention, a large company might buy it and change its course of business. Overall, I rate Wazuh a nine out of ten.
