Comparison Buyer's Guide

Executive SummaryUpdated on Sep 18, 2024

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
1.0
Fortinet FortiSIEM delivers security improvements and customer satisfaction, leading to positive financial outcomes despite no explicit ROI measurement.
Sentiment score
3.2
In-house teams claim McAfee offers high ROI, but executives struggle to see it without C-level focused reports.
 

Customer Service

Sentiment score
7.4
Fortinet FortiSIEM's customer service is seen as professional but has mixed reviews on response times and support accessibility.
Sentiment score
4.3
Trellix ESM customer service is generally satisfactory, but technical support varies with noted delays and skill gaps.
There is a knowledgeable, though small, team of support engineers around the world.
Local tech support is available, however, for more critical or technical issues, we depend on the OEM directly, especially when it comes to on-prem solutions.
They take some time to respond because they need logs and investigations, which delays the response time.
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
7.2
Fortinet FortiSIEM scales well, accommodating different business sizes but faces challenges with licensing, architecture, and configuration complexities.
Sentiment score
8.6
Trellix ESM is highly scalable and adaptable, excelling in enterprise environments but may have limitations for medium enterprises.
Fortinet FortiSIEM is highly scalable.
At any point in time, when network devices increase or there is a change in the infrastructure, we can add more workers and collectors to expand our infrastructure setup.
Fortinet FortiSIEM 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.
 

Stability Issues

Sentiment score
5.6
Fortinet FortiSIEM is reliable and stable, handling updates well, with users rating its performance highly despite occasional bugs.
Sentiment score
8.3
Trellix ESM is generally stable with effective support, though some users experience bugs and interruptions affecting reliability.
It stabilizes itself in an appropriate time, so its uptime is good.
Some stability issues occur, but Fortinet's technical support team provides assistance.
These issues may cause unusual errors and user interface issues.
 

Room For Improvement

Fortinet FortiSIEM needs improvements in integration, user interface, support, cost, and features like AI and automated responses.
Trellix ESM requires stability, HTML5 migration, and upgrades in customization, integration, support, usability, and AI for improved functionality.
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management.
Enhancing the completeness of its APIs could aid in better external integrations.
Recently, they revised it to a subscription-based, all-inclusive license.
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

Fortinet FortiSIEM provides flexible pricing that can be cost-effective, but costs may increase with additional modules and scalability.
Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
Windows agent licenses cost around 3,000 Rupees per device per year.
Setting it up for oneself as an enterprise-licensed product can be quite expensive.
The revised model is subscription-based and more flexible.
 

Valuable Features

Fortinet FortiSIEM provides automation, analytics, and integration with a user-friendly interface for efficient threat detection and network monitoring.
Trellix ESM excels in real-time threat detection, user-friendly interface, quick deployment, and strong integration with other technologies.
It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security.
I find the real-time monitoring and correlation capabilities effective for security alerts.
In case of other ESM solutions, there are no parsers required, and almost every device is covered within the license, so there is no hidden cost as custom parsers.

Systems monitoring enhanced by firewall and intrusion detection features

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.
