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
4.6
Cortex XSIAM enhances incident management and provides significant financial returns by automating detection and response, reducing staffing needs.
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
5.8
Cortex XSIAM support varies; premium service excels, while non-premium experiences depend on distributor expertise and sometimes face delays.
Sentiment score
4.3
Trellix ESM customer service is generally satisfactory, but technical support varies with noted delays and skill gaps.
With premium support, core Palo Alto technical experts handle issues directly.
It is ineffective in terms of responding to basic queries and addressing future requirements.
The Palo Alto support team is fully responsive and helpful.
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
6.5
Cortex XSIAM is scalable for various business sizes with cloud-based integration, but lacks on-premises deployment and mixed reviews.
Sentiment score
8.6
Trellix ESM is highly scalable and adaptable, excelling in enterprise environments but may have limitations for medium enterprises.
Without proper integration, scaling up with more servers is meaningless.
Cortex XSIAM is highly scalable.
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
7.6
Cortex XSIAM is praised for its stability, rapid issue resolution, and efficient performance despite minor post-update challenges.
Sentiment score
8.3
Trellix ESM is generally stable with effective support, though some users experience bugs and interruptions affecting reliability.
The product was easy to install and set up and worked right.
Overall, Cortex XSIAM is stable.
It works really nice and performs really efficiently after configuration.
 

Room For Improvement

Cortex XSIAM needs improved integration, performance, interface, pricing, support, ASM, AI, onboarding, tagging, and identity management enhancements.
Trellix ESM requires stability, HTML5 migration, and upgrades in customization, integration, support, usability, and AI for improved functionality.
Obtaining validation for integrations from Palo Alto takes around eight months, which is quite long.
Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports.
Cortex XSIAM is on the expensive side and requires substantial improvement in pricing.
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

Cortex XSIAM is viewed as competitively priced but complex, aligning with market expectations despite some regional variations.
Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
Cortex XSIAM is pretty expensive, and the licensing process is not very comfortable.
The first impression is that XSIAM would be more expensive than others we tried.
The product is very expensive.
 

Valuable Features

Cortex XSIAM excels in machine learning threat detection, SOAR features, and advanced automation for efficient security management.
Trellix ESM excels in real-time threat detection, user-friendly interface, quick deployment, and strong integration with other technologies.
The advanced visualization capabilities of the product are important for understanding security trends in an organization.
One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities.
With Cortex XSIAM, we work with playbooks, and it includes AI to improve threat detection and interaction with 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.

Featured Reviews

AKASH MAJUMDER - PeerSpot reviewer
Incident response times have significantly reduced with efficient device integration and log parsing capabilities
Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports. Additionally, a future update request is to enable tagging of endpoints in groups, similar to a feature available in Cortex XDR. The AI analytics need fine-tuning because some use cases are not working from my side.
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.
