It is ineffective in terms of responding to basic queries and addressing future requirements.

I had a dedicated person allocated for supporting, and even with them, it was very good.

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
6.6
Cortex XSIAM excels in scalability and cloud deployment, though integration affects performance and some prefer more on-premises functionality.

Trellix ESM is highly scalable and adaptable, excelling in enterprise environments but may have limitations for medium enterprises.

Cybersecurity Architect at a computer software company with 10,001+ employees
Cortex XSIAM is highly scalable.

Room For Improvement

Cortex XSIAM needs better integration, usability, pricing, data management, and support for enhanced performance and flexibility.
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.
Associate Director at a financial services firm with 5,001-10,000 employees
Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports.
SOC Analyst at OVELOSEC
Cortex XSIAM is on the expensive side and requires substantial improvement in pricing.
Solutions Architect at ostec
If there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
 

Setup Cost

Cortex XSIAM is expensive with variable pricing, complexity in licensing, and additional costs for functionalities and resources.
Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
The first impression is that XSIAM would be more expensive than others we tried.
Owner at Xelere
The product is very expensive.
Associate Director at a financial services firm with 5,001-10,000 employees
Cortex XSIAM is pretty expensive, and the licensing process is not very comfortable.
Director at MICROLOGIC NETWORKS PRIVATE LIMITED
 

Valuable Features

Cortex XSIAM enhances incident response with automation, integration, and machine learning, providing comprehensive network security and threat identification.
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.
Solutions Architect at ostec
To have Cortex XSIAM available is to basically have integration of all log sources, all alerting, and so on and so forth from firewalls and different tools, to get everything in one place, and afterwards to be able to build on the information that is coming.
Cybersecurity Architect at a computer software company with 10,001+ employees
One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities.
Owner at Xelere
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.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.

Cybersecurity Architect at a computer software company with 10,001+ employees
Unified security monitoring has simplified incident response and improved automated threat handling
The firewall side can make some improvements. I know the firewall on Cortex XSIAM is based on Windows. From what I have experienced so far, I have seen that the policies you can create are actually very in-depth. I mean, you can do most of the things and a lot of integration that you actually want. So if I want to choose to send things to WildFire, for example, I can choose to send it, I can choose to not send it. This basically offers flexibility to implement Cortex XSIAM in more standardized places where you maybe have a certification. I would say that the thing that maybe needs a bit more improvement is the fact that the one with the firewall because I have seen some things there that are kind of hard to manage. You do not really have a very easy way to manage those, unless you actually know where you have put them. So it is very inflexible. In the rest, you have a lot of playbooks that you can do and you can do lots of automation, which is actually easy to manage from what I have seen from my colleagues.

Offers comprehensive report generation while maintaining ease of integration
We need to improve Trellix ESM by making sure that most of the logging devices available in the global market should be covered, and if there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that. We can add some new features regarding AI in the future for Trellix ESM, but the maturity will take a longer time. There are many false positives that happen in an environment during the first couple of months, or around six months, so the system analyst is not able to identify whether the event which has occurred is a true positive or a false positive.
