Cyber Security Architects at VaporVM
AWS gives the chance to implement a solution out of the box with use cases that are already in IBM Security QRadar.
Strategic Account Executive at a computer software company with 51-200 employees

Customer Service

Sentiment score
6.0
IBM Security QRadar support quality varies, with inconsistent service; knowledgeable agents appreciated but response times and expertise are concerns.
Sentiment score
4.3
Trellix ESM customer service is generally satisfactory, but technical support varies with noted delays and skill gaps.
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.
IT Solutions Product Manager at a computer software company with 11-50 employees
There is a knowledgeable, though small, team of support engineers around the world.
Network Engineer at Laminar Communications Pty Ltd
They take some time to respond because they need logs and investigations, which delays the response time.
Network Engineer at Ogma Consulting
They assist with advanced issues, such as hardware or other problems, that are not part of standard operations.
Network and Security Architect at Deutsche Telekom
Support needs to understand the issue first, then escalate it to the engineering team.
Cyber Security Architects at VaporVM
The support is really good; for instance, if a critical ticket is submitted, you will get paged right away as it gets logged, and their analyst will look into it, letting you know as soon as possible so you can work on it.
Cyber Security Intern at a retailer with 1,001-5,000 employees
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.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
It's rare for me to need them unless it's an issue with licensing, and they are the best in that regard.
Cyber Security Engineer at Protec

7.6
Fortinet FortiSIEM scales well, accommodating different business sizes but faces challenges with licensing, architecture, and configuration complexities.

Sentiment score

Fortinet FortiSIEM is highly scalable.
Network Engineer at Laminar Communications Pty Ltd
Fortinet FortiSIEM is easy to scale.
Network Engineer at Ogma Consulting
For EPS license, if you increase or exceed the EPS license, you cannot receive events.
Cyber Security Architects at VaporVM
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.
Senior Vice President IT at AS IT Consulting Pvt. Ltd.

The product has been stable so far.

Room For Improvement

Fortinet FortiSIEM needs improvements in integration, user interface, support, cost, and features like AI and automated responses.
IBM Security QRadar needs UI improvements, better integration, faster support, enhanced features, and competitive pricing to address user concerns.
Trellix ESM requires stability, HTML5 migration, and upgrades in customization, integration, support, usability, and AI for improved functionality.
Recently, they revised it to a subscription-based, all-inclusive license.
IT Solutions Product Manager at a computer software company with 11-50 employees
The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products.
Network Engineer at Laminar Communications Pty Ltd
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management.
Network Engineer at Ogma Consulting
We receive logs from different types of devices and need a way to correlate them effectively.
Network and Security Architect at Deutsche Telekom
If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules.
Information Security Analyst at Banglalink
IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
Cyber Security Architects at VaporVM
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

Fortinet FortiSIEM provides flexible pricing that can be cost-effective, but costs may increase with additional modules and scalability.
IBM QRadar is costly but efficient, flexible in licensing, negotiable, and ideal for large enterprises over smaller ones.
Trellix ESM offers flexible, slightly costly licensing, valued for its SOC features, with straightforward setup and deployment.
Setting it up for oneself as an enterprise-licensed product can be quite expensive.
Network Engineer at Laminar Communications Pty Ltd
Windows agent licenses cost around 3,000 Rupees per device per year.
Network Engineer at Ogma Consulting
The revised model is subscription-based and more flexible.
IT Solutions Product Manager at a computer software company with 11-50 employees
Splunk is more expensive than IBM Security QRadar.
Cyber Security Architects at VaporVM
It was costly mainly because of the value you can get right now compared to other solutions.
CTO at Sabyk
It depends on how much you want to spend.
Strategic Account Executive at a computer software company with 51-200 employees
 

Valuable Features

Fortinet FortiSIEM provides automation, analytics, and integration with a user-friendly interface for efficient threat detection and network monitoring.
IBM Security QRadar is scalable and user-friendly, excelling in threat detection, event analysis, and third-party integration for large operations.
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.
Network Engineer at Laminar Communications Pty Ltd
I find the real-time monitoring and correlation capabilities effective for security alerts.
Network Engineer at Ogma Consulting
Recently, I faced an incident, a cyber incident, and it was detected in real time.
Information Security Analyst at Banglalink
IBM Security QRadar gives the opportunity to improve the time to market of the releases with a great evaluation of cybersecurity breaches.
Strategic Account Executive at a computer software company with 51-200 employees
Compared to ArcSight, Splunk, or any other SIEM tools where you need their processing language such as structured query language, SPL, and in Sentinel there is KQL query languages, IBM Security QRadar doesn't require reliance on query languages.
SOC Engineer at a outsourcing company with 10,001+ employees
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.

Network Engineer at Ogma Consulting
Comprehensive monitoring boosts security, yet incident management features need expansion
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR. Additionally, the search functionality in FortiAI should be improved to provide more precise results, making it easier for me to understand what actions need to be taken.
HarshBhardiya - PeerSpot reviewer
SOC Engineer at a outsourcing company with 10,001+ employees
Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.
MD
Senior Vice President IT at AS IT Consulting Pvt. Ltd.
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.
