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
7.5
IBM Security QRadar is praised for efficient monitoring, low costs, valuable analytics, and beneficial long-term security investments.
Sentiment score
7.3
Zabbix, free and open-source, reduces downtime and costs, improving network stability and significant enterprise savings.
With SOAR, the workflow takes one minute or less to complete the analysis.
Investing this amount was very much worth it for my organization.
 

Customer Service

Sentiment score
6.1
IBM Security QRadar's customer service is praised overall, though technical support quality varies, with notable regional differences.
Sentiment score
6.8
Zabbix users praise supportive documentation, community forums, and responsive technical support despite occasional time zone challenges and free version reliance.
Support needs to understand the issue first, then escalate it to the engineering team.
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.
They assist with advanced issues, such as hardware or other problems, that are not part of standard operations.
It is so straightforward that I have never had to use the support.
 

Scalability Issues

Sentiment score
7.4
IBM Security QRadar is scalable and flexible, accommodating thousands of users and devices, though some express pricing concerns.
Sentiment score
6.9
Zabbix is highly scalable, excels in diverse environments, but large deployments may require database optimization for efficient performance.
For EPS license, if you increase or exceed the EPS license, you cannot receive events.
Zabbix has high scalability.
Zabbix is very scalable and lightweight.
I would rate its scalability ten out of ten.
 

Stability Issues

Sentiment score
7.6
IBM Security QRadar is generally stable, though some users face challenges with updates, configurations, scalability, and high log volumes.
Sentiment score
7.5
Zabbix is reliable and resource-efficient, performing well with database tuning and handling heavy workloads without crashing.
The product has been stable so far.
I think QRadar is stable and currently satisfies my needs.
Zabbix is very scalable and lightweight.
Zabbix is quite stable, and we haven't had any problems with Zabbix itself.
 

Room For Improvement

IBM Security QRadar users seek improvements in interface design, integration, automation, cost-efficiency, and advanced analytics for better usability.
Zabbix users seek improved UI, automation, integration, and customization with enhanced reporting, security, and scalability for non-technical users.
IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules.
This would help identify critical or high-priority alarms in QRadar.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
 

Setup Cost

IBM Security QRadar is costly yet efficient, priced on Events Per Second, and offers negotiable, simplified annual licensing.
Zabbix is cost-effective and flexible, offering open-source monitoring with no licensing fees, low expenses, and optional support costs.
Splunk is more expensive than IBM Security QRadar.
 

Valuable Features

IBM Security QRadar is a scalable, user-friendly platform praised for rapid insights, advanced machine learning, and integration capabilities.
Zabbix is valued for open-source customization, scalability, comprehensive monitoring, alerting systems, and cost-effective enterprise IT management.
Recently, I faced an incident, a cyber incident, and it was detected in real time.
I would assess IBM Security QRadar's AI and machine learning capabilities as very helpful for threat detection and response.
We have FortiSOAR and IBM Resilient for IBM Security QRadar orchestration.
If disk usage surpasses a threshold, say 70%, I receive alerts and can take proactive action.
People want to save costs, which is why they install Zabbix, but the reporting functionality is not properly developed.
Zabbix has a lot of features, including monitoring, status updates, and collecting information telemetry from storages and servers as well.

Featured Reviews

Mahmoud Younes - PeerSpot reviewer
Reliable installation and diverse use cases provide strong value
IBM Security QRadar has some areas for improvement. We have missed some DSM components. We need to customize logs where there is no DSM or connector for certain products. We can integrate but we have missed the DSM, which is the connector to pass logs coming from different applications. For example, with a university customer, we tried onboarding Canvas service. IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
B Ahmed - PeerSpot reviewer
