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
6.7
Microsoft Defender XDR provides high ROI by consolidating security tools, streamlining operations, and enhancing security, despite licensing costs.
With SOAR, the workflow takes one minute or less to complete the analysis.
Investing this amount was very much worth it for my organization.
We can quarantine and isolate a device within minutes.
Microsoft Defender XDR has saved me at least 50% of my time.
Ever since we turned on the M5 feature set back in June, we have seen a reduced number of potentially malicious clicks and faster alerting when incidents occur.
 

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
6.2
Microsoft Defender XDR's support is timely and responsive, yet smaller organizations experience slower, less effective assistance than larger ones.
They assist with advanced issues, such as hardware or other problems, that are not part of standard operations.
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.
You get stuck in low-level support for way longer than you should, instead of them escalating the issue up the chain.
It's critical to escalate SEV B issues immediately to a domestic engineer.
Once issues are escalated to the second or third layer, the support is much better.
 

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
7.6
Microsoft Defender XDR scales well for various organizations, efficiently supporting growth and flexibility despite some network deployment challenges.
For EPS license, if you increase or exceed the EPS license, you cannot receive events.
Microsoft Defender XDR shows tremendous scalability, much more so than on-premises solutions.
Microsoft Defender XDR scales pretty well.
It is suitable for enterprise-level deployment but has room for improvement.
 

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
8.0
Microsoft Defender XDR is praised for high stability, reliable performance, minimal issues, frequent updates, and prompt issue resolution.
I think QRadar is stable and currently satisfies my needs.
The product has been stable so far.
The service has remained consistently online, with any issues isolated to specific components, suggesting a well-designed and modular architecture.
The services within our ecosystem have been reliable, meeting their SLAs.
It provides high-fidelity signals.
 

Room For Improvement

IBM Security QRadar users seek improvements in interface design, integration, automation, cost-efficiency, and advanced analytics for better usability.
Microsoft Defender XDR requires enhancements in speed, integration, automation, AI, ease-of-use, and industry-specific threat intelligence.
We receive logs from different types of devices and need a way to correlate them effectively.
If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules.
IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
The licensing process needs improvement and clarification.
Improvements are needed in automated response capabilities.
Some inconsistencies exist between blades, which could be improved for a more seamless user and UI experience.
 

Setup Cost

IBM Security QRadar is costly yet efficient, priced on Events Per Second, and offers negotiable, simplified annual licensing.
Microsoft Defender XDR pricing is seen as complex but fair, with high costs alleviated in bundled Microsoft 365 packages.
Splunk is more expensive than IBM Security QRadar.
There are certainly savings when using Microsoft Defender XDR, which can range from 30%, 40%, and even up to 50%.
I would rate the pricing as eight out of ten, indicating it is a reasonable cost for the product.
Microsoft purposefully obfuscates this through marketing ploys to hide costs.
 

Valuable Features

IBM Security QRadar is a scalable, user-friendly platform praised for rapid insights, advanced machine learning, and integration capabilities.
Microsoft Defender XDR integrates tools for comprehensive security, offering threat detection, automation, identity protection, and enhanced efficiency.
Recently, I faced an incident, a cyber incident, and it was detected in real time.
IBM is seeking information about IBM QRadar because a part of QRadar, especially in the cloud, has been sold to Palo Alto.
We have FortiSOAR and IBM Resilient for IBM Security QRadar orchestration.
With Microsoft threat intelligence information, it detects various types of threats, including insider attacks, malicious content, and data exfiltration.
This allows us to secure our systems in advance and proactively improve security, rather than waiting for incidents to occur.
Once we have it on the security dashboard, we can see a real-time storyline.

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.
MohtesanShaikh - PeerSpot reviewer
Experience improves security management and simplifies threat protection
I have created automated investigations, and while they work, they operate rather slowly in the Microsoft portal. If I automate something, it takes considerable time; if I do it manually, I can complete it in a quarter of the time. The automation response being slow is the main concern; when an incident occurs or if I run a remediation, it takes significant time to complete the remediation. There are some limitations regarding the scalability of Microsoft Defender XDR with specific licensing. For SMB customers, there is only Microsoft Defender for Business, and if they want more features such as XDR features and automation investigation or incident response, they need to purchase Defender for Endpoint. We are currently using the EDR.
