Sentiment score
5.4
LogRhythm SIEM's support excels in expertise and quick resolutions, earning high satisfaction despite occasional delays.
Sentiment score
6.7
OpenText Behavioral Signals' support is responsive and skilled, but resolution may be slow and feedback sometimes lacks depth.
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.
The technical support is good; we have a separate portal for partners, and since we are paying for the service, they provide a response timeframe based on severity—critical issues are addressed within four hours, medium issues within one day, and non-urgent issues may take a couple of days.
Customer support is very helpful and effectively solves my problems.
 

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
7.8
LogRhythm SIEM is highly scalable, easily expands across environments, and integrates well, suitable for medium to large enterprises.
Sentiment score
6.3
OpenText Behavioral Signals faces scalability challenges, while technologies like ArcSight Intelligence excel, prompting consideration of alternatives like Splunk.
For EPS license, if you increase or exceed the EPS license, you cannot receive events.
LogRhythm SIEM is highly scalable as it has modular components allowing me to expand storage, indexing, or other resources as needed.
LogRhythm SIEM is scalable; it can handle about 200 or 500 devices without much difference.
The scalability of LogRhythm SIEM is good enough, warranting an eight out of ten rating.
 

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
4.7
LogRhythm SIEM is stable with high uptime, strong support, handling large data, though updates may affect stability.
Sentiment score
8.4
OpenText Behavioral Signals is praised for its stability, receiving high ratings and fostering user trust through reliable performance.
I think QRadar is stable and currently satisfies my needs.
The product has been stable so far.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
LogRhythm SIEM still needs improvement regarding stability, particularly in environments with heavy data consumption.
 

Room For Improvement

IBM Security QRadar users seek improvements in interface design, integration, automation, cost-efficiency, and advanced analytics for better usability.
LogRhythm SIEM needs improved integration, user interface, automation, scalability, documentation, and compatibility with non-mainstream platforms and Linux.
OpenText and ArcSight require updates for usability, scalability, and pricing to compete with QRadar and Splunk effectively.
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.
I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.
There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
 

Setup Cost

IBM Security QRadar is costly yet efficient, priced on Events Per Second, and offers negotiable, simplified annual licensing.
LogRhythm SIEM is cost-effective for enterprises, offering transparent pricing and flexible licensing, yet incurs higher professional service fees.
OpenText Behavioral Signals offers enterprise-priced licensing options with additional charges for new features not in the base license.
Splunk is more expensive than IBM Security QRadar.
The license cost is around $10 per MPS.
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.
 

Valuable Features

IBM Security QRadar is a scalable, user-friendly platform praised for rapid insights, advanced machine learning, and integration capabilities.
LogRhythm SIEM offers advanced threat detection, user-friendly interface, comprehensive log management, and automated alerts for enhanced security efficiency.
OpenText Behavioral Signals synthesizes diverse logs, customizes environments, and enhances efficiency with a user-friendly, consolidated interface.
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.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
We have enough budget for cloud deployment, but we choose to keep it on-prem to ensure data privacy; cyberattacks are a concern, but data privacy is the foremost priority due to sensitive government information.
This helps SOC analysts significantly as they can monitor all log sources through a dashboard, quickly identifying which sources haven't reported within their specified timeframes.

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.
SumitKumar20 - PeerSpot reviewer
Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.
Nagendra Nekkala - PeerSpot reviewer
A user-friendly solution that can be used to integrate the logs properly with different connectors
ArcSight Intelligence is easy to maintain; one person is enough for the solution's maintenance. The maintenance person will add new features or devices, make policy changes or configurations, and learn and guide other engineers about new threats. ArcSight Intelligence is a user-friendly solution, and users should buy it if their company can afford its cost. Overall, I rate ArcSight Intelligence a nine out of ten.
