Customer Service

Sentiment score
6.9

Sentiment score
5.7
OpenText Enterprise Security Manager's service is satisfactory but faces issues with technical support consistency and problem management resolution.
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.
If I raise a P1 or P0 ticket, the response time is often delayed by four to eight hours.

Sentiment score
7.1
OpenText Enterprise Security Manager offers strong scalability but is costly, requiring expertise and careful budgeting for extensive deployments.
LogRhythm SIEM is scalable; it can handle about 200 or 500 devices without much difference.
LogRhythm SIEM is highly scalable as it has modular components allowing me to expand storage, indexing, or other resources as needed.
It lacks some capabilities compared to other tools available in the market.
 

Stability Issues

4.4
LogRhythm SIEM is generally stable, reliable, and efficient, with some performance issues resolved through updates and proper resource allocation.

OpenText Enterprise Security Manager is reliable but depends on proper setup; issues are rare when optimized correctly.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
The stability of ArcSight Enterprise Security Manager (ESM) is not very robust.
 

Room For Improvement

LogRhythm SIEM needs better integration, UI improvements, enhanced reports, and Linux-based support for efficiency and tool integration.
OpenText Enterprise Security Manager needs UI upgrades, performance improvements, better integration, support, deployment, analytics, and scalability enhancements.
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.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
The integration aspect of ArcSight Enterprise Security Manager (ESM) needs improvement.
 

Setup Cost

LogRhythm SIEM offers competitive pricing with comprehensive features, though scalability and additional features may increase costs.
OpenText Enterprise Security Manager pricing, while high, is justified by its robust features and deemed competitive for enterprise needs.
The license cost is around $10 per MPS.
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.

Valuable Features

LogRhythm SIEM excels in threat detection, user-friendly interface, and integration, offering centralized logs and customizable alerts.
OpenText Enterprise Security Manager offers powerful integration, real-time threat detection, customization, and robust event management for security teams.
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.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
The ability to interpret data is highly valued.

User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.
Gaurav Ranade - PeerSpot reviewer
Excels at performing regression and correlation on the data
ArcSight is a legacy technology, and many customers want AI-powered technologies integrated with it. That hasn't been done yet, but ArcSight needs to catch up with the newer solutions and technologies available in the market. It can't just rely on the legacy technology from 2010 or 2012. You can't run that in 2024. It's a legacy technology with its own limitations. Customers often face issues that other software or newer solutions can resolve easily. That's the main challenge we face from customers right now. So, the only concerns are that AI needs to be integrated and scalability improved. Those are the main areas to be improved.
