Customer Service

Sentiment score
6.9
LogRhythm SIEM's support is knowledgeable and responsive, though consistency and initial response times need improvement.
Sentiment score
6.7
Securonix Next-Gen SIEM excels in customer service with high satisfaction ratings, proactive guidance, and effective issue resolution.
Sentiment score
6.7
Splunk Enterprise Security support praised for knowledge and speed, but response times and complexity vary, premium options recommended.
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.
There is no UK-based support, which leads to delays in waiting for US support.
If I raise a ticket, it initially goes to the L1 team, but the next level of escalation is really effective.
When we reach out to someone, we often wait for the right person with the right skills to come and fix the solution, which is the major challenge.
If you want to write your own correlation rules, it is very difficult to do, and you need Splunk's support to write new correlation rules for the SIEM tool.
They try to close issues as soon as possible, often just offering documentation links.
They are responsive and effectively resolve issues.
 

Scalability Issues

Sentiment score
7.6
LogRhythm SIEM is praised for its strong scalability and effectiveness in accommodating expanding demands across diverse environments.
Sentiment score
8.0
Securonix Next-Gen SIEM offers efficient scalability with flexible options, resolving slowdowns swiftly for diverse operational needs.
Sentiment score
7.7
Splunk Enterprise Security efficiently scales across environments, supporting large data volumes despite cost concerns, offering robust architecture.
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.
I can rate it around eight to nine, and it is very scalable and capable of handling tasks, especially for the on-premises product.
The solution is scalable as it is cloud-based and cloud-native.
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
It is easy to scale.
It's big in a Central European context, and small from a Splunk North American context.
 

Stability Issues

Sentiment score
4.4
LogRhythm SIEM is generally stable, reliable, and efficient, with some performance issues resolved through updates and proper resource allocation.
Sentiment score
7.8
Securonix Next-Gen SIEM is stable with high availability, efficient log management, and high user satisfaction despite occasional issues.
Sentiment score
7.9
Splunk Enterprise Security is praised for stability and reliability, with minor bugs manageable under efficient configuration and resource management.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
The stability of Securonix Next-Gen SIEM is based on the events we are processing.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
 

Room For Improvement

LogRhythm SIEM needs better integration, UI improvements, enhanced reports, and Linux-based support for efficiency and tool integration.
Securonix Next-Gen SIEM struggles with complex deployment, integration, usability, and needs improvements in reporting, support, pricing, and performance.
Splunk Enterprise Security needs improvements in rule engine, integration, cost-effectiveness, dashboard complexity, performance, customization, interface, and user training.
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.
At the admin level, we have many challenges where log parsing is causing issues and compatibility is not present.
The passing and setup are quite complex at the beginning, making onboarding not smooth.
SIEM could have better integration with other technologies.
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Splunk Enterprise Security is not something that automatically picks things; you have to set up use cases, update data models, and link the right use cases to the right data models for those detections to happen.
For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.
 

Setup Cost

LogRhythm SIEM offers competitive pricing with comprehensive features, though scalability and additional features may increase costs.
Securonix Next-Gen SIEM offers competitive, predictable pricing based on employee count, with typical enterprise costs around $100,000 for three years.
Splunk Enterprise Security's high costs deter smaller enterprises, yet its features often justify the expense for larger organizations.
The license cost is around $10 per MPS.
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.
Licensing is based on events per second (EPS), costing between $50 to $60 per EPS.
The pricing has similar ingestion charges compared to other solutions, such as Splunk.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
Splunk is priced higher than other solutions.
 

Valuable Features

LogRhythm SIEM excels in threat detection, user-friendly interface, and integration, offering centralized logs and customizable alerts.
Securonix Next-Gen SIEM offers advanced threat detection, automation, and integration, enhancing security while reducing manual tasks and response times.
Splunk Enterprise Security offers fast data search, scalable log management, real-time alerts, and seamless third-party integration, enhancing threat detection.
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.
The software includes user behavior interactions, dashboards, and training capabilities.
Now, the process is automatic, reducing our workload.
The other SIEM solutions lack an option for big data analysis, whereas in the Securonix Next-Gen SIEM, we have this option.
This capability is useful for performance monitoring and issue identification.
I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.
Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues.

Mokhammad Rakhman - PeerSpot reviewer
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.
Mohammed Nadeem Rais - PeerSpot reviewer
The visibility and analytics from Securonix SIEM have become indispensable in identifying and stopping potential threats before they escalate.
The most valuable feature of Securonix Next-Gen SIEM is its advance analytics, flexibility and scalability. We ingest billions of logs without worrying about resource allocation. This makes it a robust and cost-effective solution for our needs. Its user entity and behavior analytics (UEBA) are also integral for detecting insider threats and lateral movements within the organization. These features help organizations strengthen their security posture, protect sensitive data, and maintain compliance with strict regulatory requirements.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.
