Sentiment score
7.2
Splunk Enterprise Security boosts ROI with improved efficiency, error handling, and automation, reducing costs and streamlining operations.
The solution is time-saving, particularly in the long run after it is deployed, enabling us to get value promptly.
I have noticed a return on investment with Splunk Enterprise Security, as it delivers substantial value for money.
Customers see the value in investing in this solution, particularly when it helps resolve issues quickly, turning a potential 20-hour response into one hour.
We are able to secure the environment from all security threats and maintain an environment that is free from threats and attacks, especially cyberattacks.
 

Customer Service

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 receives high praise for support quality, though response times may vary; documentation and community are beneficial.
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
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 is scalable, integrates well, handles large data efficiently, but may incur costs, especially for on-premises setups.
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
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 its stability, reliability, and scalability, with large enterprises highlighting its exceptional performance.
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

Securonix Next-Gen SIEM struggles with complex deployment, integration, usability, and needs improvements in reporting, support, pricing, and performance.
Splunk Enterprise Security needs cost-effective improvements in analytics, user interface, integrations, threat detection, and overall performance for better user experience.
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

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 pricing is seen as prohibitive, especially for small businesses, requiring careful cost-benefit evaluation.
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

Securonix Next-Gen SIEM offers advanced threat detection, automation, and integration, enhancing security while reducing manual tasks and response times.
Splunk Enterprise Security excels in search, data integration, real-time monitoring, and enhances threat detection and compliance management.
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.

Featured Reviews

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.
