Sentiment score
6.5
Splunk Enterprise Security enhances visibility, improves error resolution, automates processes, and integrates well, though ROI assessment can be challenging.
Using open-source Prometheus saves me money compared to AWS native services.
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
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.
 

Customer Service

Sentiment score
4.0
Prometheus Group support relies on comprehensive documentation and active community forums, praised for their helpfulness and accessibility.
Sentiment score
6.4
Splunk Enterprise Security support is knowledgeable but occasionally slow, with mixed efficiency reviews and valuable community resources.
Prometheus does not offer traditional technical support.
We have paid for Splunk support, and we’re not on the free tier hoping for assistance; we are a significant customer and invest a lot in this service.
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.
 

Scalability Issues

Sentiment score
6.9
Prometheus Group efficiently scales from small to large enterprises, supporting extensive user bases with minimal maintenance required.
Sentiment score
7.5
Splunk Enterprise Security offers scalable, flexible solutions handling large data volumes effortlessly, though cost concerns persist, especially on-premise.
Prometheus is scalable, with a rating of ten out of ten.
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
8.9
Prometheus Group is praised for stability and frequent updates, despite occasional performance issues tied to infrastructure.
Sentiment score
7.6
Splunk Enterprise Security is stable and resilient, though resource-heavy queries can cause occasional bugs, needing optimized use cases.
Deploying it on multiple instances or using Kubernetes for automatic management has enhanced its stability.
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.
I would rate it a ten out of ten for stability.
 

Room For Improvement

Prometheus Group's setup and query language are challenging; improvements needed in UI, documentation, integrations, security, error handling, and pricing.
Splunk Enterprise Security users desire improved GUI, integration, pricing, training, data handling, and advanced features for better efficiency.
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

Prometheus Group is cost-effective due to its open-source nature, preferred over more expensive solutions like New Relic or Datadog.
Splunk Enterprise Security is costly but valued for features and scalability, with pricing concerns for smaller businesses.
Prometheus is cost-effective for me as it is free.
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.
I find it to be affordable, which is why every industry uses it.
 

Valuable Features

Prometheus Group offers robust API integrations, customizable dashboards, scalability, and adaptability, ensuring efficient monitoring across diverse environments.
Splunk Enterprise Security excels in log management, data ingestion, and integration, enhancing security operations with user-friendly features.
It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus.
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.

Free to use and provides valuable monitoring capabilities
Prometheus is a scalable and flexible tool that I can deploy on any cloud platform. It is free to use and provides valuable monitoring capabilities. It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus. The ability to deploy on any cloud platform or environment, including Kubernetes, is a major advantage.
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.

Questions from the Community

What do you like most about Prometheus?
The most valuable feature of Prometheus is its ability to collect metrics.

What SOC product do you recommend?
For tools I’d recommend: -SIEM- LogRhythm -SOAR- Palo Alto XSOAR Doing commercial w/o both (or at least an XDR) is asking to miss details that are critical, and ending up a statistic. Also, rememb...
What is a better choice, Splunk or Azure Sentinel?
It would really depend on (1) which logs you need to ingest and (2) what are your use cases Splunk is easy for ingestion of anything, but the charge per GB/Day Indexed and it gets expensive as log ...
