Customer Service

Sentiment score

Prometheus Group support relies on comprehensive documentation and active community forums, praised for their helpfulness and accessibility.
Sentiment score
6.7
Splunk Enterprise Security support is mixed: knowledgeable at higher levels but variable with first-tier responses, praised online.
Prometheus does not offer traditional technical support.
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.
The technical support for Splunk met my expectations.
 

Scalability Issues

Sentiment score

Prometheus is scalable, with a rating of ten out of ten.
It is easy to scale.
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
 

Stability Issues

Sentiment score
8.9
Prometheus Group is praised for stability and frequent updates, despite occasional performance issues tied to infrastructure.
Sentiment score
7.9
Splunk Enterprise Security is reliable and adaptable, handling large data volumes with minimal downtime and robust performance.
Deploying it on multiple instances or using Kubernetes for automatic management has enhanced its stability.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
 

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 needs improved setup, GUI, user control, pricing, machine learning, and intuitive dashboards for better accessibility.
Splunk Enterprise Security would benefit from a more robust rule engine to reduce false positives.
What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel.
Data retention can be better. If we want to look at the data for five months or six months, that is not available to us. We only have a history of 20 or 30 days.
 

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, offering significant ROI with careful data management.
Prometheus is cost-effective for me as it is free.
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
Splunk is priced higher than other solutions.
 

Valuable Features

Prometheus Group offers robust API integrations, customizable dashboards, scalability, and adaptability, ensuring efficient monitoring across diverse environments.
Splunk Enterprise Security enhances threat detection with fast data retrieval, customizable visualizations, and seamless third-party integration for efficient operations.
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.
They have approximately 50,000 predefined correlation rules.
Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language.

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.
