Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.0
Azure Monitor provides real-time insights with mixed financial gains, offering significant savings when integrated with Microsoft products.
Sentiment score
7.2
Splunk Enterprise Security enhances efficiency, reduces costs and personnel, boosts revenue, automates processes, and improves data management for users.
Splunk's cost is justified for large environments with extensive assets.
 

Customer Service

Sentiment score
6.2
Azure Monitor support receives mixed reviews; premium users report better service, but delays and limited technical depth remain issues.
Sentiment score
6.7
Splunk Enterprise Security offers knowledgeable support but encounters response delays, leading users to seek help from community forums.
However, the second-line support is good.
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
7.7
Azure Monitor is valued for scalability, cloud flexibility, and integration, effectively suiting diverse organizational needs despite some challenges.
Sentiment score
7.7
Splunk Enterprise Security is praised for scalability across environments, though on-prem expansion may face cost and planning challenges.
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
8.3
Azure Monitor is stable, reliable, regularly updated, rated highly in stability, and appreciated across various business scales.
Sentiment score
7.9
Splunk Enterprise Security is stable and reliable, handling large data efficiently, but requires careful capacity planning for complex queries.
Azure Monitor is working fine, yet I face a costing issue as if there are a lot of logs collected in the workspace or in the center, it becomes very costly.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
 

Room For Improvement

Azure Monitor users desire better integration, support, AI capabilities, and expanded features for enhanced monitoring and user experience.
Splunk Enterprise Security requires UI, integration, and documentation improvements; users seek better performance, visualizations, licensing, and automation features.
If Azure Monitor can independently add one gigabyte, two gigabytes, or five gigabytes at least to log storage, I can fix the logs without syncing with Log Analytics Workspace and Sentinel.
What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel.
Splunk Enterprise Security would benefit from a more robust rule engine to reduce false positives.
Splunk could enhance its offerings by incorporating modules for network detection and response and fraud management.
 

Setup Cost

Azure Monitor is cost-effective for Azure clients, offering competitive pricing with pay-as-you-go and expense estimation tools.
Splunk Enterprise Security provides robust features but is costly, especially for small organizations, with complex licensing and potential savings.
When I export logs into the application, workspace, log analytic workspace, and into Sentinel to read reports, I need to add storage, which increases the cost.
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

Azure Monitor provides comprehensive monitoring, dynamic alerts, and easy integration with Azure services, supporting infrastructure and application performance.
Splunk Enterprise Security offers quick data search, integration, real-time alerts, and customizable dashboards for effective multi-cloud threat management.
Resource monitoring is essential.
Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language.
The Splunk Enterprise Security's threat-hunting capabilities have been particularly useful in later releases.
They have approximately 50,000 predefined correlation rules.

While both are Application Lifecycle Management solutions, they serve different purposes. Azure Monitor is designed for Application Performance Monitoring (APM) and Observability and holds a mindshare of 8.0%, down 8.7% compared to last year.
Splunk Enterprise Security, on the other hand, focuses on Security Information and Event Management (SIEM), holds 9.8% mindshare, down 13.5% since last year.

Monthly and weekly resource monitoring has improved efficiency
Azure Monitor can improve by adding some kind of storage for logs. I can get the runtime logs alone, yet if Azure Monitor can independently add one gigabyte, two gigabytes, or five gigabytes at least to log storage, I can fix the logs without syncing with Log Analytics Workspace and Sentinel. If they do that, and if they can integrate a little pricing adjustment, it will be profitable for the Microsoft tool.
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.

Splunk handles a high amount of data very well. We use Splunk to capture information and as an aggregator for monitoring information from different sources. Splunk is very good at alerting us if we have problems somewhere or if we are not getting the flow we expect. It is very easy to search for queries and events and then do analysis. The flexibility of the search capability is extremely valua...

Splunk handles a high amount of data very well. We use Splunk to capture information and as an aggregator for monitoring information from different sources. Splunk is very good at alerting us if we have problems somewhere or if we are not getting the flow we expect. It is very easy to search for queries and events and then do analysis. The flexibility of the search capability is extremely valuable. Splunk works well with other solutions. It is very easy to set up and very straightforward to deploy. The more data you process with Splunk, the more expensive it gets; an improved pricing model is needed. It would be great if Splunk had more SIEM functionality with better customization and a better ticket tool. The on-premises scaling is a bit more limited than on the cloud. Splunk currently has some limited default rules and customizations. If they could concentrate more on compliance and security information, that would be an added bonus. Azure Monitor has made it significantly easier for us to monitor applications and infrastructure for possible problems. This solution offers a survey of surveillance in real time and a very helpful dashboard. Azure Monitor, which is integrated with Azure DevOps, has good load gathering and very good analytics. We get useful alerts with Azure Monitor that make recommendations about the security and the platform. There should be more specific detail about where problems lie. Azure Monitor is lacking somewhat in vulnerability assessment; this aspect could be better. Their automation also needs some improvement. From gathering metrics from more applications to getting processes quickly started when something goes down, automation should be better. Conclusion: For us, Splunk is the better solution. We use Splunk to search, monitor, analyze, and visualize machine data, which it does very well. The dashboard is very intuitive. The log collection and log management tools are very good. We find Splunk’s search capability to be very powerful and flexible. Splunk can access any kind of data and there is no limitation to the kind of structured or unstructured data you can extract. Our team also liked that Splunk offers better integration with more solutions.
