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
6.9
Azure Monitor offers cost-effectiveness and proactive visibility, with pay-as-you-go flexibility and potential savings despite mixed ROI feedback.
Sentiment score
6.5
Splunk Enterprise Security enhances visibility, improves error resolution, automates processes, and integrates well, though ROI assessment can be challenging.
Azure Monitor helps prevent impacts on their system.
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
We couldn't calculate what would have been the cost if they had actually gotten compromised; however, they were in the process, so every investment was returned immediately.
On average, my SecOps team takes probably at least a quarter of the time, if not more, to remediate security incidents with Splunk Enterprise Security compared to our previous solution.
 

Customer Service

Sentiment score
6.2
Azure Monitor support is generally positive, with high-priority users obtaining quicker responses, while others report variable experiences.
Sentiment score
6.4
Splunk Enterprise Security support is knowledgeable but occasionally slow, with mixed efficiency reviews and valuable community resources.
However, the second-line support is good.
Users end up getting no resolution from their team because they're outsourced vendors, and they don't have deeper expertise over any of the products they are referring to.
I would rate the support for Azure Monitor as a seven.
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.
I have had nothing but good experiences with Splunk support, receiving timely and helpful replies.
We've had great customer success managers who have helped us navigate scaling from 600 gigs to 30 terabytes.
 

Scalability Issues

Sentiment score
7.8
Azure Monitor efficiently scales across industries, integrating well with services, and reliably supports growing infrastructure and application needs.
Sentiment score
7.4
Splunk Enterprise Security offers scalable, flexible solutions handling large data volumes effortlessly, though cost concerns persist, especially on-premise.
Azure Monitor is very scalable; there are no issues with scalability for different kinds of businesses.
We currently rely on disaster recovery and backup recovery, which takes time to recover, during which you're basically blind, so I'm pushing my leadership team to switch over to a clustering environment for constant availability.
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.
 

Stability Issues

Sentiment score
8.3
Azure Monitor is stable and reliable with high ratings, but could improve in alerting compared to competitors.
Sentiment score
7.6
Splunk Enterprise Security is stable and resilient, though resource-heavy queries can cause occasional bugs, needing optimized use cases.
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.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
Splunk has been very reliable and very consistent.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
 

Room For Improvement

Azure Monitor requires better integration, user experience, automation, alerting, support, cost clarity, and improved interface and performance monitoring.
Splunk Enterprise Security users desire improved GUI, integration, pricing, training, data handling, and advanced features for better efficiency.
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.
The cost skyrockets once you start using it, and there are complaints that the actual cost of the Kubernetes cluster was less than the cost they were incurring for Azure Monitor.
The challenges with Azure Monitor are that it's initially complex to set up because you need multiple components.
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

Azure Monitor's flexible pricing is generally competitive, but costs can rise due to storage and integration needs.
Splunk Enterprise Security is costly but valued for features and scalability, with pricing concerns for smaller businesses.
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.
I find it to be affordable, which is why every industry uses it.
 

Valuable Features

Azure Monitor provides seamless integration, robust security, dynamic alerting, and efficient reporting, enhancing user satisfaction with scalability and cost-effectiveness.
Splunk Enterprise Security excels in log management, data ingestion, and integration, enhancing security operations with user-friendly features.
The alerting features definitely help in reducing operational downtime for my customers by allowing us to get notifications in advance and take active actions.
Resource monitoring is essential.
The ease of access in Azure is significant because it's native to the platform and easy to integrate.
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.

Native integration simplifies monitoring but documentation and cost improvements are needed
The ease of access in Azure is significant since it's native to the platform and easy to integrate. It has no maintenance overhead, and users don't have to navigate to another portal to get their desired result. It's the handiness that it has, rather than the features. The interpretation from the logs and injection requires custom runbooks. While it's complex, many services provide native insights and workbooks. It does the basic job quite efficiently. They added new kinds of metrics with more integrations to send out metrics. They have even added support for third-party tools that can be integrated. Azure Monitor is working on improvements and becoming more mature. Azure Monitor is stable and scalable. Azure Monitor is evolving with new workbooks and dashboards.

Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

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.
