Executive SummaryUpdated on Oct 19, 2025
html

Splunk Enterprise Security and Microsoft Sentinel compete in security-oriented data analysis. Microsoft Sentinel might have an upper hand for businesses using Microsoft ecosystems due to its seamless integration and cloud-native benefits.

Features: Splunk Enterprise Security provides detailed data analysis, extensive integration options, and advanced risk-based alerting. Features like visual agent deployment and operational intelligence cater to complex environments. Microsoft Sentinel offers smart threat detection, cloud-native benefits, and effective integration with Microsoft tools, enhancing user experience for those invested in Microsoft products.

Room for Improvement: Splunk Enterprise Security could benefit from enhancing its user interface by reducing the learning curve, and offering more intuitive functionalities. Improved pricing models and better cloud integration are desired by users. Microsoft Sentinel needs to expand integration capabilities to non-Microsoft applications, offer better customization options, and address regional operational issues.

Ease of Deployment and Customer Service: Splunk Enterprise Security offers versatile deployment across on-premises and hybrid clouds, though this can increase complexity and require substantial expertise. Its customer service response varies, possibly due to rapid growth. Microsoft Sentinel, with its cloud-native design, simplifies deployment and integrates efficiently within Microsoft services but could improve tech support speed and quality.

Pricing and ROI: Splunk Enterprise Security is perceived as costly, particularly with its data ingestion-based pricing model affecting affordability for smaller businesses. However, it offers significant ROI due to comprehensive features. Microsoft Sentinel provides a more flexible pricing structure within the Azure environment, offering a cost-effective solution with substantial ROI, especially appealing for organizations utilizing Microsoft tools.

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.

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.

Room For Improvement

Sentinel requires improved web integration, user interface, customization, documentation, and dashboard simplicity, while addressing regional outages and cost concerns.
Splunk Enterprise Security needs enhanced UI, simpler setup, better training, flexible pricing, improved integration, permissions, AI, and dashboards.
Price is always a consideration, so the price would be nice if it were lower.
For more quotes and insights, download the Sentinel report
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.

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.

Featured Reviews

Simon Johnston - PeerSpot reviewer
Simple antivirus solution integrates well but could improve pricing and currency options
I don't really have experience working with these solutions. I promote them for our clients, but I don't work with them. I can't share my experience with these tools as I make assumptions about that. For both Adlumin and CrowdStrike, both confirm that they're scalable and enterprise-ready and all those kinds of things. We haven't had any specific problem with either of those. We just have a preference for which one we would prefer. If somebody says they want to use a different one from the one that we prefer, then we have to find reasons why they aren't. But scalability is not one of the reasons that one is better over the other. I don't really have advice for people that are looking into using Sentinel; just do your research across what is available. On a scale of one to ten, I rate Sentinel a seven.

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.
