Splunk Enterprise Security and Microsoft Sentinel are leading solutions in the field of security information and event management (SIEM). Based on feature comparisons, Splunk stands out for its robust data ingestion and comprehensive analytics, while Microsoft Sentinel excels in seamless integration with Azure and cost-effectiveness for users in the Microsoft ecosystem.
Features: Splunk Enterprise Security offers rapid data ingestion, integration with various data sources, and advanced analytics capabilities. It provides exceptional operational intelligence and visualization tools that help organizations diagnose issues quickly. Microsoft Sentinel provides smooth integration with Azure services, strong automation capabilities, and the potential for incident response through Logic Apps. It is ideal for companies already leveraging Microsoft services.
Room for Improvement: Splunk's complexity in operational workflows and the need for GUI and cluster management enhancements are noted. Users report challenges in report building and visualization. Sentinel can improve support for non-Microsoft environments and expand native device integrations. Simplifying dashboard creation and achieving a consistent user interface is recommended.
Ease of Deployment and Customer Service: Splunk supports deployment across on-premises, cloud, and hybrid environments but requires skilled personnel due to configuration complexity. It has variable support response times. Microsoft Sentinel offers ease of deployment in Azure, benefiting from seamless integration with Microsoft services and robust scalability. Users appreciate its straightforward setup and reliable support from Microsoft.
Pricing and ROI: Splunk is considered a premium solution with a high cost structure mainly due to its data ingestion-based pricing, which may be concerning for smaller enterprises. Microsoft Sentinel's subscription-based model is more cost-effective, especially for those investing in Azure. While both solutions enhance security posture and operational efficiency, Sentinel offers an attractive price point for businesses aligned with Microsoft cloud services.
Splunk's cost is justified for large environments with extensive assets.
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.
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.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
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.
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.
This capability is useful for performance monitoring and issue identification.
The Splunk Enterprise Security's threat-hunting capabilities have been particularly useful in later releases.
Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language.
