Splunk Enterprise Security and Sentinel are prominent contenders in the SIEM landscape. Splunk seems to have the upper hand due to its strong data collection and integration capabilities, as well as its advanced search functionality, which are crucial for complex environments.
Features: Splunk offers robust data collection capabilities, extensive integration options, and a rapid search feature, making it adaptable to complex environments. It also provides advanced threat detection and customization options. Sentinel excels in cloud-native operations with seamless Azure integration and offers built-in machine learning capabilities for efficient threat correlation and alerting.
Room for Improvement: Splunk is challenged by its complexity and high learning curve, deterring new users, and incurs high costs due to data ingestion fees. It also requires improved AI-driven features for predictive threat detection. Sentinel needs expanded integration beyond Microsoft's ecosystem, better support for diverse device connectors, and enhancements in visualization tools and multi-tenancy features.
Ease of Deployment and Customer Service: Both Splunk and Sentinel offer deployment flexibility across on-premises, cloud, and hybrid environments. Splunk benefits from extensive documentation and an active user community, though its complexity requires expert setup. Sentinel, being cloud-native, simplifies deployment, especially for Azure users, with robust support from Microsoft's infrastructure.
Pricing and ROI: Splunk is often seen as expensive due to its data volume-based pricing, significantly impacting organizations with large data sets. However, its powerful features justify the cost for many. Sentinel offers an affordable cloud-based option with a pay-as-you-go model, appealing to cost-conscious organizations, with potential savings for those using Azure.
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.
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.
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.
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.
Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language.
They have approximately 50,000 predefined correlation rules.
The Splunk Enterprise Security's threat-hunting capabilities have been particularly useful in later releases.
Sentinel is a full-featured Security Information and Event Management (SIEM) solution that simplifies the deployment, management and day-to-day use of SIEM, readily adapts to dynamic enterprise environments and delivers the true "actionable intelligence" security professionals need to quickly understand their threat posture and prioritize response.
Splunk Enterprise Security is widely used for security operations, including threat detection, incident response, and log monitoring. It centralizes log management, offers security analytics, and ensures compliance, enhancing the overall security posture of organizations.
Companies leverage Splunk Enterprise Security to monitor endpoints, networks, and users, detecting anomalies, brute force attacks, and unauthorized access. They use it for fraud detection, machine learning, and real-time alerts within their SOCs. The platform enhances visibility and correlates data from multiple sources to identify security threats efficiently. Key features include comprehensive dashboards, excellent reporting capabilities, robust log aggregation, and flexible data ingestion. Users appreciate its SIEM capabilities, threat intelligence, risk-based alerting, and correlation searches. Highly scalable and stable, it suits multi-cloud environments, reducing alert volumes and speeding up investigations.
What are the key features?Splunk Enterprise Security is implemented across industries like finance, healthcare, and retail. Financial institutions use it for fraud detection and compliance, while healthcare organizations leverage its capabilities to safeguard patient data. Retailers deploy it to protect customer information and ensure secure transactions.
We monitor all Security Information and Event Management (SIEM) reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
