The digital security landscape is constantly challenged by sophisticated threats, making the role of Security Information and Event Management (SIEM) systems more critical than ever. In the 2024 Gartner® Magic Quadrant™ for SIEM, Microsoft and Splunk have been recognised as leaders, demonstrating excellence in vision and execution in the SIEM space.

Gartner said in their 2024 report that “The SIEM market grew from $5.03 billion in 2022 to $5.7 billion in 2023 (see Market Share: All Software Markets, Worldwide, 2023), a 13% annual growth rate compared to a 22% increase the previous year. The primary drivers of a SIEM purchase are threat detection, response, exposure management and compliance. Buyers are seeking a SIEM ecosystem with broad and deep capabilities to satisfy multiple security and business use cases with capabilities to support a diverse environment.”

The Significance of SIEM in Cybersecurity

SIEM technology is essential for organisations to effectively manage security events and information. It provides real-time visibility across an organisation’s information security systems (multi vendor), providing single pane of glass event log management, compliance reporting, and incident response capabilities. The ability to swiftly detect, analyse, and respond to security incidents is what makes SIEM a cornerstone of enterprise security strategies.

Friends and Foes?

In 2023, Splunk and Microsoft agreed to partnering to help build Splunk’s enterprise security and observability offerings on Microsoft Azure. This means that Splunk solutions are now available for purchase on the Microsoft Azure Marketplace as well as AWS Market place. This is great for both parties and Microsoft Partners who sell and deploy Azure Services to their clients.

Microsoft’s Leadership with Sentinel

Microsoft has been acknowledged as a leader in the Gartner Magic Quadrant for SIEM for its comprehensive, cloud-native solution, Microsoft Sentinel¹. According to Gartner, Microsoft Sentinel stands out with its unified security operations platform, blending SIEM, XDR, AI, Threat Intelligence, and extended posture management into a single experience. This platform is powered by generative AI, offering end-to-end protection and consolidating various security operations tools into a coherent experience.

Strengths:

• AI and Automation: Enhances threat detection and response capabilities.
• Unified Experience: Offers a seamless blend of SIEM and XDR functionalities.
• Cost Efficiency: Delivers up to 234% ROI over three years and reduces costs by up to 44%¹.

Best Fit for Sentinel:

Gartner cite Microsoft Sentinel as being best for organisations that require or demand a cloud-native SIEM solution with advanced AI capabilities and integration with other Microsoft security products will find Microsoft Sentinel to be an ideal fit. Sentinel works with a huge number of external cloud and on-premises data connectors (including Splunk).

Splunk’s Data-Centric Excellence in SIEM

Splunk remains a joint leader in the SIEM market, praised as always for their data-centric security analytics solution, The Enterprise Security application from Splunk is available both on-premises and as SaaS. Splunk provides pricing flexibility, which can be based on daily data ingestion or cloud workloads, referred to as Splunk Virtual Compute. Splunk primarily serves large enterprise organizations in North USA

Splunk have said they are launching a new AI Assistant for Security, which will be integrated with Enterprise Security to enhance detection and response functions. Cisco finalized the acquisition of Splunk on March 18, 2024 and we expect to see integration and cross pollenisation of their combined portfolio at somepoint in 2025.

Gartner point out that currently Splunk has a significantly higher-than-average cost compared to other vendors in their report, is more complex to deploy and configure (measured in pro services days) and currently low numbers of sales support staff outside the US – though with Cisco’s aquisiton of Splunk this is likely to change over the next 18-24 months.

Strengths:

• Overall observability: The Splunk platform can integrate security, IT, application and other data sources. This, coupled with its federated search and analytics capabilities across third-party data stores, is a strength for clients seeking to build highly enriched queries and alerts.
• Extensive integration: Splunk’s integration of SOAR enhances a wide range of common SIEM use cases. Clients wanting quick time to production automation for common SIEM operational functions will find Splunk’s library of playbooks a strength.
• User interface: Splunk’s UI and dashboard provide significant customization. Clients requiring custom animations and visualization for specialized monitoring, such as OT or financial systems, will find the UI editor an overall strength

Best Fit

Splunk is particularly suited for very large organisations that value a data-driven approach to security and need powerful analytics to manage complex security environments. Microsoft is actually one of Spunk’s largest customers.

Conclusion

Microsoft and Splunk continue to lead the SIEM market with their innovative solutions. Sentinel offers a world-class leading, cloud-native, AI-enriched platform that simplifies operations and accelerates threat resolution.

Splunk provides a robust, data-centric approach to security analytics, enabling organizations to respond to threats with speed and precision and is ideally suited for the largest of enterprises as well as those who remain mainly on-prem and less “all in with cloud”. Splunk also has a strategic alignment and integration with Microsoft Sentinel.

As a Microsoft and Cisco leading UK partner, we are excited to be working with both Cisco and Splunk (Cisco) in this space with the abiluty to guide and consult around customer hosted, Azure hosted and cloud-native SIEM solutions. We also love ther fact that we can now meet customers on their ground with the ability to deploy Splunk on Azure via the market place to our clients.
