Microsoft Expands Sentinel SIEM Platform for Better Security Response
Microsoft has expanded its Sentinel Security Information and Event Management (SIEM) platform, introducing new tools and partnerships to enhance security capabilities. The company is working with CyberArk to develop Security Copilot agents for the Microsoft Security Store, aiming to overcome industry fragmentation and enable more precise security responses.
The Sentinel data lake now unifies security data from Microsoft and third-party sources, making it easier to manage and analyze. Microsoft Sentinel serves as both a SIEM and a comprehensive security platform, offering open integration, multi-cloud coverage, and natural language workflows.
The newly launched Microsoft Security Store hosts Security Copilot agents, created by Microsoft and its partners. These agents, including those developed with CyberArk, can be refined and deployed to a Security Copilot workspace, streamlining incident investigation and reducing repetitive tasks. The Sentinel graph provides context to security tools, helping teams trace attack paths, understand impact, and prioritize responses.
Microsoft is extending its Sentinel platform with tools for unifying analytics and orchestrating security agents. The updates include a no-code agent builder and a coding platform enabled for Sentinel MCP Server, simplifying agent creation and deployment.
By expanding its Sentinel platform and partnering with companies like CyberArk, Microsoft is working to overcome the challenges of fragmented tools and signals in the cybersecurity industry. With AI as the operating system of modern defense, Microsoft aims to enable more precise and scalable security responses, helping teams detect early signals, understand impact, and defend at machine speed.
