Azure Sentinel

Simplify security operations with intelligent security analytics and scale as you grow

Build next-generation security operations powered by the cloud and AI

Modernise your security operations centre (SOC) with Microsoft Sentinel. Uncover sophisticated threats and respond decisively with an intelligent, comprehensive security information and event management (SIEM) solution for proactive threat detection, investigation, and response. Eliminate security infrastructure setup and maintenance, and elastically scale to meet your security needs—while reducing costs as much as 48 percent compared to legacy SIEM solutions.1

Collect data at cloud scale—across all users, devices, applications, and infrastructure, both on-premises and in multiple clouds

Detect previously uncovered threats and minimise false positives using analytics and unparalleled threat intelligence from Microsoft

Investigate threats with AI and hunt suspicious activities at scale, tapping into decades of cybersecurity work at Microsoft

Respond to incidents rapidly with built-in orchestration and automation of common tasks

Limitless cloud speed and scale

Invest in security, not infrastructure setup and maintenance, with the first cloud-native SIEM from a major cloud provider. Never let a storage limit or a query limit prevent you from protecting your enterprise. Start using Microsoft Sentinel immediately, automatically scale to meet your organisational needs, and pay for only the resources you need. As a cloud-native SIEM, Microsoft Sentinel is 48 percent less expensive and 67 percent faster to deploy than legacy on-premises SIEMs.
