Azure Sentinel

Standing watch, by your side. Intelligent security analytics for your entire enterprise.

Build next-generation security operations with cloud and AI

See and stop threats before they cause harm, with SIEM reinvented for a modern world. Azure Sentinel is your bird’s-eye view across the enterprise. Put the cloud and large-scale intelligence from decades of Microsoft security experience to work. Make your threat detection and response smarter and faster with artificial intelligence (AI). Eliminate security infrastructure setup and maintenance, and elastically scale to meet your security needs – while reducing IT costs.

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 again let a storage limit or a query limit prevent you from protecting your enterprise. Start using Azure Sentinel immediately, automatically scale to meet your organisational needs and only pay for the resources that you need.

AI on your side

Focus on finding real threats quickly. Reduce noise from legitimate events with built-in machine learning and knowledge based on analysing trillions of signals daily. Accelerate proactive threat hunting with pre-built queries based on years of security experience. View a prioritised list of alerts, get correlated analysis of thousands of security events within seconds and visualise the entire scope of every attack. Simplify security operations and speed up threat response with integrated automation and orchestration of common tasks and workflows.
