See and stop threats across your business with Microsoft Sentinel.

Microsoft Sentinel is a cloud native security information and event management service, with security orchestration and automated response. It brings logs and alerts from many sources into one place, looks for patterns that indicate an attack, and helps analysts investigate and respond.

It suits businesses that need centralized security monitoring across Microsoft 365, Azure, firewalls, servers and other systems, often because of insurance, regulatory or client requirements.

A SIEM is only as good as the people and rules behind it. Poorly tuned, it produces noise and big bills. Well designed, it turns scattered logs into a few meaningful incidents.

Sentinel sits on a Log Analytics workspace, where data is stored and queried using Kusto Query Language. Connectors bring in data from Microsoft services with a few clicks and from other systems through agents, syslog and APIs.

Microsoft is bringing Sentinel and Defender XDR together in a unified security portal, so incidents from endpoints, email, identity and cloud sit side by side.

Sentinel gives the business central visibility of security events that would otherwise be scattered across tools. That shortens the time between an attack starting and someone noticing.

Automation reduces the load on small teams. Repetitive steps such as enrichment and containment can run on their own, leaving people to focus on real decisions.

For regulated or insured businesses, centralized logging and monitoring is a practical way to meet expectations for detection and evidence.

A firm sends Microsoft 365, Entra ID and firewall logs to Sentinel. An analytics rule detects a user signing in from two countries within minutes, followed by new mailbox forwarding rules. An incident is raised, a playbook disables the account and Infinity investigates within the hour.

This is an illustrative example of how the service is used, not a description of a specific client.
