Azure Sentinel is a cloud solution that combines two technologies: SIEM (security incident and event management) and SOAR (security orchestration automated response).
Azure Sentinel can be connected to different data sources across an organisation’s hybrid environment from devices, to users, to apps, to servers on any cloud. It is a single cloud solution for intelligent security analytics, event management, threat detection, threat visibility, proactive hunting, and threat response.
Traditional SIEMs lack modern capabilities to integrate with a multitude of data sources at one time to investigate, analyse and respond to threats. They are expensive to own and operate, often requiring upfront commitment and high costs for infrastructure maintenance and data ingestion. However, as it is built on the Azure cloud, Azure Sentinel has cloud scale and speed, and you pay for what you use just like other Azure cloud services.
Threat detection and response is an important stage of the cybersecurity lifecycle.
Azure Sentinel can help strengthen an organisation’s cyber security posture in four ways:
COLLECT – Through data connectors and integrations, Azure Sentinel combines data from all Microsoft and non-Microsoft sources, including users, devices, end point applications, infrastructure environment, and third-party data to understand the full digital estate.
DETECT – Built-in artificial intelligence and machine learning uses Microsoft’s analytics and threat intelligence to detect previously uncovered threats. It analyses signals from different data sources, reducing noise from alerts, minimising false positives, drilling, and analysing anomalous events to present incidents that really require attention.
INVESTIGATE – Azure Sentinel’s artificial intelligence hunts and investigates suspicious activities that could signal a breach. Its hunting capabilities help proactively detect potential issues before they cause damage. It allows organisations to understand how an incident or event occurred and how to stop it from happening again.
RESPOND – The artificial intelligence makes Azure Sentinel respond to the threat incidents and events rapidly. An organisation can create their own playbooks built on the foundation of Azure logic apps to respond to alerts. If an incident is discovered, built-in orchestration and automation goes to work to protect your environment.
Azure Sentinel allows organisations to see the threats clearer and eliminate the distractions.
Its versatile features can play a huge role in reducing the effort, alert volume and reactive processes that currently dominates the cybersecurity space.
