What Is Microsoft Sentinel and How It Protects Your Business

As the internet evolves, so do the constant threats to your data and privacy. Businesses in particular face a constant storm of sophisticated cyberattacks. From ransomware to advanced persistent threats, traditional antiviruses are no longer adequate protection, and they haven’t been for quite some time. You need intelligence, automation, and a proactive stance: that's where Microsoft Sentinel comes in.

What is Microsoft Sentinel?

Microsoft Sentinel is a Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) solution delivered as a cloud service. Mouthfuls, right? It might help to simply think of it as your organisation's central nervous system for security.

Sentinel's power begins with its unparalleled ability to ingest security data from virtually any source across your entire IT landscape. It goes far beyond just Microsoft services. Imagine having a central hub that pulls in:

Cloud Environments. You get comprehensive logs from your Microsoft 365 services (Exchange Online, SharePoint Online, Teams), Azure resources (VMs, databases, networks), and even other cloud providers like Amazon Web Services (AWS) and Google Cloud Platform (GCP).

On-Premises Infrastructure. You can review security event logs from your physical servers, domain controllers, Active Directory, network devices, and traditional firewalls.

Endpoints. Detailed activity from every laptop, desktop, and mobile device, providing visibility into user behavior and potential malware.

Applications. Security logs from critical business applications, both SaaS and custom-built.

Threat Intelligence Feeds. Integration with various threat intelligence sources to enrich your data with known malicious IPs, domains, and attack patterns.

This universal data collection is the critical element here. Instead of piecing together alerts from multiple unrelated systems, Sentinel provides a single, unified view of activity. This holistic perspective is essential for detecting sophisticated attacks that often span multiple layers and environments. This ensures no critical event goes unnoticed.

What Else Can Sentinel Do For You?

Using AI, machine learning, and Microsoft's vast threat intelligence, Sentinel doesn't just log events; it identifies subtle patterns and anomalous behaviors that indicate real threats, often before they escalate.

It also allows you to automate responses to common threats, neutralizing them rapidly without manual intervention.

Security analysts can actively "hunt" for new, unknown threats in your environment using query languages.

All in all, Sentinel gives you an intelligent view of your entire security posture, helping you detect, investigate, and respond to threats almost instantly.

Why Every Business Needs Sentinel (and Why an MSP is Critical)

While Sentinel is a powerful tool, deploying and managing it effectively requires specialized expertise. This is precisely why partnering with an MSP, like Dolphin IT Solutions, is your smartest move.
