The platform uses many connectors to get data from Microsoft services and other security tools. Sentinel can read different types of data, even custom ones using APIs and Common Event Format. This helps security teams watch for threats everywhere in the company.
Sentinel puts SIEM and XDR in one platform. Users can see coverage, get advice, and check threat details in one place. It works with the MITRE ATT&CK framework to show rules and detection numbers for each tactic. This clear view helps organizations understand threats and gaps better than old SIEM tools.
Note: Sentinel’s data lake lets teams store lots of data for less money. Security teams can look at big sets of data, do deep checks, and keep wide visibility without spending a lot.
Multiple Sources
Microsoft Sentinel links to many data sources. It works well with Microsoft tools and other products. The platform has connectors for Azure Active Directory, Microsoft Defender, and Defender for Cloud. On-premises sources like Windows Events and firewalls also send data to Sentinel. The system uses agents, APIs, and service links to get data from servers, devices, and cloud platforms.
Many groups add third-party security tools like Palo Alto Networks and Fortinet firewalls, endpoint detection, anti-malware, network detection, and mail security. For example:
EasyDMARC sends email alerts to Sentinel, helping find phishing and spoofing.
Jamf Protect shares Mac security data, so teams can watch Mac, Windows, and Linux devices.
Service providers gather DMARC data from different tenants, making threat detection better.
Sentinel’s design lets teams build custom connectors for special needs. Playbooks help connect things fast and respond quickly to threats. The platform can handle over 20 billion events each day, making it great for big companies that want strong cybersecurity.
Threat Detection and Analytics
AI and Machine Learning
Microsoft Sentinel uses AI and machine learning to find threats. It looks at billions of logs from the cloud, networks, and devices right away. Machine learning helps sort and label alerts. This makes it easier for security teams to handle alerts. The system does simple security jobs by itself. This lets experts spend more time on hard problems. Sentinel works in the cloud, so it can watch and study things all the time. It grows easily and gives better analytics than old SIEM tools.
Sentinel’s AI can look at huge sets of data fast. Security teams spot patterns and strange things that show threats quicker than doing it by hand. Sentinel puts the most risky problems first. Teams can fix the most important threats first. Automation and playbooks help handle incidents faster. They cut down on useless alerts and help teams work together. These tools mean less work for people and make things run smoother.
Behavioral Analytics
Sentinel uses behavioral analytics to make threat protection stronger. It learns what normal actions look like for users and apps. This helps it spot strange actions and find hacked accounts. AI and machine learning find risky actions and possible threats. Sentinel checks how sensitive and important hacked things are. This helps teams know which problems to fix first.
Sentinel’s user and entity behavior analytics (UEBA) work with the MITRE ATT&CK framework. This helps teams find and fix threats better. It uses ideas from Gartner’s UEBA model. Security teams watch and study actions all the time. This helps them spot strange behavior and hacked accounts. Sentinel’s UEBA makes threat finding and analytics better for big companies.
Sentinel lets each customer use up to 50 fast analytics rules. These rules run every minute and only wait two minutes. Sentinel checks when data comes in to make things faster. This helps find threats quickly and makes security teams respond faster.
Real-Time Threat Detection
Custom Alerts
Microsoft Sentinel helps teams find threats right away. Security teams can make their own alerts for their needs. These alerts have clear titles and descriptions. This helps analysts know what is happening fast. Custom rules show important event data in the alert panel. This makes work easier and helps teams investigate faster. Sentinel links related alerts together as incidents. This makes advanced threat protection better. Teams can change rules to fit their own threats. This lowers false alarms and helps find real problems.
Custom alerts in Sentinel cut down on extra alerts. Analysts can pay attention to real threats. This helps teams respond faster and keeps protection strong.
Reducing False Positives
Sentinel uses AI to sort logs and remove useless ones. This stops teams from seeing too many alerts. Security teams can focus on real threats. Machine learning and Fusion technology group weak alerts into strong incidents. This means teams see fewer false alarms. Watchlists and user behavior analytics hide alerts from safe users or devices. This lowers the chance of false positives even more.
A financial company saw false positives drop from 20% to under 10%. This is much better than most companies. Sentinel’s Fusion engine can cut alert fatigue by up to 90%. These changes help teams spend less time on fake alerts. They can spend more time on real threats. This makes advanced threat protection stronger.
Sentinel’s real-time threat detection helps teams find and stop threats in minutes. They do not have to wait hours or days. This makes Microsoft Sentinel a top choice for threat protection and detection.
Automated Response
Playbooks
Microsoft Sentinel uses playbooks to help with threats. Playbooks are powered by Azure Logic Apps. They start working when Sentinel finds a threat. This can be a bad user or a strange login. The playbook does several things:
Sentinel makes an incident for the threat.
The playbook opens a ticket in an IT system like ServiceNow.
It sends messages to security teams using Microsoft Teams or Slack.
Senior admins get emails with details and choices to block or ignore the user.
If they block, the playbook turns off the user in Microsoft Entra ID and blocks the IP address on the firewall. If ignored, it closes the incident and ticket.
This shows how automated threat response works. Sentinel playbooks work with Microsoft Defender for Endpoint, Azure Active Directory, and other tools. They help security teams respond fast and in the same way every time. These workflows cover finding, checking, stopping, telling, and passing on threats.
Playbooks save time and help teams stop threats before they spread.
Orchestration
Sentinel’s orchestration lets teams automate hard incident response jobs. Automation rules tag, assign, or close incidents based on how bad and what type the threat is. Playbooks can change actions to fit each threat.
Groups check how well Sentinel works by looking at things like how fast they find, respond to, and stop threats. Automation rules add notes like "Closed by automation rule," which helps with reports and reviews. This way, teams do not get too many incidents and can focus on big problems.
Sentinel’s automated response helps teams handle incidents fast, lowers costs, and keeps protection strong against new threats.
Threat Intelligence and Hunting
Intelligence Feeds
Microsoft Sentinel connects to many outside threat feeds. These feeds show real-time signs of danger, like bad IPs, domains, and file hashes. Sentinel works with providers such as ANY.RUN, Cybersixgill, ESET, and IBM X-Force using STIX/TAXII connectors. Security teams can put together threat data from different places. This helps make alerts better by adding more details.
ANY.RUN updates its feeds every two hours. This gives new threat information from live sandbox tests.
Each sign has links to sandbox sessions. This helps teams look deeper into threats.
Expert analysts check the data first. This means almost no false alarms and less work for analysts.
Sentinel playbooks use Azure Logic Apps. They match signs with logs, send alerts, and block bad IPs.
Teams can use APIs and SDKs to connect Sentinel with SIEM, XDR, and firewalls easily.
Microsoft Sentinel puts real-time threat intelligence right into its workflows. This helps teams find threats early and respond fast.
Sentinel can also bring in threat intelligence using STIX format. The TAXII connector gets data from TAXII servers. It handles many STIX object types like threat actors, attack patterns, and indicators. This easy integration helps teams find and study threats better.
Proactive Search
Sentinel lets analysts look for threats that normal alerts might miss. The platform gathers data from devices, users, apps, and systems. This gives teams a full view of what is happening. AI and machine learning help spot strange or new threats. This supports finding threats before they cause problems.
Security teams use Kusto Query Language and the MITRE ATT&CK framework to investigate threats. Sentinel’s MITRE ATT&CK blade shows tactics and techniques on a map. This helps teams see where they need more coverage. Analysts can tag rules and searches with ATT&CK techniques. This matches their work with industry standards.
Sentinel lets teams make custom rules and automatic responses for suspicious actions.
Proactive hunting tools help find zero-day threats before they get worse.
Automation with Azure Logic Apps helps stop threats faster and lowers manual work.
