Azure Sentinel Security and Monitoring Solutions

Azure Sentinel is a cloud-native security information and event management (SIEM) solution that provides real-time threat detection and incident response capabilities. It's designed to help organizations detect, investigate, and respond to cyber threats.

With Azure Sentinel, you can collect data from various sources, including Azure resources, on-premises systems, and third-party services. This data is then used to identify potential security threats and alert you to take action.

Azure Sentinel's advanced analytics and machine learning capabilities enable it to detect even the most sophisticated threats. It can also integrate with other Azure services, such as Azure Active Directory, to provide a more comprehensive security posture.

One of the key benefits of Azure Sentinel is its scalability and flexibility. It can handle large volumes of data and scale up or down as needed, making it an ideal solution for organizations of all sizes.

Azure Sentinel is a cloud-native security information and event management (SIEM) and security orchestration, automation and response (SOAR) solution that operates on the Azure platform. It can collect data and detect, investigate and respond to threats.

Azure Sentinel helps businesses secure their IT operations and streamline workflows for better efficiency regardless of scale. It's a powerful tool that provides a birds-eye view across all the enterprises you have set up on Azure.

The four primary capabilities of Microsoft Sentinel are security data collection, threat detection, investigation and automated response, which you can perform from one central panel. This means you can collect data from users, devices, applications, and more, detect potential threats, investigate suspicious activities, and respond to incidents automatically.

Azure Sentinel secures your business against threats by working according to four security operations areas: Collect, Detect, Investigate, and Respond. Here's a breakdown of what each area does:

Azure Sentinel collects data in real-time through connectors to data sources such as Office 365, Microsoft 365 Defender, or Azure Kubernetes Service. It also supports open standard formats like CEF and Syslog, making it easy to collect data from more places.

Azure Sentinel is a powerful tool that offers a wide range of features and benefits to help you strengthen your organization's security posture. It provides a cloud-native security information and event management (SIEM) and security orchestration, automation, and response (SOAR) solution that helps you collect data from various sources, analyze it for threats, and respond to incidents quickly and effectively.

Azure Sentinel offers a data grant of up to 5 MB per user/day to ingest Microsoft 365 data, including Azure Active Directory (Azure AD) sign-in and audit logs, Microsoft Defender for Cloud Apps shadow IT discovery logs, Microsoft Information Protection logs, and Microsoft 365 advanced hunting data.

Azure Sentinel's features and benefits make it an ideal solution for companies that are in or transitioning to the cloud. Its scalability and customization capabilities allow it to adapt to the security needs of each moment, with the necessary infrastructure expansion and maintenance facilities.

Azure Sentinel offers a flexible pricing model that suits various needs and budgets. You can choose from two main billing types: Pay-as-you-go and Commitment tiers.

With Pay-as-you-go, you're billed per gigabyte (GB) for the volume of data ingested for security analysis in Microsoft Sentinel and stored in the Azure Monitor Log Analytics workspace. This model helps you reduce infrastructure costs by automatically scaling resources according to your business's needs and paying for only what you use.

You can also opt for the Commitment tiers, which enables you to commit a specific amount of GB that Logs Analytics can store daily. This model can save you up to 65% compared to pay-as-you-go, making it a cost-effective option for large-scale data storage.

Azure Sentinel also offers a free plan for the first 31 days, allowing you to try the service without any additional cost. During this trial period, you can ingest up to 10 GB/day of log data for free, subject to a 20 workspace limit per Azure tenant.

Here are the purchase tiers and discounts for pre-purchase plan Commit Units:

Microsoft Sentinel offers a pay-as-you-go pricing model, where you're billed per gigabyte (GB) for the volume of data ingested for security analysis and stored in the Azure Monitor Log Analytics workspace.

You can choose between two types of logs: Analytics Logs and Basic Logs, with Analytics Logs supporting all data types and providing comprehensive analytics, alerts, and limitless queries.

The pay-as-you-go pricing model is measured in GB, with no flat rate listed, but you can save up to 65% by committing to a specific amount of GB that Logs Analytics can store daily.

Microsoft Sentinel also offers a free plan for the first 31 days, with new workspaces able to ingest up to 10 GB/day of log data at no cost, subject to a 20 workspace limit per Azure tenant.

In addition to the free plan, Microsoft Sentinel offers a free data source for Azure Activity Logs, Office 365 Audit Logs, and Alerts from Microsoft Defender for Cloud and other services.

Here's a breakdown of the Microsoft Sentinel Commit Units pre-purchase plan:

Microsoft Sentinel also offers a 1-year pre-purchase plan, which can save you up to 25% on your Microsoft Sentinel Commit Units, and you can use these units at any time within 12 months of purchase.

Microsoft Sentinel offers a special benefit for customers with Defender for Server Plan 2 enabled.

You'll get 500 MB per VM per day of free data ingestion, specifically for security data types collected by Defender for Cloud.

The allowed data types include SecurityAlert, SecurityBaseline, SecurityBaselineSummary, SecurityDetection, SecurityEvent, WindowsFirewall, SysmonEvent, ProtectionStatus, and Update and UpdateSummary.
