To export high-severity alerts for a third-party SIEM solution, which service in Azure is recommended?

Using Azure Event Hubs to export high-severity alerts for a third-party SIEM solution is a recommended approach due to its ability to handle large volumes of data with low latency. Azure Event Hubs is designed specifically for data streaming and ingestion, making it ideal for collecting event data like security alerts. It can handle millions of events per second, which is crucial for organizations that need to monitor and respond to security threats in real-time.

Moreover, Event Hubs is compatible with various analytics services and third-party solutions, enabling seamless integration with SIEM tools. This allows organizations to send security alerts directly to their SIEM systems without extensive transformation or processing delays, facilitating immediate analysis and response to threats.

In contrast, other options like Azure Cosmos DB, Azure Event Grid, and Azure Data Lake serve different purposes. Azure Cosmos DB is a globally distributed database service that is more suited for storing data rather than streaming it, which is not ideal in the context of high-severity alert exportation. Azure Event Grid is excellent for routing events between services in a serverless architecture but does not function as an ingestion or streaming tool for high-volume alerts. Similarly, Azure Data Lake is primarily used for storing large amounts of data for analytics but is not specifically tailored for real
