Chronicle and Sentinel are effective [[SIEM - Security Information and Event Management]] solutions that integrate SIEM capabilities with cloud-based data lakes. Chronicle, developed by Google X, uses BigQuery for its managed data lake, while Microsoft's Sentinel uses Azure Monitor Log Analytics. Both solutions support advanced detection and use cases but lack flexibility in deployment, being tied to their respective cloud platforms. A key advantage of cloud-based SIEMs is that data resides in the cloud provider’s storage, allowing it to be used not only for security operations but also for broader data analytics and engineering purposes. Additionally, Chronicle offers customer-friendly pricing with options based on employee count or data ingestion, including one year of telemetry retention at no extra cost.
