In the face of budget constraints and personnel shortages, modern security teams must adopt agile practices to maintain effective operations, necessitating the use of agile Security Information and Event Management (SIEM) systems that emphasize speed, flexibility, and efficiency. Agile SIEM solutions, particularly those that are cloud-native and API-driven, are essential for streamlining workflows and enabling interoperability with other systems, allowing security teams to respond swiftly to incidents and enrich data for more precise detections. Furthermore, these solutions offer cost-efficiency benefits over traditional on-premises SIEM systems by automating cumbersome tasks and providing robust customer support services, ensuring that even lean security teams can manage their operations without compromising on effectiveness.
