Summary

The Cybersecurity and Infrastructure Security Agency (CISA) and the Australian Cyber Security Centre (ACSC) released guidance on May 1, 2026, regarding the procurement, implementation, and maintenance of Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platforms. Organizations are advised to conduct thorough testing and manage costs, as implementation can be complex and expensive. The guidance emphasizes the importance of accurate alerting and the need for skilled personnel during the implementation process. Organizations must ensure that SIEMs are properly configured before integrating SOAR platforms to avoid operational gaps. The increasing complexity of IT infrastructure and the growing amount of sensitive data make these tools essential for effective threat detection and response. Hidden costs related to data ingestion and ongoing training should also be considered. The guidance includes specific recommendations for establishing a baseline of normal network activity to enhance detection capabilities. Key Points: • CISA and ACSC released guidance on SIEM and SOAR implementation on May 1, 2026. • Organizations face significant costs and complexity in deploying SIEM and SOAR platforms. • Accurate alerting and skilled personnel are crucial for effective implementation.
