To get an idea of how vital a SIEM platform is to enterprise security, consider the scale of security incidents and the data involved. A large enterprise may generate more than 25,000 events per second and require 50 TB or more of data storage. SIEM’s efficient data filtering prioritizes critical security issues, enhancing manageability. Choose the right tool to secure your digital operations and leverage free trials or demos for a test run before committing.
SIEM systems often rely on data from various security mechanisms, so knowing the common network security protections could help you interpret and prioritize these events more effectively.
