The benefits of SIEM tools enable an organization to get a big-picture view of its security events throughout the enterprise. By bringing together security log data from enterprise security controls, host operating systems, applications and other software components, a SIEM tool can analyze large volumes of security log data to identify attacks, security threats and compromises. This correlation enables the SIEM tool to identify malicious activity that no other single host could because the SIEM tool is the only security control with true enterprise-wide visibility.
