Security Information and Event Management (SIEM) systems have been around for a dozen years or so. LogRhythm, McAfee (aka: Nitro Security), HP, IBM and Splunk dominate SIEM market. Security analysts often want to dig deep into security alerts by monitoring and investigating host behavior, so EDR (i.e. CarbonBlack, Countertack, CrowdStrike, Guidance Software) is an essential component of SOAPA. Incident response platforms (IRPs) are giving rise to IRPs such as Hexadite, Phantom, ServiceNow and Swimlane.”]
