Security information and event management (SIEM) systems have been around for a dozen years or so. During that timeframe, SIEMs evolved from perimeter security event correlation tools, to GRC platforms, to security analytics systems. Early vendors like eSecurity, GuardedNet, Intellitactics, and NetForensics, are distant memories; today’s SIEM market is now dominated by a few leaders: LogRhythm, McAfee (aka: Nitro Security), HP (aka: ArcSight), IBM (aka: QRadar), and Splunk.
Of course, there is a community of innovative upstarts that believe that SIEM is a legacy technology. They proclaim that log management and event correlation can’t keep up with the pace of cybersecurity today, thus you need new technologies like artificial intelligence, machine learning algorithms, and neural networks to consume, process, and analyze security data in real-time.
