Security Information and Event Management
SIEM = Security Information and Event Management

The leader of the field in longevity is ArcSight by Microfocus (after merger from HP) which is rather poorly rated by Gartner. They were the ones who identified the problem for the customer as "too much data" back in 2001. Microfocus targets legacy infrastructure.
The interesting component of the Gartner visionary category is Artificial Intelligence. The extent to which each of those visionary companies embrace AI seems to be the trigger for Gartner's classification. The "Old Man" of SIEM, ArcSight is now owned by a Vulture Capitalist and seems to be focused on quarterly results and not customer needs, even though they had the original insight that their customer's primary concern is that they were unable to handle the flood of data that the event monitoring tools, like Windows Events, were generating.
