Saw this come across one of my Google Alerts and wanted to pass it around.  Gartner’s Magic Quadrant is made up of four sections (quadrants):

• Leaders
• Score high on ability to execute and completeness of vision
• Challengers
• Score high on ability to execute and lower on completeness of vision
• Visionaries
• Score lower on the ability to execute and higher on the completeness of vision
• Niche Players
• Score lower on both criteria but are new to additions to the Magic Quadrant

For more information see this Wikipedia entry on the Magic Quadrant.

The three reports are:

• Secure Email Security with Symantec Brightmail Gateway
• Security Information and Event Management with Symantec Security Information Manager
• Content-Aware Data Loss Prevention with Symantec Data Loss Prevention
