Gartner recently published a report by Jim Murphy, Gene Phifer, Ray Valdes and Eric Knipp: the 2010 Magic Quadrant for Horizontal Portals. In the report, Microsoft not only maintains its Leadership ranking but moves into the #1 position on the report – highest on both the Ability to Execute and Completeness of Vision axes – overtaking IBM.
Five vendors dominated portal selections during the latter part of 2009 and into 2010: Microsoft, IBM, Oracle, SAP and Liferay. Microsoft SharePoint is a consideration in more Gartner portal inquiries — over 70% — than any other vendor.
