Our Liferay review has been updated for release 6.2. The key changes are related to new mobile delivery capabilities (along with a new mobile SDK) and a re-designed admin interface. We also take a critical eye to Liferay's new Marketplace, its new collaboration architecture, as well as its personalization capabilities.
As you know, Microsoft SharePoint 2013 represents a major upgrade to SharePoint 2010. However, we argue that for enterprise portal services, it’s more an upgrade in degree than kind, even if the much vaunted (though little used) “app store” gave it some short-term street cred. What's new is Microsoft’s emphasis on the cloud-based version of SharePoint, now an integral part of Office 365. We evaluate portal services in the cloud, and much more.
You can of course download detailed evaluation of each of these vendors as well as the complete report here.
Besides this report, there are a number of advisory papers as well as webinars related to Portals that subscribers can access as well.
