42% of Best-in-Class companies reduced help-desk time and the cost to remediate email related infections by more than 20%
65% of Best-in-Class companies reduced the volume of spam reaching user inboxes by more than 20%

These stats are courtesy of a June 2009 Aberdeen Group report on safe email. The focus of the report was to highlight the strategies best-in-class companies put in place in order to create an effective email security strategy, but I think there’s a lot more here if we just look a little deeper.
In the report, Analyst Carol Baroudi writes: “Well-financed email threat creators persist in propagating ever more sophisticated and potentially lethal attacks through the estimated 62 trillion spam messages sent last year……Add the rising value of sensitive data in a desperate market, and we have a set of trends that all point to critical reasons organizations cannot ignore their email vulnerabilities.”
Enterprise wikis are a valuable tool for businesses collaboration and knowledge management needs. A deployed wiki should have enterprise-grade security features that protect all of its information. When choosing a wiki to deploy, this is a tremendous benefit of deployed or SaaS products versus open source. Certainly, enterprise wikis can offer a safer environment for internal collaboration and sharing.
