And so it begins...
Symantec bought out MessageLabs and is (in their own words) "combining MessageLabs’ deep expertise in the SaaS market with Symantec’s rich portfolio of technologies".
The interesting thing is that Symantec does not really lead in the anti-virus market (in terms of quality, not market share. All antivirus products are about the same) or antispam (MessageLabs is excellent here).
So, what could they possibly bring to the party that MessageLabs doesn't already have?
MessageLabs has DLP but it is very simple and not really worth very much. The framework is certainly there though. Add some good DLP and voila - you have a product that is worth something.
