Google Buys Postini, Here Comes Security!

So Google has went out and bought Postini for over $600 million.

Postini provides corporate clients with communication security that in the future could integrate with both Goolge Talk and Gmail.  When I saw the first news article about this I thought that Postini would provide securtity solutions to companies that display valuable information on there servers that is then indexed by google and returned in the results set.

A Glasgow based company have also been working on similair security features for corporate clients http://websafesolutions.wordpress.com the service that Web Safe Solutions plan to provide once beta testing is finished will help to indentify files and folders indexed by search engines that my contain business sensitive information.

Is this the start of the security age?
