Browsing the site XAtrix for my dose of security related news and I encountered this article.Adhaero launches transparent document security for microsoft office providing permanent privacy for emails, documents and attachments.
I don't often use MS Products, but I can see the advantages of the offering made. If the company can hold true to their promise, this may prove invaluable. Just a friendly heads up to all the Windows users out there, there are people devoted to helping Windows security along to be better all the time. It may cost a little bit, but why not if it helps you secure your network.
