I like the Thawte free option...

I thought the Thawte certificate is free only for personal use and not
for use in a business environment, but checking their web site doesn't
seem to indicate there are any restrictions of that type. It's
certainly an option.

There is also a free GnuPG encryption application that is the Gnu
version of PGP (which was purchased by a company) and there's an Outlook
plug-in for GPG.

For $19,95 a year you can get a Verisign class 1 certificate. They use the
credit card details to 'authenticate' the person. This is a little
better/secure than the Thawte version (only the e-mail address gets verified).
As far as I know there is no restriction on business use etc.

Drawback on PGP, GPG etc. is that every user needs to have some piece of
software installed. The advantage of x509 certificates is that almost every
e-mail client supports it.

The link is kinda hidden, because they rather sell you their services
