Email Encryption

By Tink! ·
Windows 2003 Server (with Exchange Server), clients run Outlook 2003

Can I, and how do I enable encrypted emails for outgoing messages?

How does the receipient open these encrypted emails?

I am asking this because much to my horror I found out that our CEO sent out an email containing the company's bank info to an International client to precipitate a wire transfer. As this is the easiest way for him to communicate and transfer information with our international clients, I need to make it safe for him to do so.
Thanks in advance for your help!

Oh fun.

I was actually at Nortel and tested the beta versions of Entrust about 10 years ago. Since then Nortel split the company off.

Both your users, and the external recipients have to have compatible encryption software. You probably want digital signatures as well.

Entrust is one product I've used, even after I left Nortel. It is the Government of Canada standard.

Rather than me hashing out the description, got to their website. It isn't a one size fits all solution.

Hope that helps.

ZixCorp is another solution. We used that with much success.

Thanks for the suggestions thus far.

However, I was hoping for a non-3rd party solution. Specifically one within Exchange Server. Going to Microsoft Technet there appears to be an Encryption ability within Exchange Server.

Looking for someone who can clarify these abilities and detail how to implement this.

To encrypt mail each user needs to have their own certificate. You can give users certificates using a Certificate Authority. You can set up a Certificate server in your organisation then users can use encryption facilities in Outlook, the user only needs to send their public key to users to allow them to decrypt mail sent to them.

See http://en.wikipedia.org/wiki/S/MIME

I understand your desire not to go 3rd party but thier are two things you must realize. 1st the ecryption will only work if you have the cooperation of the reciever and the sender. The sender will have to remeber to encrypt the message and the reciever will have to already have the "decoding" established. PGP (Pretty good Privacy) comes to mind as a good example. The only ones who can open the "file" email or whatever are those who already have the software to do so and have receievd the key required. BUT that also means the sender remembers to encode the message. I am unsure of any way to make the system fool-proof. The last person's answer would be nice but I think your also concerned about the accidental sending of the information to the wrong parties? Perhaps also look into MS IRM (Information rights management)
