Utilization of PGP for improving on email security

Do you think the utilization of PGP for improving on email security for sensitive material being transfered to and from a company within the banking sector is satisfactory or would another product be preferable?

I assume that the need for security in e-mail exchanged with financial institutions is to provide confidentiality for the message, assure message integrity, and offer non-repudiation of the message from the sender. You may want to evaluate PGP or any other product against these three requirements.

Digital signatures often provide these kinds of functions, and you should keep an eye on the development of the XML Signature, a joint specification of the Internet Engineering Task Force and World Wide Web Consortium (https://www.w3.org/Signature/). You also may want to review the ebXML technical report on security risk assessment issued in May 2001 (http://www.ebxml.org/specs/secRISK.pdf).
