What options are available to perform whole disk encryption with Snow Leopard

We would like to encrypt the entire disk of a Snow Leopard workstation running some sensitive file, database and web services. PGP does not yet work for 10.6, and we cannot use FileVault as it is not compliant with FIPS and would require non-standard installation of services.

What whole-disk options are available that are known to work with Snow Leopard?


Solution 1:

It looks like the PGP WDE beta has opened. I'm beta testing it now and it appears to be working fine on Snow Leopard 10.6.2
