We've just produce another new eBook that's with our compliments, for anyone subscribed to our SDU Insiders list.
If you've wondered about implementing TDE and aren't sure, this guide should help. If you've already implemented it and aren't sure if you've done things right, again this should help.
The book also includes a frequently-asked questions section with questions we've commonly been asked by our clients.
You'll find it here: http://tdebook.sqldownunder.com
I hope you find it useful.
