There may be functionality that you don't need in Enterprise that you'd have to pay for anyway (and I had a great time trying to get Microsoft to admit there's no real way to upgrade from Professional to Ultimate - which is basically the same as Enterprise). </div><div><br></div><div>My picking at this about a year ago led me to my opinion that it's complicated to deploy. Great if you have the scale and the infrastructure, which I didn't. But - if you do, you can integrate it, meaning that it's managed and deployed automatically, and can be fully controlled by your management system.</div><div><br></div><div>TrueCrypt is very good for end-users who have been trained to use it. I don't, however, have any experience using Whole Disk Encryption (I think they call it System Encryption/pre boot authentication). BitLocker requires hardware support (the Trusted Platform Module). PGP supports the Mac and Linux for their Whole Disk product.</div><div><br><div><div>On 21Aug10, at 19:35 , Edward Ned Harvey wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="color: rgb(31, 73, 125); ">Any wisdom comparing BitLocker versus TrueCrypt?<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="color: rgb(31, 73, 125); "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="color: rgb(31, 73, 125); "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="color: rgb(31, 73, 125); "><o:p> </o:p></span></div><div style="border-top-style: none; border-right-style: none; border-bottom-style: none; border-width: initial; border-color: initial; border-left-style: solid; border-left-color: blue; border-left-width: 1.5pt; padding-top: 0in; padding-right: 0in; padding-bottom: 0in; padding-left: 4pt; "><div><div style="border-right-style: none; border-bottom-style: none; border-left-style: none; border-width: initial; border-color: initial; border-top-style: solid; border-top-color: rgb(181, 196, 223); border-top-width: 1pt; padding-top: 3pt; padding-right: 0in; padding-bottom: 0in; padding-left: 0in; "><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><b><span style="font-size: 10pt; font-family: Tahoma, sans-serif; ">From:</span></b><span style="font-size: 10pt; font-family: Tahoma, sans-serif; "><span class="Apple-converted-space"> </span><a href="mailto:bblisa-bounces@bblisa.org" style="color: blue; text-decoration: underline; ">bblisa-bounces@bblisa.org</a><span class="Apple-converted-space"> </span>[mailto:bblisa-bounces@bblisa.org]<span class="Apple-converted-space"> </span><b>On Behalf Of<span class="Apple-converted-space"> </span></b>Edward Ned Harvey<br><b>Sent:</b><span class="Apple-converted-space"> </span>Saturday, August 21, 2010 1:08 PM<br><b>To:</b><span class="Apple-converted-space"> </span>'Back Bay LISA'<br><b>Subject:</b><span class="Apple-converted-space"> </span>[BBLISA] whole disk encryption<o:p></o:p></span></div></div></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">Presently, I have Mac and Windows laptop users.
