In order for any product to be favorite requires that user also report
what OTHER similar products they trialed or used. A user that has only
used one FDE product doesn't have a favorite. I have one sister, so the
joke goes "you're my favorite sister". You do not let the user report
what other FDE products they have used or how many total FDE products
they have used (which must be greater than one). The survey is
worthless without this info.

I'll be keeping an eye on this survey, as I'm currently researching an FDE
solutions for about 20 of our users laptops. So far I've downloaded and
tested PGP WDE, next is CompuSec, I have a trial of SafeGuard Easy on order
(hopefully arrive in the post next week), and I'm arranging a conference
call with someone from PointSec to setup a trial of that product.

If anyone has any experience with any of the or other products, I'd be
interested in your views. Our requirements are:
Full Disk Encryption
Pre Boot Authentication
Activate Directory Integration
Easy Deployment (MSI/group policy)
Automated Encryption (no user intervention)

Cheers

Ben

Trivial: CompuSec is insecure by design. Just create a password reset floppy
on a second machine, start the recovery at the first, insert it, and there
you go. A trivial proof that they must have stored the key on the encrypted
disk as well.

SafeGuard Easy... well, has this shit become working now? On two test
machines I saw the boot loader completely crashing, totally ignoring any
keyboard response, or not accepting any of the correct passwords.

Hm... what about actual security? In terms of encryption this means to only
Open Source software, due to a matter of trust and verification of the
implementation. CompuSec has already been mentioned. SafeGuard Easy has been
proven to be horrible insecure, f.e. not properly locking memory regions
and then letting the keys being swapped out.

Yeah I tested it at home last night and didn't like it at all. There are a
number of other failings as well. Such as only allowing 1 user login, if a
consultant sends a machine in for repair, it would be useful to be able to
login without them having to expose their password. Another is only allowing
alphanumerical charactors in the login name, our users logon to the domain
as joe.bloggs, but they couldn't use this to login to CompuSec as it
contains a period, so its another username for them to remember. There is no
windows/directory service synchronisation, so it means another password for
users to remember, increasing the likihood of users writing down passwords
somewhere.

Thanks for the warning, I was going to install it on my laptop to test, but
I think I'll use a spare now, until I know it works! I've heard from other
people that it is stable, and offers all of the requirements listed below.

I assumed that most of the products mentioned used at least AES 128, and so
were fairly equal in that respect. Certainly all the datasheets for PGP WDE,
SafeGuard Easy, PointSec & CompuSec state that they are capable of AES 256,
and PointSec & SafeGuard say they are FIPS 140-2 compliant.

My major reason for looking into this is in the event that one of our
consultants has a laptop stolen, and someone might be able to retrieve
clients confidential information from the hard disk. We're not a goverment
organisation, bank or anything, but it would damage the company's reputation
if a client were to find their information had been lost/made public!

It was one example from the non-FDE products from Ultimaco provides. Over
the years we've seen many such implementation errors, and one really can't
reasonably trust the vendor for now having created a proper implementation.

The issue about checking the correctness of the implementation. That means
not just the cipher, but also the key management (including key creation and
key destruction) and the rest (f.e. that it doesn't store a backup of the
key somewhere else). Didn't we learn something from PGP 5.x?

I'd bring to the table Pointsec - we use this and it's good and scales
to the enterprise for key recovery etc, and also potentially MS
Bitlocker in Vista. Not used the latter, obviously treat with
caution, but it does seem to be ticking the boxes so far from brief
conversations with our architects...

Fair enough.

I hate to blow my own trumpet but have you thought about SafeBoot
(www.safeboot.com)?

In my biased opinion it works better than the other products you're
looking at - for only 20 machines you'll not need some of the more
advanced stuff like AD integration, webhelpdesk etc, but you might
find those features technically interesting.

Just do not create a password reset floppy and you'll be fine. Make an mbr
backup with an external software. Free compusec allows one to create a
temporary service password. On login you have got 2 seconds to press F1
where you can set service password. Login is "Service". The password expires
automatically when user logs in with their login.

You can create a password reset floppy from any installation, and the worst
about Free CompuSec is that it will work on any other machine.
