I am thinking about getting Zonealarm’s DataLock data encryption software. Basically I think that for laptops, it is a good way to make sure that if it gets stolen or I lose it (the reality is more like forget it) that nobody can access my data. It seems to run in the back ground so that you don’t know it is actually running. They say that it uses a pre-boot authentication in which users must provide the correct username and password before the operating system boot process will even begin. They also have a 24/7 password recovery service incase you forget your password. A couple of questions: 1) Is this pre-boot authentication something that will help keep the data secure? 2) What kind of encryption is used? 3) How hard will DataLock make getting the data from my hard drive?
