As far as encryption goes, you have a lot of possibilities…simply search “encryption software” and choose one you like.
Also, this is a great laptop tool especially for those who travel a lot:

“Protect data in the travel laptop …” you’d think that would be explicit enough.
What’s the operating system?
Encrypt all data? Encrypt the whole hard drive? Or encrypt only a folder? One drawback to folder encryption is the possibility that unencrypted, deleted files can be recovered.
Will you need to be able to centrally administer the encrypted system / files (retain an administrator access)?
I lean toward truecrypt, but I don’t know what you need.
In any case, use a strong password. Too often people will defeat a good encryption design by using an easily guessed password.
