They have a cable lock system to secure it to the seat frame or other permanent part of the interior. If you had the backpack version then you could take it with you without raising any eyebrows. They also make bags specific for bikes that looked pretty cool. Ebay usually has cheaper prices than most of the online stores.

Maybe not as tough as a steel safe, but it would certainly be more of a hassle than the normal smash-and-grab vehicle burglar is going to want to deal with.
