I have personally bought one to simply crack open to see how hard it would be to get at the Cryptochip and let me say, it was a mess. The internal components are sealed with an epoxy to help keep the drive from being tampered with. I personally have had one around my neck while scuba diving and never had a problem with it after it was dry.

Thought they are not 100% dust/water proof, nothing ever is, it has a tolerance that means it will be able to handle more then a human can without specialized equipment. They are sealed and protected from physical destruction by those means to a very high level of tolerance. MIL-STD-810F & MIL-STD-810G (Waterproof & Dustproof) means that these things are "military grade" when it comes to dust and water. It isn't easy to get this certification and regardless of your opinion of the US Government, it is fair to say that it is a very high standard when security is concerned. NIST FIPS 140-2 Level 3 is a big deal in some cases. The encryption used are standards that have been widely accepted to be "secure" but that isn't 100% why I like them. For me, the cost is justified by the physical protection that you don't get with most other drives.

I personally own several IronKey flash drives.
