Although personal storage has had a negative impact on security with caused by mislaid memory sticks, Watkins argues that if users were to learn to use their storage media correctly, these could be a thing of the past. "We put encryption in the drive and you put your password in it -- now it's solid," he says.

"To eliminate your data is a multi-day process -- the only ones that do that are the government. If you don't do that, people can take your data off it. Trust me, we've taken data off disks with bullet holes in them, we've taken acid-spilled disks.

"We get a lot of drives from the CIA and the FBI and we take the data off them but if you encrypt it, it's safe. They can't break that encryption. Some governments don't like it. The Chinese won't buy them; the Russians won't let us in there. But if you encrypt it, it's safe. The only way to get into it is with some sort of backdoor that we could put on it."

As for alternative suppliers, Watkins simply asks, "Do you want all the British security data on a drive that's designed by the Chinese?" Closer to home, Watkins is more relaxed about the competition, and seemingly unworried by rivals' habits of dropping prices to increase market share.

"We all have our fingers in that dead body and we all point fingers about causing price wars," he says.
