USB pen drive security is one of those things that most people don't think about until it's too late
. It's very easy to lose or mislay a USB pen drive and even if it eventually turns up again, there can be hours or days of worry if your data isn't adequately protected. So it makes sense to use some kind of security software on your pen drive so that in the hopefully unlikely event of it doing a disappearing trick, you know that your data is safe from prying eyes.
Probably the easiest way of making sure that the files on your USB pen drive are secure is to use one of the commercially available programs. It's possible that your pen drive came with some kind of protection software although with the ever present drive to cut costs this is less likely nowadays as it's an extra expense that's not necessary for most purchasers. In fact, it's probably the exception rather than the rule for your pen drive to have anything other than the packaging around it.
Commercial software is your best bet when it comes to protecting the data on your USB pen drive. It's a few dollars more than searching forever to find a free piece of software and it will have the support and backup that you need for something as critical as this.
Take the plunge and you'll get a friendly, easy to use piece of USB pen drive security software that just gets on with the job of protecting your data without any fuss. Which means that you're much more likely to use the software and that your data will be kept safe whatever happens.
