As a licensed financial advisor, I told my clients to do SOMETHING. Whether you choose Lifelock or one of its competitors, or try to do it on your own, doesn't matter. The advantage to the services is that they don't forget to ask for the reports, file the paperwork, and that sort of thing. They also provide, in Lifelock's case, $1,000,000 insurance. That may be worth the fee to you. I've also found that people start with the best of intentions to maintain their credit files, and do the due diligence. After about three months, the "fun" wears off, and after twelve months, I bet only a very small percentage are still doing it. For my money and piece of mind, it is worth using one of the services.
