Do get Lifelock. It is not expensive. It is not a guarantee, either, as there is only so much monitoring that they can do, but they act like an insurer; if, say, your bank account were raided and you could not prove it to the bank, Lifelock would reimburse you.
It always amazes me there is always insurance which will cover losses due to identity theft. It is a good thing insurance is there when security is not unless the plan is to break all the insurance companies in one fatal blow. Once upon a time, exists no longer and the sooner our nation wakes up from once upon a time, the quicker our nation may or may not right this ship. Sometimes in our present nuclear age, the nucleus has to be modified to fit the times. An insurance policy does sometimes help, yet those acts of God clauses worry me.
